1 Introduction The Kodak i1800 Series Scanners are high-volume production scanners which include image processing technology that can improve image quality and sometimes make the reproduction better than the original. You can use the ISIS Driver or TWAIN Datasource (both are available on the CD that is included with the scanner) or Kodak Capture Software to enable image processing.
Image outputs The i1800 Series Scanners are duplex scanners. This means both the front and the rear side of each document may be captured. For each side captured, the scanner creates a black and white and color/ grayscale image. The host application controls which of these images is transferred to the host to be stored as an image file. The Kodak i1800 Series Scanners can return black and white, grayscale or color images to the host. Below is a description of the valid combinations.
Another example of a simultaneous output where all four images are returned to the host would create the following four files: • Front grayscale: FG.jpg. This image file represents the contents of the front side of the document using 8-bits per pixel. • Front black and white: FB.tif. This image file represents the contents of the front side of the document using 1-bit per pixel. • Back grayscale: BG.jpg. This image file represents the contents of the rear side of the document using 8-bits per pixel.
2 Best Practices This chapter provides you with recommendations for program logic, which will allow you to interact efficiently with the i1800 Series Scanners. This high-level information is not intended to be used as a coding guide.
Scanner setup To set up the scanner: 1.
Enable scanning The host must issue a Scan command to enable scanning before documents can be transported through the scanner. If scanning has not been enabled, the feeder and transport system will not turn on. Initiate polling Initiate host system polling of the scanner to ensure scanned document images are transferred from the image buffer to the host system. Polling should continue until scanning is disabled.
To receive subsequent pending errors, the host must execute a Test Unit Ready command. If a deferred error is pending, the Test Unit Ready command will terminate with a Check Condition Status. The host follows with a Request Sense command. The combination of Request Sense followed by Test Unit Ready must be repeated until a "good" status is returned on the Test Unit Ready command. A "good" status indicates no errors (current or deferred) are pending.
Controlling image transfer order This section provides job stream examples which can be used in scanning applications. The host application is responsible for determining the order in which the scanner returns images. Front images must always be retrieved before back images. Black and white only duplex 1. Prepare documents. 2. Start the scanner to do black and white duplex scanning (front black and white and back black and white). 3. Setup the scanner to retrieve black and white images. 4.
Dual stream - simplex 1. Prepare documents. 2. Start the scanner to do dual stream simplex scanning (front black and white and front color). 3. Setup the scanner to retrieve black and white images first. 4. Enable the scanner and start polling. Loop Read front black and white image header Read back black and white image Read front color image header Read back color image End loop Dual stream - duplex 1. Prepare documents. 2.
Single-stream duplex alternating between black and white and color/ grayscale using the scanner Toggle patch The Toggle patch is a type 4 patch that is used to trigger the scanner to switch from the current image stream (black and white) to the alternative image stream (color/grayscale). 1. Prepare documents with a patch Type 4 before and after any color/ grayscale documents. 2. Configure image processing parameters for all four images.
Jam and fault recovery This section provides recommendations for application logic associated with scanner jam and fault recovery. If your scanner is enabled and you are polling when a document jam or other fault occurs, use the following procedure to restart scanning. IMPORTANT: Before beginning fault recovery, make sure all the headers and images have been transferred from the image buffer to the host system.
Image file storage locations This section provides general recommendations regarding the impact of image file storage locations on the overall throughput of the scanner. You can receive up to four image files per document. Decisions about where to write these files when retrieving them from the scanner could impact the overall throughput of the scanner. In order to prevent overwriting data the scanner stops feeding paper when the internal image buffer reaches two-thirds capacity.
Starting image address/ next image address The host application must always seed the scanner with the starting image address. The scanner will return the image address associated with each image in the image header. The application can track this image address for use in setting the next image address when restarting the scanner. Indexing schemes Documents are scanned to record the information in an easily accessible form.
Two level indexing When using two level indexing, the image address assigned to each document is defined as follows: • Field D (Level 1) defined as having a field length greater than 0. • Field C (Level 2) defined as having a field length greater than 0.
Two level offset indexing When using two level offset indexing, the image address assigned to each document is defined as follows: • Field D (Level 2) defined as having a field length greater than 0.
Three level indexing When using three level indexing, the image address assigned to each document is defined as follows: • Field D (Level 1) defined as having a field length greater than 0. • Field C (Level 2) defined as having a field length greater than 0. • Field B (Level 3) defined as having a field length greater than 0. • Field A may be defined as fixed field if desired.
Three level offset indexing When using three level offset indexing, the image address assigned to each document is defined as follows: • Field D (Level 2) defined as having a field length greater than 0. • Field C (Level 3) defined as having a field length greater than 0.
Controlling document level changes The previous Indexing Scheme examples illustrated how document levels change within a single group of documents. There are four document image levels: 3, 2, 1, and 0. There are several ways you can set or change the document level: • You can change image address level on the touchscreen. Touching the appropriate Level button increments the image address level to Level 1, Level 2 or Level 3. • You can send a new image address from the host PC.
Level rules Level rules are an automated way to control document image addressing based on the level of the previous document. For a level 3 indexing scheme, the application must define the Level to Follow Level rules for Level 3, Level 2, and Level 1 For example:. Level Level to Follow Level 3 2 2 1 1 1 Level to follow level rules are used to automatically drop to a lower level. Returning to a higher level is generally done through patch or application control of the next image address.
Two categories of performance are provided or each color: Colors that can be completely dropped out and colors that are very close to complete dropout. These values were established by using standard Pantone Matching System® Colors guide (uncoated, 175-line screen). If the background of the document you are using is not bright white the results may vary.

Image header information An image header is associated with every image captured by the scanner. Following is a list of information available in the image header. Image length size of the image. Image identifier indicates whether the image is front black and white, back black and white, front color or back color. Resolution the scanner records the selected scanner image resolution in dots per inch. X-axis upper left pixel horizontal offset to upper left corner of the image.
Image address level (Document level) the document level is assigned by the operator by using: • • • • the level key, a patch if the Patch Reader is enabled, the host application to set the next image address, or the Level to Follow Level rules. The value returned in the image header reflects the level of the document. This value will be level 1, level 2, level 3 or level 0. NOTE: Level 0 is assigned to documents containing patch types T, 1, 4 and 6.
Zone processing Some applications have a requirement to store part of an image in color or grayscale and the rest of the image in black and white format (this saves storage space by not storing the entire image in color or grayscale). Zone processing is a fixed crop window (the zone) located relative to the upper left corner of a document.
Programmable keys Programmable keys are available for use by the operator when the scanner is enabled. The touchscreen displays the functions that are associated with these programmable keys.
Transfer Patch Code The image header reflects when a Transfer patch code is detected on a document. A document containing a Transfer patch is considered to be a Level 0 document. The IA level for the next document following the Transfer patch is assigned to the level (Level 2 or Level 3) that has been previously set. The scanner cannot print on documents containing Transfer patches.
Batching Batching information only applies when the scanner is configured with Image Address enabled via the operator control panel touchscreen. Batching provides a way for the scanner to perform a specific function after scanning a designated number of documents at a particular IA level. Batching can be enabled or disabled through the host software. The host software has control of which level to count and the number of documents to designate a batch.
3 Using the TWAIN Datasource Installation The TWAIN Datasource is included with the scanner. You can install the Datasource from the CD. 1. Insert the CD into the drive. 2. Double-click the setup.exe file. 3. Follow the instructions on each screen as prompted. After installation is complete, install your application software on the host PC. A sample TWAIN Datasource application, called the Scan Validation Tool, is also provided as part of this installation.
Accessing the Scan Validation tool 1. Select Start>Programs>Kodak>Document Imaging>Scan Validation Tool. 2. From the Driver Types box, select TWAIN. 3. From the Drivers box, select Kodak Scanner: i1800 and click OK. 4. Select the Scanner icon. The main Kodak Scanner screen will be displayed.
The TWAIN interface is divided into three main sections: • Image Settings: clicking the Settings button on the main Kodak Scanner window, displays the Image Settings window. From this window you can set your image processing parameters by using the General, Size, Adjustments and Enhancements tab. • Device Settings: the Device button is located on the Image Settings window.
The main Kodak Scanner window The main Kodak Scanner window is the home window of the scanner’s user interface. You can scan by selecting a Setting Shortcut and then selecting OK/Scan. Setting Shortcuts — provides a list of the Setting Shortcuts.
Input document is — allows you to select which sides of the document have information that you want an electronic image of: • Two Sided: scans the front and back of the document. • One Sided - Front: scans only the front side of the document. • One Sided - Back: scans only the back side of the document. NOTES: • Be sure to place your documents face-up in the input elevator. • The Two Sided and One Sided - Back options are only available for duplex scanner models.
OK/Scan — when selected, you will be prompted to save any unsaved changes. NOTE: If this button is OK, any unsaved changes will remain in affect for the current scan session. Cancel — closes the main Kodak Scanner window without saving any changes. Information icons About: displays the scanner’s version and copyright information. Help: displays help information for the window currently being displayed.
The Image Settings window The Image Settings window allows you to define image processing options by using the available tabs. The values used in Image Settings are saved in the selected Setting Shortcut. The Image Settings window includes the following tabs: General, Size, Adjustments, and Enhancements. Side — allows you to select which side and image to configure (e.g., Front, Back: Color (24-bit), etc.). All image settings will be applied to the selected image.
Toolbar buttons Zooms In: enlarges the image that is currently being displayed in the preview area. Zooms Out: reduces the image that is currently being displayed in the preview area. Rotate Outline: rotates the outline 90 degrees. This is only available if the rotated outline will fit in the scanner’s maximum width. Center Outline — adjusts the X origin of the outline such that the outline is centered within the scanner’s maximum width. Preview Quality: selects the quality of the scanned image.
OK/Scan — when selected, you will be prompted to save any unsaved changes. NOTE: If this button is OK, any unsaved changes will remain in effect for the current scan session. Cancel — closes the main Kodak Scanner window without saving any changes. Information icons About: displays the scanner’s version and copyright information. Help: displays help information for the window currently being displayed.
Image Settings - General tab The General tab contains the commonly used image options. In most cases you will not have to change options on other tabs. Scan as — allows you to select the electronic image format. • Color (24-bit): the scanner will produce a color version of your document. • Grayscale (8-bit): the scanner will produce a grayscale version of your document. • Black and white (1-bit): the scanner will produce a black and white version of your document.
Compression — allows you to reduce your electronic image size. • Type: the scanner will produce a color version of your document. - (none): no compression, which may produce a large image size. - Group-4: uses CCITT standard to compress the image, often used in conjunction with TIFF files. NOTE: This option is only available for Scan as: Black and White (1-bit). - JPEG: uses JPEG techniques to compress the image. NOTE: This option is only available for Scan as: Black and White (1-bit).
Image Settings - Size tab The Size tab provides the following options. Document — allows you to select how the scanner will detect your document as it is being fed through the scanner. • Automatically Detect and Straighten: the scanner will automatically find each document (regardless of size) and straighten any document that may have been fed crooked. • Automatically Detect: the scanner will automatically find each document (regardless of size). If a document is fed crooked, it will not be straightened.
Outline — allows you to select the location and size to use for creating your electronic image. The preview area will show the outline. • Origin (x, y): - if you select Document: Automatically Detect and Straighten, (x) is the distance from the left edge of the document and (y) is the distance from the top edge of the document.
Post scan rotation — allows you to select any rotation to be applied to the electronic image after it has been scanned. • (none) • Automatic — the scanner will analyze each document to determine how it was fed and will rotate the image to the proper orientation. NOTES: - There must be a sufficient amount of text on the page for this option to work properly. - This option is designed to work best with Latin-based characters (e.g., English, Dutch, French, German, Italian, Spanish).
Image Settings Adjustments tab The options available on the Adjustments tab depend on the Scan as selection on the General tab. The following options are based on a Scan as selection of Black and White. Conversion quality — these settings effect how the scanner analyzes a grayscale version of the document which is used to produce the black and white electronic image. • Best (iThresholding): the scanner analyzes each document to determine the optimal settings to produce the highest quality image.
Threshold — aids in controlling the level at which a pixel is considered black or white. • Decreasing this setting will make the image appear lighter, and can be used to subdue background noise. • Increasing this setting will make the image appear darker, and can be used to help pick up light information. The options range from 0 to 255. The default is 90. NOTE: This is only available for Conversion quality: Normal and Conversion quality: Draft.
Image Settings Enhancements tab The options available on the Enhancements tab depend on the Scan as selection on the General tab. Blank Image Detection — allows you to configure the scanner to eliminate blank images. • On: turns Blank Image Detection on and makes the rest of the Blank Image Detection options available. • Delete if file size is less than: allows you to select the minimum image size that the scanner will consider to be non-blank.
Advanced Image Setup The Advanced Image Setup is accessed via the icon located next to the Side option at the top of the Image Settings window. When you select the Advanced Image Setup icon, the Advanced tab will be displayed. Done — returns you to the Image Settings window. Information icons About: displays the scanner’s version and copyright information. Help: displays help information for the window currently being displayed.
Advanced tab Input document is — select Two Sided, One Sided - Front, or One Sided - Back depending on what side(s) you want to configure. NOTE: The Two Sided and One Sided - Back options are only available for duplex scanner models. Different settings per side — by default, the settings you select in the TWAIN Datasource apply to both sides of the image. Turn this option on if you want you to select different image processing settings for each side of the document you are scanning.
Images per side — indicates how many images the scanner will create for a side, based on your imaging selections. • One: indicates you want the scanner to create one image. • One - Based on Document Content: indicates you want the scanner to automatically detect if the document is color/grayscale or black and white. • One - Based on Toggle Patch: indicates you want to tell the scanner, via a toggle patch document, if the document is color/ grayscale or black and white.
Refer the examples later in this chapter for procedures on how to configure advanced options. When available, use the up and down arrows to select the order the images will be delivered by the scanner to the scanning application. Toolbar buttons Add: adds an image type to the bottom of the configuration list. Change: allows you to change the currently selected image type. Delete: removes the selected image type. Done — returns you to the Image Settings window.
Content Settings tab The options on the Content Settings tab can be used for either one- or two-sided jobs. Side — determines which side the Sensitivity settings are applied to. This option is only available if Different settings per side is turned on from the Advanced tab. Sensitivity • Low: documents requiring only a small amount of color to be saved as color/grayscale images.
• Custom: allows you to manually adjust the Color amount and/or Color threshold. NOTE: When setting Sensitivity values, it is suggested that you start with the Medium option and scan a typical job set. If too many documents were returned as color/grayscale vs. black and white, then change to the High option and re-run the job. If too few documents were returned as color/grayscale vs. black and white, then change to the Low option and re-run the job.
Creating color/grayscale or black and white images based on the content of your documents In this example, let’s assume you want to configure a scan session that has a mix of color and black and white documents with information on both sides. In addition, you want the scanner to detect whether the page is color or not, and then output either a color or a black and white image based on that. 1. Select a Setting Shortcut from the main Kodak Scanner window that closely describes your desired output. 2.
9. Select Done to return to the Image Settings window. NOTE: You will notice that the Side option now has two entries: Both: Color (24-bit) and Both: Black and White (1-bit). 10. Select Sides: Both: Color (24-bit). Make any other adjustments to the color image settings on the rest of the tabs on the Image Settings window. 11. Select Sides: Both: Black and White (1-bit). Make any other adjustments to the black and white image settings on the rest of the tabs on the Image Settings window. 12.
Creating multiple images for each side of a document In this example, let’s assume you want to configure a scan session that has documents with information on both sides and you want the scanner to produce both a color and a black and white image for each side of each document. 1. Select a Setting Shortcut from the main Kodak Scanner window that closely describes your desired output. 2. Select Settings to display the Image Settings window. 3.
8. Select Done to return to the Image Settings window. NOTE: You will notice that the Side option now has two entries: Both: Color (24-bit) and Both: Black and White (1-bit). 9. Select Sides: Both: Color (24-bit). Make any other adjustments to the color image settings on the rest of the tabs on the Image Settings window. 10. Select Sides: Both: Black and White (1-bit). Make any other adjustments to the black and white image settings on the rest of the tabs on the Image Settings window. 11.
Creating different settings for each side of a document In this example, let’s assume you want to configure a two-sided document stream of business documents that have color on the front of the document but the rear side is fine in black and white. 1. If you are not already on the Advanced tab: • Select a Setting Shortcut from the main Kodak Scanner window that closely describes your desired output. • Select Settings to display the Image Settings window.
The Device Settings window From this window you can set all scanner-specific options, as well as diagnostics, by using the available tabs. The values used in Device Settings are saved in the selected Setting Shortcut. The Device Settings window includes the following tabs: General, Printer, Multifeed, Image Address, Batch, Patch, and OCP. Home — returns you to the main Kodak Scanner window. Image — displays the Image Settings window.
Device - General tab The General tab allows you to set scanner-specific options and provide access to scanner diagnostics. Paper source • Document Feeder: the input elevator is in its highest position. This selection is recommended when you are scanning 25 sheets or less. • 100 Sheets: this selection is recommended when you are scanning between 25 and 100 sheets. • 250 Sheets: this selection is recommended when you are scanning between 100 and 250 sheets.
• Action when timeout occurs: indicates the action that will be taken when the document feeder timeout has been reached. - Stop Scanning: scanning will stop and control will return to the scanning application (i.e. ends the job). - Pause Scanning: scanning will stop but the scanning application will be waiting for additional images (i.e. stops the feeder). Scanning may be resumed by touching Resume on the touchscreen.
Device - Printer tab The Enhanced Printer provides a vertical print capability and supports alphanumeric characters, date, image address, time, document count and custom messages. All print information is captured in the image header of each document. On — turns printing on and makes the rest of the options on this tab available. Level to configure — choose the level of the document that you want the specified print string to be printed on.
Template: Format — allows you to define your print string. The maximum amount of characters for the print string is 40 characters (including spaces). Add — displays a list of items you can add to your print string. When you select an item, that item will appear at the end of the Format list. Change — allows you to change the currently selected item in the Format list with one of the items from the list that is displayed. Delete — allows you to remove the currently selected item from the Format list.
• Date - Format: • • • • • MMDDYYYY DDMMYYYY YYYYMMDD DDD (Julian) YYYYDDD (Julian) - Separator: (the examples indicate a format of YYYYMMDD) • • • • • None Slash: 2007/08/24 Hyphen: 2007-08-24 Period: 2007.08.24 Space: 2007 08 24 - Specific date: allows you to select a specific time if you do not want to use the current date within the scanner. • Time: the format is HH:MM. - Specific time: allows you to select a specific time if you do not want to use the current time within the scanner.
• Orientation: while the characters are printed vertically (starting at the lead edge of the document) this allows you to select the orientation of the print string. Available options are: 0, 90, 180, 270. Feed Direction 0 90 180 270 Offset from lead edge — select a value from 0.35 to 33.5 inches to determine how far the printed information will appear from the leading edge of the document. NOTES: • Printing automatically stops 6.
Device - Multifeed tab Multifeed detection aids in document processing by detecting documents that may go through the feeder overlapped. Multifeeds can happen due to stapled documents, adhesives on documents, or electrostatically charged documents. Ultrasonic detection Sensitivity — controls how aggressively the scanner will work to determine if more than one document is fed into the scanner. Multifeeds are triggered by detecting air gaps between documents.
Sensors — three sensors cover the width of the paper path. In order for multi-fed documents to be detected correctly, they must pass under one of these sensors. • Left, Middle, Right: this allows you to select which sensor(s) you want turned on. For example, if you know that the left side of the document has a “sticky” note on it, you can turn off the left sensor. Length Detection — allows you to select the maximum length of the documents in your job set.
Device - Image Address tab Image addressing is used for document tracking, batch control and image management. The Image Address tab allows you to set an image address starting point. The scanner will increment the image address based on how you set up the image address rules on this tab. NOTES: • This tab is only available when the scanner is in Image Address mode. Current value — displays the scanner’s current image address.
NOTES: • When you make a Format selection, the Field width and Next Level settings will automatically be set to the defaults for that format. • If you made a change to the Field width or Next Level settings, the Format will be appended with the text , and the name will be displayed in italics (e.g., *Level 3 ). • Reset: allows you to undo any changes that have been made to the format. This is only available when you have modified the format (e.g.
Device - Batch tab Batching is the operation of counting pages or documents. NOTE: This tab is only available when the scanner is in Image Address mode. On — turns batching on and makes the rest of the options on this tab available. Level to count — sets the level to count. The options are Level 1, Level 2, and Level 3. NOTE: The level you want to count must exist in the image address template as defined on the Image Address tab.
• Action to take: defines the action to be taken after processing the last document in the batch. - Pause Scanning: scanning will stop but the scanning application will be waiting for additional images (i.e. stops the feeder). Scanning may be resumed by touching Resume on the touchscreen. Scanning may be stopped by touching End Job on the touchscreen or via the scanning application. - Stop Scanning: scanning will stop and control will return to the scanning application (i.e. ends the job).
Device - Patch tab The Patch tab provides choices of what patch type to recognize. One or more patches can be selected at a time. The type of patch recognized is returned in the image header. See the Kodak publication A-61599, Patch Code Information for Kodak Document Scanners for complete information. Patch Confirmation Tone — the confirmation tone may be used to signal that a patch has been recognized by the scanner. The default is no confirmation tone.
Feature • Patch Types 1, 4 and 6 these patch types can be used by the scanning application for post-scan image control (they are not used for image addressing). For example, use these patch types for workflow control or changing between black and white and color/ grayscale imaging. NOTE: This option is only available when the scanner is in Image Address mode. Use Heads — select which patch heads/readers you would like to use. Each patch head/reader can be turned on and off independently.
Device - OCP tab The OCP tab is used to setup options on the scanner’s Operator Control Panel (i.e., touchscreen). Function Keys — available functions for each key are: • (none) • Stop Scanning: scanning will stop and control will return to the scanning application (i.e., ends the job). Restart the scan session from the scanning application. • End Batch: start a new batch by resetting the batch count (i.e. How Many to Count) and continue to scan.
Creating a new Setting Shortcut Setting Shortcuts are separately named and contain all scanner settings required to do a certain scanning job. By default, the i1800 Scanner comes with predefined Setting Shortcuts for the most common scanner tasks. You can use these default Setting Shortcuts or use them as a template to create your own Setting Shortcut. You cannot modify the default Setting Shortcuts. The procedures that follow describe how to configure a customized Setting Shortcut.
3. Select Settings on the main Kodak Scanner window. The General tab of the Image Settings window will be displayed. 4. Select the appropriate options on the General tab. NOTE: If necessary, review each setting on the other tabs and make any changes. 5. Place a representative document in the input elevator. 6. Click Preview to review the resulting image.
Changing Device settings 1. Select the Setting Shortcut from the main Kodak Scanner window that closely describes your desired output. 2. Select Settings to display the Image Settings window. 3. Select Device to display the Device Settings window. 4. Before making any adjustments, browse through the tabs on the Device Settings window to get familiar with features that are available. See the section entitled, “The Device Settings window” for information about these features. 5.
4 Using the ISIS Driver The ISIS Driver is software that communicates with the scanner. This driver is created and maintained by EMC Captiva and is provided with the scanner by Kodak. Many scanning applications support ISIS drivers and this driver can be used to interface with them. This chapter provides descriptions of the options on the tabs of the main ISIS Driver window and how to set these options.
Main tab The Main tab provides the following options: Image Mode Camera — the selections in the Camera box list the available sides (front and back) of an image where you can define individual image processing values. Options include: Front Image #1, Front Image #2, Back Image #1 and Back Image #2. The Kodak Scanner drivers allow you to control the camera settings independently. Some settings apply only to black and white images, others apply to color/grayscale images.
Toggle Patch — the toggle patch is a type 4 patch that is used to trigger the scanner to change from the current image stream (black and white) to the alternative image stream (color/grayscale). This provides color-on-the-fly functionality for customers who want to scan the majority of their documents black and white with the option to switch to color and back when desired. When a toggle patch is detected, this determines the side(s) whose image output is toggled between black and white and color/grayscale.
• Relative to Document (zone processing): used for batches of samesized documents, zone processing is a floating fixed crop window (the zone) located relative to the upper left corner of a document. It allows you to select an area on the document to be delivered in either color/grayscale or black and white format (a separate window for both black and white and color/grayscale may be defined). Different parameters may be selected for both the front and back of the image.
Layout tab The Layout tab provides these options: Image Orientation • Portrait: displays the image orientation in the shape of a conventional portrait, where height is greater than width. • Landscape: displays the image orientation in the shape of a conventional landscape painting, where width is greater than height. Page Orientation — allows you to select the way you place your documents in the scanner, Top edge first, Bottom edge first, Left edge first or Right edge first.
Image Processing tab The Image Processing tab displays the Image Mode, Mode and Toggle Patch information that was previously described. Refer to the section entitled “Main tab” earlier in this chapter for descriptions. General options • Deskew automatically straightens a document within ±0.3 degrees of the leading edge of the document. Deskew can detect up to a 45-degree skew and correct up to a 24-degree angle at 200 dpi or a 10-degree skew angle at 300 dpi.
Noise Filter — select one of the following: None, Lone Pixel or Majority Rule. • Lone Pixel: reduces random noise by converting a single black pixel to white when it is completely surrounded by white pixels or by converting a single white pixel to black when it is completely surrounded by black pixels. • Majority Rule: sets each pixel based on its surrounding pixels. The pixel will become white if the majority of the surrounding pixels are white and visa versa.
Scanner tab The Scanner tab provides the following options. Document Feeder Feeder Position — select the desired paper source. • Normal: select when you are scanning a stack of documents of 25 sheets or less. The input elevator is in its highest position. • 100 Sheets: select when you are scanning a stack of documents between 100 and 25 sheets. • 250 Sheets: select when you are scanning a stack of documents between 250 and 100 sheets.
Timeout On — allows you to select the amount of time the scanner will wait once the last document enters the feeder before the timeout occurs. You can turn this option off or set a time from 1 to 300 seconds. Response — allows you to specify the action that will be taken when the transport timeout has been reached. • End Job: stops the feeder and the transport but leaves the scanner enabled. Scanning may be resumed by touching the Scan button on the touchscreen.
• Low: least aggressive setting and is less likely to detect labels, poor quality, thick or wrinkled documents as multi-fed documents. • Medium: use Medium sensitivity if your Settings Shortcut has varying document thickness or labels attached to the document. Depending on the label material, most documents with labels should not be detected as a multi-fed document. • High: most aggressive setting. This is a good setting to use if all documents are similar in thickness to 20-lb. Bond paper.
Operations Calibrate — displays the Calibrate dialog box which allows you to perform an Image Chain or UDDS calibration. Only calibrate the scanner when prompted to do so. • Image Chain: optimizes your scanner to achieve the best image quality and feeding performance. Frequent calibration is not necessary or recommended. • UDDS: ensures that the ultrasonics system that detects multi-feeds and document edges is properly adjusted for best performance.
Use the calibration target provided with your scanner. 1. Click Calibrate. The Calibrate dialog box will be displayed. 2. Select Image Chain or UDDS from the drop-down box. • If you select Image Chain, use the calibration target provided with your scanner. Be sure to use a good, clean calibration target. Place the calibration target in the input elevator face up and click OK.
Auto Color Detect tab The Auto Color Detect tab provides the following options. Color Content Select one of the following options for automatic color detection. • Low: documents require only a small amount of color to be saved as color or grayscale images. Used for capturing documents that are primarily black text with small logos, or contain small amounts of highlighted text or small colorful photos.
Color Amount: the amount of color that needs to be present in a document before it will be saved as either color or grayscale. As the value of Color Amount increases, more color pixels are required. Valid values are 1 to 200. Color Threshold: the color threshold or intensity (i.e., pale blue vs. dark blue) at which a given color will be included in the color amount calculation. A higher value indicates that a more intense color is required. Valid values are 0 to 100.
Dropout tab The Dropout tab displays the Image Mode, Mode and Toggle Patch information that was previously described. Refer to the section entitled “Main tab” earlier in this chapter for descriptions. Color Dropout Color dropout is used to eliminate a form's background so that only the entered data is included in the electronic image (i.e. remove the form's lines and boxes).
Imprinter tab The Enhanced Printer provides a vertical print capability and supports alphanumeric characters, date, image address, time, document count and custom messages. All print information is captured in the image header of each document. Mode • Do not print: disables the options on the Imprinter tab. • Print on the front of document before scanning: enables the options on the Imprinter tab. Level — choose the level of the document that you want the specified print string to be printed on.
Defining your print string Format Template — allows you to define your print string. The maximum amount of characters for the print string is 40 characters (including spaces). Date — if you want to add a date to the print string, select one of the following formats: • Format: MMDDYYYY, DDMMYYYY, or YYYYMMDD. • Delimiter: select one of the following separators: Slash: /, Hyphen: -, Period: . , Blank or none. For example: 08/24/2007, 08-24-2007, 08.24.2007 or 08 24 2007 or 08242007 (none).
Image Address tab Image addressing is used for document tracking, batch control and image management. The Image Address tab allows you to set an image address starting point. The scanner will increment the image address based on how you set up the image address rules on this tab. Format String — this text field allows you to structure your image address. Fixed field information entered in this field will be reflected in the Image Address area in Fields A through D.
Image Address fields — displays the starting image address. The values in this field reflect information from the Format String area and the Start Value field in the Counters area. Each field can have a maximum width of 9 characters. The total image address cannot exceed 27 characters (30 with 3 delimiters). Presets — you can use the selections in the field to automatically fill in the format string field. The options are: • Custom: enter your desired values.
Batch/Patch tab The Batch/Patch tab provides batch and patch functionality. Batching is the operation of counting pages or documents. The Patch tab provides choices of what patch type to recognize. One or more patches can be selected at a time. Batch Control The batch function allows you to define the level to count the number of documents in the batch and any actions to be taken at the beginning and end of a batch. On — enables batch separation.
Patch Detection Patch Control allows you to select what patch types to recognize. One or more patches can be selected at a time. On — check this box to enable patch recognition. Image Address Patch Codes — these patch types are used for image addressing. When the Patch Reader detects a patch, it automatically assigns a new image address to the new document. This eliminates the task of trying to determine where one document stops and the next starts when an operator is viewing electronic images.
Feature Patch Codes — these patch types can be used by the host for post-scan image control (they are not used for image addressing). For example, use these patch types for changing between black and white and color/grayscale imaging or workflow control.
OCP tab The OCP tab is used to assign actions the operator uses from the Operator Control Panel. Function Key #1, Function Key #2 and Function Key #3.
Operator Log tab The Operator Log tab provides a listing of any errors that have been encountered. You can either save this information to a file by clicking the Save icon, or click the Copy icon to copy the information to the clipboard. About tab 4-24 Displays information about your scanner and driver.
Scan Area dialog box The Scan Area dialog box is only available for images when the Cropping option selected on the Layout tab is either Fixed to Transport or Relative to Document. To access the Scan Area dialog box, select Scan Area on the Layout tab. NOTE: Select the side and image to be defined by highlighting Front Image #1, Front Image #2, etc. based on the cropping option selected for each of these on the main ISIS Driver tab. The scan areas defined for all camera selections are independent.
Area • Snap causes the dimensions of the Area box to be controlled in fixed 1/8-inch increments. This option is not available in Pixels mode. • X: the distance from the left end of the scanner to the left-edge of the scanning area. • Y: the position from the top end of the document to the top end of the scanning area. • Width: the width of the scanning area. • Height: the height of the scanning area. Units — select whether you want the area to be defined in Pixels, Inches or Centimeters.
