2 Getting Started The following steps are necessary to prepare the scanner for operation. Procedures on how to perform these steps are described in this chapter. 1. Turn on the power to the scanner. 2. Select the language display. 3. Calibrate the scanner. 4. Prepare the documents for scanning. 5. Adjust the feed and separator roller gap, if required (semi-automatic feeder). 6. Adjust the feed shelf position. 7. Adjust the feed shelf side guides. 8. Adjust the exit hopper side guides and end stop. 9.
Selecting the language display The scanner may have been configured at installation to allow use of a second language in the status display. The language used (French, German, Italian, Spanish, or other) is defined during installation. If available, the alternate language display may be accessed using function code F19. Calibrating the scanner Calibration sets the intensity of the lamps, which contribute to the overall quality of the scanned document image.
Unsuccessful calibration If calibration is not successful, a message appears in the status display. You may need to: • Verify you are using a clean, blank sheet of paper (at least 12 inches in length) as a calibration target. The paper must be wider than the documents being scanned and at least 8 1/2 inches long. • Verify there is not a document already in the document path. (Refer to the section entitled, “Clearing the document path” in Chapter 7.) • Clean the imaging guides.
Adjusting the feed and separator roller gap (semi-automatic The gap adjustment knob on the control panel increases or decreases the space between the feed and separator rollers. The gap must be adjusted properly for smooth transportation of documents without document overlap. feeder) When documents of different thicknesses are fed in a group, adjust the gap using the thinnest document in the group.
4. Press Run. 5. Select two documents of the same size, texture and thickness, similar to the types of documents you will be scanning. 6. Place one document on top of the other. Hold the documents firmly by their trailing edges. Insert them into the gap approximately 1/8 in. (3 mm). Bottom document separates from top document 7. If the documents separate, repeat the following steps until the documents do not separate: • Turn the gap adjustment knob clockwise 1/2 turn. • Insert the documents again.
13. Enter F04 and disable Counting only. 14. Press Enter.

For automatic feeding, raise the feed shelf to the 30° or 40° position. 40° position Adjusting the side guides 30° position Before you begin feeding documents into the scanner, adjust the position of the side guides and feed shelf position. • Adjust the width of the feed shelf side guides to hold the widest document you will be scanning.
Adjusting the exit hopper side guides and end stop The exit hopper side guides and end stop must be adjusted so documents are stacked properly. 1. Adjust the exit hopper side guides to hold the widest document you will be scanning. Leave ¼-inch (5 mm) clearance on each side of the document. 2. Adjust the end stop to hold the longest document you will be scanning. An end stop extension is included to accommodate documents up to 17 inches in length.
3. Adjust the height of the exit hopper so the scanned documents naturally fall between the exit hopper side guides and exit hopper end stop.
3 Operating the Scanner Overview This chapter provides instructions for selecting modes, image level settings and feeding documents using the semi-automatic feeder and the automatic feeder. The scanning process consists of the following steps: 1. Prepare the scanner for operation (refer to Chapter 2, Getting Started for more information). 2. Select an application mode for the application. 3. Select the appropriate operating values required for the application on the host computer. 4. Press the Run key.
Setting image levels Image levels are used to identify specific types of documents (or sets of documents) for later indexing and retrieval. The image level assigned to each document is inserted into the image header associated with the document image. There are four document image levels: • • • • Level 0 Level 1 Level 2 Level 3 Setting Levels Levels 1, 2, and 3 can be set by pressing a document Image Level key on the control panel, or by using the optional Footswitch or Patch Reader accessories.
Temporary operating values Each of the 18 modes programmed at the time of installation contain definitions that affect the output of the scanner. Each mode is programmed to conform to the output requirements of a particular application or group of applications. There may be instances, however, when a particular application requires some variation of an existing mode. In such instances, mode definitions may be changed using available function codes.
Feeding documents using the semiautomatic feeder Following are feeder instructions using the semi-automatic feeder. After the scanner has been prepared for operation, the desired mode and any temporary operating values have been defined, you are ready to feed documents into the transport. 1. Verify that the power is on and that all of the proper adjustments have been made (feeder side guides, exit hopper side guides, etc.). 2. Place the feed shelf in the Up position. 3.
7. As you scan documents, set the image level, as required, and periodically remove documents from the exit hopper. NOTE: When the image buffer is full, the feeder will turn off and the image buffer status light will turn red. There may be a momentary pause in scanning while images are being transferred to the host computer. Scanning will resume and the status indicator will change to green when the image buffer is clear. 8.
Feeding thick documents The gap release lever is used to feed thick documents such as card stock or cover stock. The lever is located on the front panel of the scanner next to the gap adjustment knob.

8 Accessories This chapter provides a list of available accessories for the Kodak Digital Science Document Scanner 7520. Operating instructions for most of these accessories can be found in this chapter. Other accessories are available but do not necessarily require any specific operating instructions. Any operating instructions you receive on new accessories can be conveniently placed in this chapter so you can easily access them as needed.
Parts and tools The following parts and tools are needed to properly maintain your system. NOTE: Field Engineers/Specialists are not authorized to order these items; they should be ordered by the customer.
Using the Bar Code Reader The Kodak Digital Science Bar Code Reader provides a hands-off method of data entry, eliminating the need to manually enter data found on document(s). Bar code image(s) are read, decoded, and converted to a data string of ASCII characters. The ASCII data string is placed in the image header which is sent to the host computer when scanning, or merged with the document image address and transmitted as a data record to a host computer for storage in a data library when filming.
Bar code types During installation, the type of bar code used is defined for each mode. The Bar Code Reader is capable of reading and decoding three different types of bar codes. • Code 3 of 9 — also known as Code 39, is a widely used code in which 9 bars or spaces comprise the characters, 3 of which are wide. • Interleaved 2 of 5 — or I 2 of 5, is a compact, interleaved code for numeric characters only. Each digit is represented by 5 bars or spaces, 2 of which are wide.
Bar code placement Bar codes must appear with the bars perpendicular to the leading edge of the document: Leading edge (fed into transport first) Trailing edge In addition, the following must be true: • The bar code must be at least 0.25 in. (6.3 mm) from the leading edge of the document. • The bar code must be at least 0.25 in. (6.3 mm) from the trailing edge of the document. • There must be at least 0.25 in. (6.3 mm) of blank space preceding the start character and following the stop character.
Enabling bar code reading Make sure that Bar Code Reading is enabled before feeding documents. To enable Bar Code Reading at the mode level: • Enter function code F60. If you have enabled the Bar Code Reader, but do not want to read/decode bar code(s) found on the next document only, perform function code F64. Enabling the bar code confirmation tone The bar code confirmation tone may be used to signal that a bar code has been read.
Performing a bar code test Before feeding documents, perform a bar code test (F65) to verify the operation of the Bar Code Reader. NOTE: No document processing, image address changes or level counting, etc. will occur during the test. To perform a bar code test, select one of the test options. 1. Enter function code F65. 2. Select one of the following options.
Function code F65 options may also be used if there is a decline in bar code readability (read rate) during normal document processing. If this occurs, the following steps will assist you in diagnosing the problem: 1. Perform test option 3=Read Rate. This test determines whether or not the reduction in readability is caused by a deficiency in the equipment. − If the resulting read rate is significantly lower than the benchmark given, contact Service.
4. Lift the release bar to raise the front scan module. 5. Lift up and latch the horizontal transport plate into its open position. NOTE: If the Patch Reader accessory is installed, the Patch Reader must be removed from the mounting plate in order to lift up the horizontal transport plate. 6. Open the side access door. Do not leave the side access door open for more than 5 minutes.

You can change a document image level or perform a commonly used function simply by pressing, pressing and holding, or releasing the Footswitch. During installation, modes are defined for use with specific applications.
Footswitch Pressed Definition Footswitch Released actions Sustained Level 0 All documents fed into the transport while the Footswitch is pressed and held are assigned Level 0. Sustained Level 1 All documents fed into the transport while the Footswitch is pressed and held are assigned Level 1. Sustained Level 2 All documents fed into the transport while the Footswitch is pressed and held are assigned Level 2.
Using the Patch Reader The Kodak Digital Science Patch Reader controls document level changes by automatically sensing a pre-defined patch code and changing the document level accordingly. During installation, modes are defined for use with specific applications. Patch reading may be enabled or disabled for each mode. Patch types During installation, the patch type(s) used are defined for each mode. The Patch Reader is capable of reading three types of patches.
Patch code placement Patches may appear parallel to the leading edge of the document: Leading edge (fed into the transport first) In addition: • The top of the patch must be more than 0.20 (5 mm) and less than 0.80 inches (20 mm) from the leading edge of the document. • The bottom of the patch must be no more than 1.6 inches (40 mm) from the leading edge of the document. • There must be at least 0.20 inches (5 mm) of clear space surrounding the patch on all sides.
Patch Reading function codes The following function codes can be enabled (or disabled) when using the Patch Reader accessory. Enabling patch reading — make sure patch reading is enabled before feeding documents. • Patch reading may be enabled or disabled at the mode level using function code F50. Enabling the patch reading confirmation tone — the patch code confirmation tone may be used to signal that a patch has been read.
Changing the horizontal read position The horizontal read position is set by placing the Patch Reader in one of the five reader positions on the mounting plate. NOTE: The five Patch Reader positions are also indicated with a patch mark on the label on the feed tray. The Patch Reader is attached to the mounting plate by magnets. To change the position of the Patch Reader: 1. Lift the Patch Reader off the mounting plate and place it in one of the other four available positions. 2.
Using the Document Printer The Kodak Digital Science Document Printer is capable of printing customer-specified information on customer documents. Front and/or rear printers are available.

Appendix A Basic Concepts This appendix provides the basic concepts associated with scanning documents. Modes The scanner offers 18 modes that can be defined for a particular application or group of applications. When you select a mode for use with a particular application, you are selecting the format/appearance of the output. Each mode is comprised of definitions that affect the output of the scanner. Required mode definitions include index format, level to follow level rules, etc.
Image addresses An image address is assigned to every document scanned. An image address is composed of four fields, each representing a different document level. An image address has a maximum length of 15 characters; 12 alphanumerics (field A, field B, and field C must be numeric; the fixed field may contain alphanumerics) and 3 delimiters (inserted between fields).
Assigning an image address An image address may be assigned or changed by pressing the Next key or by entering function code F97. The Next key (or function code F97) is used when setting/changing any or all of the image address fields. Function code F92 is used when setting/changing only the fixed field of the image address. Using the Next key Press Next (or enter function code F97) to set or change an image address function code. The next image address is displayed.
Using Function Code F92 Function code F92 allows you to set or change the image address fixed field. The number of characters in the image address fixed field is defined during installation for each mode. Using F92, you will not be allowed to enter more than the predefined number of characters. The fixed field of the image address will be displayed. An entry cursor will appear over the first character of the fixed field.
8. Use the Left or Right arrow key to position the flashing cursor over the letter E. 9. Press Enter to place the letter E in the second fixed field character position. The letters DE appear in the display, with the entry cursor appearing in the next character position. 10. Press the Up or Down arrow key to enter alpha entry mode. 11. If the letter C is not displayed, press the Up or Down arrow key until it is displayed. 12. Use the Left or Right arrow key to position the flashing cursor over the letter C.
Single level indexing When using single level indexing, the image address assigned to each document is defined as follows: • Field A (Level 1) is defined as having a field length greater than 0 • Field B (Level 2) is defined as having a field length of 0 • Field C (Level 3) is defined as having a field length of 0 • Fixed field may be defined, if desired For example, if you scan a book with 50 pages, the image address has been defined: • Field A has a field length of 3 characters • Field B has 0
Two level indexing When using two level indexing, the image address assigned to each document is defined as follows: • Field A (Level 1) is defined as having a field length greater than 0 • Field B (Level 2) is defined as having a field length greater than 0 • Field C (Level 3) is defined as having a field length of 0 • Fixed field may be defined, if desired For example, if you scan a book with 2 chapters (Chapter 1 has 40 pages and Chapter 2 has 60 pages) the image address has been defined: • • •
Two level offset indexing When using two level offset indexing, the image address assigned to each document is defined as follows: • Field A (Level 1) is defined as having a field length of 0 • Field B (Level 2) is defined as having a field length greater than 0 • Field C (Level 3) is defined as having a field length of 0 • Fixed field may be defined, if desired For example, if you scan a book with 2 chapters (Chapter 1 has 40 pages and Chapter 2 has 60 pages), the image address has been defined: •
Three level indexing When using three level indexing, the image address assigned to each document is defined as follows: • • • • Field A (Level 1) is defined as having a field length greater than 0 Field B (Level 2) is defined as having a field length greater than 0 Field C (Level 3) is defined as having a field length greater than 0 Fixed field may be defined, if desired For example, if you scan a book with two sections (Section 1 contains 2 chapters, each having 40 pages; Section 2 contains only 1 chap
Three level offset indexing When using three level offset indexing, the image address assigned to each document is defined as follows: • • • • Field A (Level 1) is defined as having a field length of 0 Field B (Level 2) is defined as having a field length greater than 0 Field C (Level 3) is defined as having a field length greater than 0 Fixed field may be defined, if desired For example, if you scan a book with two sections (Section 1 contains 2 chapters, each having 40 pages; Section 2 contains only 1
Controlling document level changes The previous Indexing Schemes examples have illustrated how document levels change within a single group of documents. There are four document image levels: 3, 2, 1, and 0. There are a number of ways in which you can set or change the document level: • You may press a document level key on the control panel to assign a document Level 3, 2, or 1. • You may use function code F07 to assign a document Level 0.
Special considerations Checking the meters It is useful to check the meters to determine maintenance schedules and the length of time required to complete a job. To view the run time display, enter function code F17. The display shows three meters: • • • Meter A shows the number of motor-on hours Meter B shows the number of transport-on hours Meter C shows the number of AC-on hours Press C (Clear) to clear the display.
