2. SCANNER INSTALLATION 2.1 PRECAUTIONS v Keep the scanner out of direct sunlight. Direct exposure to the sun or excessive heat may cause damage to the unit. Do not install the scanner in a humid or dusty place. Be sure to use the proper AC power source. Place the scanner securely on an even, flat surface. Tilted or uneven surfaces may cause mechanical problems. Keep the shipping box and the material in case you may need to ship the scanner again.
2.2 UNLOCKING YOUR SCANNER To protect the scanning unit from damage during transportation, a lock switch is designed under the scanner to keep the scanning unit from moving.To unlock the scanner, please first place the scanner as Fig. 2-1 and locate the lock switch at the corner and then move the lock switch to the “Unlock” position as shown in below.
2.3 SETTING SCSI ID When you have several devices on a SCSI chain, you may have to adjust the SCSI ID selector setting at the back of the scanner(See Figure 2-2). This setting assigns a specific "device ID" to the scanner. If the ID number is duplicate with an existing SCSI device on the SCSI chain, please select a new ID#. Note: The factory setting for the scanner is ID# 6. Usually, ID# 0 is assigned to an internal hard disk drive, and ID# 7, to SCSI adapter or host. ID# 8 and #9 are not in use. 2.

4. SCANNER OPERATION AV620CS Plus allows you to operate the scanner from within a TWAIN or plug-in software application. As the scanner driver is not a stand-alone software, it has to be started from within a TWAIN*compliant software application and then the scanner driver is able to scan and load the image to your computer. The command to start the scanner driver may vary due to different software applications. To check the correct command, please refer to the user manual of your software application. 4.
3. 4. 5. The Mac Plug-in user interface will pop up on the screen. Place the document upside down on the document glass with the text facing away from you. Click the Preview or Scan button to preview or scan your document or image. Figure 4-1 Mac Plug-in user interface *TWAIN: Stands for Technology Without An Interesting Name, an industry-standard protocol which exchanges information between the application and image acquisition device such as scanners.
PC Users 1. Open your application and choose Select Source from the File menu. If the Select Source command is not available from the File menu, see the user guide of your application to learn how the TWAIN link is used. 2. A dialog box appears containing the different TWAIN sources for you to choose from to bring an image into your application.
Select MrScan-Expert as the source. 3. You need to select MrScan-Expert for just once except when you need to use the dialog box to select a different source. In that case, you will need to select MrScan-Expert as the source again before you can reuse the scanner. 4. Place the document upside down on the document board with the text facing away from you. 5. 6. From the File menu, choose Acquire. Avision TWAIN user interface as Figure 4-2 will pop up on the screen.
4.2 USING AVISION SCANNER DRIVER USER INTERFACE 4.2.1 CHOOSING YOUR SCANNING SOURCE Two scanning sources are provided - flatbed as well as transparency. However, if you have not installed the transparency kit, please leave the source to the flatbed option.
4.2.2 DETERMINING YOUR RESOLUTION A good control of the resolution results in a satisfactory detail of an image that scans. The resolution is measured by dots per inch(dpi). Normally, the greater the dpi number, the higher the resolution and the image file size. Be aware that the greater resolution takes more time, memory and disk space;therefore, up to a certain degree of dpi, the resolution will not visually be improved, and on the contrary, it makes your files more unmanageable.
Tips: 1. For your information, an A4 size color image scanned at 300 dpi at True Color mode consumes approximately 25 MB of disk space. A higher resolution (usually means over 600 dpi) is recommended only when you need to scan a small area at True Color mode. 2. You can also refer to the following table to choose a proper resolution while applying your image to other application.
4.2.3 SELECTING A PROPER IMAGE TYPE Select image type through the mode from the scanner user interface for your own purpose.
Each image type is described as follows: Line art LineArt presents the image in black and white only and there are no intermediate shades of gray in between. That means each pixel of the image is 100% black or 100% white. LineArt is the best choice of image type if you want to scan text, pen or ink drawing. Since only 1-bit of black or white information is required for each pixel*, the disk space required for saving lineArt image is only about 1/24 of that required to save 24-bit true color images.
Halftone In addition to the black and white display, Halftone simulates grayscale by using different size of dots. Particularly when you view the image at a certain distance, it looks very closely like a gray image yet it consumes the least disk space. Halftone is the picture that we usually see in newspapers or magazines. Since Halftone is one type of black and white image, the disk space required to save a halftone image is 1/24 of that required to save a 24-bit true color image.
Gray (4096 levels gray scale/Internally) Usually, a single-channel image consists of at least 8-bit or 256 levels of shades of gray in an image. However, AV620CS Plus with 12 bits produces a Gray image with 4096 shades of gray between pure black and pure white. Gray is the best choice of image if you wish to scan a black and white photograph.
True Color A 36-bit Color image consists of three 12-bit color channels. The red, green, and blue channels are mixed together to create 36 a combination of more than 6.8billion(2 ) colors which give a more true-to-life quality to the image. True Color is the best choice if you want to scan a color photo.
4.2.4 ENHANCING YOUR IMAGE Brightness Contrast Gamma Highlight Shadow Hue Intensity Saturation Brightness: Adjusts the lightness or darkness of an image. The higher the value, the brighter the image.
Contrast: Adjusts the range between the darkest and the lightest shades in the image. The higher the contrast, the bigger the different gray scales. Decrease your Contrast Gamma: Gamma Value: 1.0 4-14 Normal Increase your Contrast Adjusts the midtone of the image without losing details of the lightest and the darkest areas. Gamma Value: 1.4 Gamma Value: 2.
Highlight/Shadow: Highlight refers to the lightest point in a scanned image while shadow refers to the darkest point. Using Highlight and Shadow tool together allows you to extend the range of color and reveal more details in a gray or color image.
Hue: Adjust the hue up to 360§ by clicking your desired color on the Color wheel or clicking the up or down arrow button. (Note the level of intensity for the color will be changed simultaneously when the hue adjustment is made). The Color Wheel Intensity: Adjust the color strength by clicking the Up or Down arrow button. Saturation: Adjust the saturation level for the color by clicking the Up or Down arrow button. The level of saturation decides if the color is pale or rich.
Speed Mode Advance Settings Auto Crop Invert Image Color Matching Quality Mode Advance Settings: (PC) Click the button and a dialog box in below will be displayed. This dialog allows you to remove one of the R(Red), G(Green), or B(Blue) color channel while scanning. For example, if your image contains red color text or red color background, choose the R(Red) channel then any text or background in red color will be removed. Yet this function supports only black & white and gray image.

Invert Image: The invert command reverses the brightness and the color in the image. For color images, each pixel will be changed into its complementary color at the command of Invert.
Color Matching: Adjusts the color quality of the image so that it comes close to that of the original. This function uses default parameters to adjust the image. Before Color Matching After Color Matching Quality/Speed Mode: Choose Speed Mode if you need to speed up your scanning task. Choose Quality Mode if you need a better quality of your scanning result.
Auto Level: (Mac) Automatically adjusts the highlight and shadow areas of the scanned image to give it an optimal effect. Before Auto Level Auto Crop: After Auto Level Automatically sets the whole document as the scan area, no matter what its size.

6. TROUBLESHOOTING The scanner will automatically perform a simple self-test each time it is turned on. This will help to spot major system errors in the scanner itself. When the test is initiated, the READY LED is flashing. When the test is completed, the READY LED is steadily on. If you have problems with the operation of your scanner, please check the following troubleshooting hints. 6.
Question: When the scanner is powered on, it makes noises and won’t stand ready. Answer: There are two possibilities: 1) You might fail to push the scanner shipping lock to its “use” position. If this is the case, pull the scanner status switch to its “use” position first. 2) The scanner is not placed on an even, flat desktop surface. This may cause the scanner to malfunction. Question: The scanner is powered on, but the lamp does not light up. Answer: The lamp is probably out of order.
Question: While scanning, the scanner often makes noises, or it scans back and forth. Answer: Usually this means the memory of your computer is not enough or the speed of your CPU too slow. Please try to increase your memory to at least 32M or replace your CPU with Pentium or later. Question: Why is it that the scanned image always comes out to be too dark? Answer: 1) Modify the Gamma setting to1.8~2.2 for your monitor and, when printing, set the Gamma setting to 2.2 for your printer.
