Control Menu
   Control Menu Box

   Click this box to display the Control menu. Use the commands in the Control menu to move or close the ScanMan window. The About menu item in the Control menu displays copyright information and version number for your Logitech ScanMan software. To close the ScanMan window, double-click the Control-menu box.


   Title Bar

The title bar displays the name of the application. To move the ScanMan window, position the cursor on the title bar and drag.


Preview Window
   Preview Area

This large area in the ScanMan Window is where you see an image display as you scan, unless you have disabled Scan Preview mode in the ScanMan Options dialog box.

We recommend that you glance at this area while scanning to check your progress.

As you scan, the image scrolls in the Scan Preview area according to the current Scan Preview mode selected.

The way an image appears in the Scan Preview area depends on the Document Mode you've selected, your computer's graphics adapter, and your scanner model.


   Speed Indicator

The Speed Indicator in the ScanMan Window displays your scanning speed in lines per second. As you scan, glance occasionally at the Speed Indicator to see whether you're scanning at the right speed to capture the image. The Speed Indicator also lets you know how fast you can scan without exceeding the limit.

OK (green). Green indicates that your scanning speed is okay.

Caution (yellow). Yellow indicates that your scanning speed is almost too fast. If you do not slow down, your image may lose data or lines. If you enable the Audible Speed Warning option in the ScanMan Options dialog box, the software produces a beep when you enter the yellow zone.

Too Fast (red). Red indicates that you're scanning too fast for the computer to capture all the data. You may lose image data and you may have to rescan the image.

If you have a 16-color, standard VGA display adapter and you have enabled the Use VGA Palette option in the File menu Preferences dialog box of both FotoTouch Gray and FotoTouch Color software, the ScanMan window and the Speed Indicator will display in gray.


Width Ruler
   Adjusting the Scan Width Ruler

The Scan Width ruler, located along the top of the Scan Preview area in the ScanMan Window , determines the width of the scan strip. This example shows that the scanner will scan a strip 2 3/4 inches wide.

You can adjust the scan width to crop an unwanted area of an image as you scan. Use the margin sliders to adjust the Scan Width ruler from either side. Use your mouse or pointing device to drag a margin slider.

The current scan width appears in gray on the Scan Width ruler; the scan margin appears in white. The ruler uses the unit of measure you select from the International Measurement settings in the Windows Control Panel.


   Status Area

The Status area in the ScanMan Window tells you the current status of the software and what you need to do next.

Scanning messages. A Status area message tells you when the software is ready for you to scan a single strip, the first strip of a multiple-strip scan, or an additional strip in a multiple-strip image.

Resolution setting. If your scanner has a resolution switch, a Status area message reminds you to change the setting on the scanner if you change it in the Scanner Setup area.

Document mode setting. A Status area message reminds you to change the document mode setting on the scanner when you change it in the Scanner Setup area.

   Calibrate

The Calibrate button in the Options dialog box displays the ScanMan Calibration dialog box with instructions to help you calibrate your scanner.

Calibration ensures the best results when you scan an image in Gray or Color document mode, and it may contribute to good results when using AutoStitch. Calibration ensures the scanner's ability to reproduce shades evenly and consistently across a scan strip, minimizing shade variation.

When you calibrate your scanner, the software saves the results as a calibration map. When you click the Done button after scanning a continuous-tone image, the software automatically calibrates the image. The software tells you what to do during calibration.

You should use the supplied calibration card to calibrate your scanner. Cover the entire card with the scanner. Keep the card clean and be sure that the plastic window under the scanner is dust-free. This will prevent streaks in your scanned images. Remove any dust with a lint-free cloth.

Recalibrate your scanner when you see vertical streaks, or when you notice that the shades of multiple strips vary, causing stitch lines.

Preview Mode
   Scan Preview Mode

The Scan Preview mode options in the Options dialog box determine how an image displays in the Scan Preview area as you scan. To choose a Scan Preview mode, click one of the option buttons. A dot appears in the current option button. You can only choose one option at a time.

Scroll

As you scan, this mode displays an image from the top to the bottom of the Scan Preview area. It scrolls the image up when the display reaches the bottom of the area. The Scroll mode provides the most realistic display of an image. However, the software takes longer to display image data in this mode. Use the Scroll mode only if your system's processing and video speeds are capable of keeping up with the incoming image data.

Sweep

This is the default Scan Preview mode. As you scan, the image displays from the top to the bottom in the Preview area. When the image fills the area, it displays from the top again. You should use the Sweep mode for most computers because it displays image data faster than the Scroll mode.

Off

This option turns off the software's ability to display an image as you scan. Use this option if you have a computer with slow processing speed. You'll see the image in the application after you click Done.

Speed Warning
   Audible Speed Warning

The Audible Speed Warning check box in the Options dialog box enables and disables the Audible Speed Warning option. Audible Speed Warning causes your computer to beep when you begin scanning too fast for the software to accept the image data. Audible Speed Warning is enabled by default, and an X appears in its check box. To disable Audible Speed Warning, click its check box. The X disappears.

The beep sounds when your speed goes into the Caution (yellow) zone in the ScanMan window's Speed Indicator. There is no distortion at this speed, but it's easy to slip into the red zone and distort your image.


ScanMan Setup

The ScanMan Setup dialog box prompts you to select one of three setup options:

1) installing the EasyTouch scanner on a parallel port

2) installing a ScanMan scanner with a bus interface card

3) installing new software for a previously installed ScanMan scanner.

The EasyTouch scanner plugs into a parallel port on your computer without requiring any hardware cards to be added.

Installing a ScanMan scanner with a bus interface card requires opening your computer and adding a printed circuit board in an expansion slot. ScanMan scanners that use a bus interface include ScanMan Color, ScanMan 256, ScanMan 32, ScanMan Plus, and ScanMan.

If you are only upgrading the software for a scanner that has been in use, the third option loads the new software without requiring any hardware setting changes.


Hardware Setup

Click a box or button for help

The Hardware Setup dialog box displays the current hardware settings.

If you're installing ScanMan software, and your scanner is specified, click the Test button to test your settings. If the test is successful than click OK.

If the Test button is dimmed, choose a new I/O address to match the address on your scanner board. Then click the test button. If the Test button is still dimmed, try the other  I/O addresses.

If Test is still unavailable, you probably have an I/O address conflict. Refer to the ScanMan Installation Guide for information about setting the I/O address.


Interface

The Interface drop-down box allows you to choose where to connect your scanner to your computer. Click the down arrow to view available options.

If your scanner is connected to a scanner controller board, select Bus Card. If your scanner is connected to your computer's parallel port (LPT1, 2 or 3), select Parallel Port.


Scanner Model

The Scanner Model drop-down list box displays the name of the scanner connected to the ScanMan controller board installed in your computer. If you have a ScanMan 256, ScanMan Color, or ScanMan EasyTouch scanner, the software automatically detects them when connected to the controller board or parallel port.

If you have a black-and-white scanner, such as the Logitech ScanMan Model 32, ScanMan Plus, or ScanMan, the software cannot detect the model of scanner you have connected to the controller board. Therefore, the Scanner Model list box displays a list of possible scanners. To select your scanner, click the drop-down arrow and select the appropriate name.

"No Scanner Detected" appears in the Scanner Model list box if your scanner isn't attached to the controller board or if the ScanMan software can't detect your scanner for another reason, for example, if you have chosen a Board Base I/O Address that doesn't match the current address on your controller board.


Board Base I/O Address

The Board Base I/O Address is the input/output address used by the software to communicate with the scanner controller board. The available address are 280H (hexadecimal), 2A0H, 330H, and 340H. The default address is 280H. You should use the default address unless you know that the scanner controller board conflicts with another board, such as a network adapter, installed in your computer.

If the I/O address displayed here does not match the address set on your scanner board, the Test button will be dimmed.

If a picture of your scanner board appears in the Setup dialog box, then the picture represents the current I/O software address settings.


DMA Channel Number

The scanner controller board uses the DMA (Direct Memory Access) Channel Number to transfer an image to the computer's memory. The default DMA channel number is 3. Use any valid DMA channel that doesn't conflict with DMA channels used by other devices in your computer. To select an available DMA channel number, click the drop-down list box arrow and select an available channel number.


Interrupt Request

The scanner controller board uses the Interrupt Request (IRQ) to signal the computer's central processing unit (CPU) that digital image data is ready for transfer to memory. The default IRQ is 11. Use any available IRQ that doesn't conflict with IRQs used by other devices in your computer. To select an available interrupt, click the drop-down list box arrow and select a number.

The scanner controller board only uses IRQs 3, 4, 5, and 7 if you have an IBM PC/AT and you have installed the scanner controller board into an 8-bit instead of a 16-bit expansion slot. The controller board also uses these IRQs if you have an earlier version of the board with jumper pins. If your scanner controller board has jumper pins that are not currently set, you need to set a jumper for the IRQ.


Test

Click Test in the Hardware setup dialog box to display the ScanMan Test Procedure dialog box. This dialog box provides instructions for testing your scanner to ensure that the hardware settings you've chosen in the ScanMan Hardware Setup dialog box work properly.

Follow the instructions. If the test is successful click OK. If the test is not successful, on-screen error messages will recommend changes to your hardware settings.

You should always test the hardware setup whenever you change it from the ScanMan Hardware Setup dialog box.

The Test button is dimmed if either the software and hardware I/O addresses do not match, or you have an I/O address conflict. You will need to resolve this problem before you can use your Logitech scanner. Refer to the ScanMan Installation Guide.


Reset

Click this button to reset hardware settings to either their initial settings, which displayed when you first opened the ScanMan Hardware Setup dialog box, or when you last clicked OK.

   Launching ScanMan Software

Because you can't launch ScanMan software directly from Windows Program Manager, you must first launch a TWAIN-compliant application.

Launch ScanMan software from within an application by choosing the Acquire command from the File menu.

If you have installed several TWAIN image sources, you must choose one source before you can acquire an image. The source remains selected until you select another one. If you have installed only one image source, you don't have to select it. Once you've selected ScanMan as the image source, you don't have to select the source every time you scan, only when you need to change sources.

To Select and Launch ScanMan:

1. From the application's File menu, choose Select Source. The Select Source dialog box appears, displaying the TWAIN image sources that you have installed.

2. In the Sources list box, click Logitech ScanMan.  If Logitech ScanMan is the only image source and is already selected, click cancel and skip step 3.

3. Click the Select button. Or, as a shortcut, simply double-click Logitech ScanMan in the Sources list box. This clears the dialog box.

4. Launch ScanMan software by choosing the Acquire command from the File menu. This displays the ScanMan Window


   Closing the ScanMan Window

After scanning, click Done, or press Enter to close the ScanMan window, and transfer the scanned image to an application. To close this window manually and return to the application without transferring a scan, do one of the following:

•  double-click the Control-menu box

•  click Cancel

•  press Alt-F4

•  press Esc

   Using the Scanner

Use the Scanning Guides (the small notches) at the front and sides of the scanner to position the scanner over an image. The notches at the front of the scanner indicate the scan width. The notches at the sides indicate the scan start point. If you have a ScanMan Color scanner, look through the window in the scanner to position the scanner over an image. Use the marks at opposite edges of the window to determine the scan width, and use the horizontal line across the width of the window to determine the scan starting point.

Place fingers and thumb on or near the top of the scanner and hold it in a relaxed fashion. It's much easier to scan in a straight line if you don't press down hard, and if you don't hold the scanner too tightly.

Roll the scanner over an image slowly and steadily in the direction of the cable. With ScanMan software, you can scan the image from top to bottom, left to right, or right to left.

As you roll the scanner, glance at the Scan Preview area of the ScanMan window to monitor the scan. Also be aware of the Speed indicators--one on the scanner, the other beneath the Scan Preview area. If either one shows yellow, slow your scan before it turns red, or you may lose image data and have to rescan.

ScanMan software will also sound a warning beep when you start scanning too fast (if you enable the Speed Warning option in the ScanMan Options dialog box).

Scan more slowly when you scan at a high resolution such as 300 or 400 dpi. The computer has to receive more image data from the scanner, especially if the image is gray or color.


   Scanning an Image

You should explore different settings, features, and options when you scan, to discover what works and what doesn't

To scan an image:

1. Choose the image you want to scan.

2. Launch the application. Double-click the application's icon from Windows.

3. (Optional) Select ScanMan software as the image source. Do this only if you have more than one image source, and the ScanMan software isn't already selected. Choose Select Source from the application's File menu. This displays the Select Source dialog box.

4. Launch ScanMan software from the application. Choose Acquire from the application's File menu.

5. Choose the scanner controls for the image. The Scanner Setup area displays the current Document Mode and Resolution. Depending on your scanner model and controller board, either change the settings on the scanner unit and/or from the Scanner Setup area.

6. (Optional) Choose a Scan Orientation and other scan options. Click a Scan Orientation icon to choose a direction for scanning. Also, choose other appropriate options in the ScanMan Options dialog box.

7. Position the scanner over the image. Use the Alignment Guides on the scanner unit or look through the scanner window.

8. Activate the scanner. Depending on your scanner model, press and release or press and hold the Scan Button. This activates the scanner's image-capturing ability.

9. Slowly and steadily roll the scanner over the image in the direction shown on the Scan Orientation icon. Always roll the scanner toward the cable. Some Logitech scanners have a self-tracking mechanism that keeps the scanner rolling in a straight line. Don't press down on the scanner or hold the scanner tightly (especially with your thumb). This produces a slanted scan.

10. Glance at the Scan Preview area and the Speed Indicator. Also glance at the Speed Indicator on the scanner. If you scan too fast, image data may be lost. The resulting image may be distorted, and you may have to rescan.

11. Deactivate the scanner. Depending on your scanner model, release or press and release the Scan button. This prevents the scanner from accidentally capturing additional, unwanted data.

12. End the scan session. Click Done. ScanMan software manipulates the image and transfers it to the application automatically.

   Canceling a Scan

Clicking any Scan Orientation icon cancels a single-scan strip or multiple-scan strips without clearing the ScanMan Window. You must rescan from the beginning. To rescan only the last strip in a multiple-strip scan, click Rescan or type R.


   AutoStitch

AutoStitch is a powerful ScanMan feature that enables you to scan more than a full page, merging up to four consecutive strips into a single image. Stitching automatically occurs after you click Done, just before the software transfers the image to the application. AutoStitch speed depends on how many strips you scanned, image size, document type, resolution, your computer type, and available RAM.

AutoStitch involves these phases: Finding Features, Matching Features, and Merging. The software tells you when these phases occur.

The Finding Features phase searches along the right edge of each strip to identify unique details, such as horizontal or vertical lines, or strong shade variations. The Matching Features phase matches the unique details found along the right edge of a strip with those found along the left edge of the next strip. The Merging phase straightens, stretches, and merges the strips together to make a single image.

AutoStitch is disabled under the following circumstances:

•  If you select Color document mode and 300 or 400 dpi resolution. At these settings, there is too much data for the software to AutoStitch.

•  If you select 100 dpi and gray document mode with a black-and-white scanner, such as ScanMan 32, ScanMan Plus, or ScanMan. The image isn't wide enough for the software to AutoStitch.

•  If you use an OCR application, such as OmniPage Direct AnyFont. OCR applications do their own stitching.

   Images with Poor Detail

Prepare an original image carefully before you scan. Image preparation saves hours of image editing time later. For example, use a pen or pencil to repair broken lines or use correction fluid to remove unwanted spots. If you can't work on the original, work with a photocopy or photostat of the image.


   Images Printed on Glossy Paper

Scanning glossy originals produces brighter, higher contrast images than original images printed on dull paper. To reduce distortion, put a glossy original in the ScanPad, reduce area light, or lower the scanner's contrast dial setting.


ScanPad

The Logitech ScanPad, available at computer stores, makes scanning easier. It's a folder with a clear, matte, plastic cover. The ScanPad insert contains a grid that helps you align images and scan in a straight line. The ScanPad cover holds images in place. Use the ScanPad for scanning small, single-strip glossy and textured images. For best results, keep the surface of the ScanPad clean.


   Images with Poor Contrast

When you scan high-contrast images with a scanner that has a contrast dial, adjust the dial to a lighter setting. If an image has low contrast, adjust the dial to a darker setting. Rescan the original until you're satisfied with the contrast, or edit it in an image-editing application such as FotoTouch Color.


   Images Printed on Textured Paper

To scan original images printed on textured or coarse paper, use the ScanPad or cover the original with a clear, matte, plastic sheet.


   Small Images

To scan pocket-size photographs, business cards and other small images that you have to hold in place as you scan, use the ScanPad, or tape the image to your desktop and cover it with a clear, matte, plastic sheet.


   Images that Contain the Color Red

Sometimes scanners have difficulty reading a color that is identical to the scanner light. If the scanner light is green, the color green in an image appears white, or is lighter than you would expect. The same distortion happens to the color red when the scanner light is red. To correct this problem, set the scanner's contrast dial to a darker setting, or scan a photocopy of the image. You can also use a felt-tip pen to change an area's color, or place a colored plastic sheet over the image -- yellow works well.

   Line Art (Black & White)

Clip art, text, architectural plans, sketches, and bar charts are line-art images. Line art images can have

•  black and white areas.

•  lines of one density. The line before you scan it can be any color.

•  colors of one density. All colors are represented as black, as long as they're all similar in density.

•  patterns or fills, such as lines or dot patterns used to separate adjacent areas.

The best line art images are sharp and have good contrast. To scan line art, set your scanner's Document Mode switch to Line Art, or choose Line Art document mode in the Scanner Setup area.


Continuous Tone
   Continuous Tone (Photographs)

A black-and-white or color photograph printed on photographic paper is a continuous-tone image.

Continuous-tone images are composed of gradient levels that have a full range of tones. Black-and-white photos shade from black to white. Color photos shade from darker to lighter hues. The best continuous-tone images have a broad, even distribution of tones. Avoid scanning images that limit tones to a narrow range of dark and light.

To scan continuous-tone images, set Document Mode to Gray or Color.


   Halftone

A black-and-white or color photograph printed in a book, magazine, or newspaper is a halftone image.

Halftoning is a printing process that allows devices, such as laser printers and Linotronic imagesetters, to reproduce the effect that continuous-tone images have on the eye. Halftoning approximates continuous tones with various sizes of small, solid dots. The eye merges these dots with the surrounding white area and perceives continuous tones. Look at a photo in a book, magazine, or newspaper with a magnifying glass, and you'll see the pattern of fine dots.

To scan a halftone image, set Document Mode to Gray or Color.

However, when you scan halftone images, the scanner applies its own dot pattern on top of the halftone dot pattern in the image. This can result in a noticeable grid affect or moiré pattern. To reduce moiré, try the following:

•   Scan at a slight angle.

•   Reduce the scanner's dpi setting, then save the image at an even lower resolution. You can also start by scanning at a higher resolution.

•   Use Smooth and Sharpen commands in an image editing application, such as FotoTouch.


Scanning Gray on a Black-and-White Scanner
   Scanning Gray Scale with a Black-and-White Scanner

If you have a black-and-white scanner, such as the ScanMan 32, ScanMan Plus, or ScanMan, you can scan in Gray document mode. To do so, set the scanner's Document Mode switch to the dither setting (the smallest dot) and select Gray in the Scanner Setup area. Also, set the scanner's Resolution Switch to 4 (400 dpi). Make sure that 400 dpi displays or is selected in the Scanner Setup area.

If you have a 200 dpi ScanMan scanner, you can't adjust the resolution.

ScanMan software automatically converts the black-and-white image data to gray scale. In the conversion process, ScanMan software divides the black-and-white image's resolution by 4. For example, if you scan an image at 400 dpi, the resulting gray-scale image is 100 dpi.


   Scanning in Gray Scale
or Color

When you scan in Gray or Color Document Mode with a ScanMan 256 or ScanMan Color scanner, set the scanner's resolution to 1 or 2 (100 or 200 dpi). Although scanning at 300 or 400 dpi reads more information per inch, you may not need it unless you plan to enlarge the image significantly.

A scanning resolution of 100 dpi is sufficient for most scans if you print your image on a laser printer with a resolution of less than 1200 dpi. Use 200 dpi if you print on a high-resolution Linotronic Imagesetter. An image scanned at 100 or 200 dpi usually produces the same results when printed, as when scanned at 300 or 400 dpi.

Using a lower scanning resolution has the advantage of making a smaller image file. Smaller image files can be a great advantage if you print magazine articles or high-quality newsletters that contain a number of large gray scale or color images.

   Scanning Straight

Some Logitech ScanMan scanners include a self-tracking mechanism that keeps them rolling in a straight line. Pressing down hard produces a slanted scan. If you have a scanner that requires you to press and hold the Scan Button, don't press hard with your thumb. You can guide your scanner by using a ruler or book as a straightedge or by using the grid on the ScanPad.


Single Strip Scanning
   Single-strip Scanning

Before you scan an image in one strip, check the Status area of the ScanMan window to make sure you aren't ready to scan strip 2, 3, or 4.

Then activate the scanner and scan the image. When you finish, click Done or press Enter to transfer the scanned image to the application.

Multi-Strip Scanning
   Scanning a Large Image
(Multiple-strip scanning)

Follow these guidelines when scanning in multi-strip scan mode.

Document Mode and Resolution. Don't use AutoStitch in Color document mode at 300 or 400 dpi to scan an image in multiple strips.

Enable AutoStop. When you enable the AutoStop option in the ScanMan Options dialog box, the software automatically gets ready to receive the next strip if you stop moving the scanner for more than two seconds. With AutoStop enabled, you don't have to click the Next Strip button after each strip.

Enable Use Calibration. Make sure that you enabled the Use Calibration option in the ScanMan Options dialog box if you scan in Gray or Color document mode. (The Use Calibration option is automatically enabled when you calibrate your scanner.) The Use Calibration option ensures that similar shades appear evenly across the width of a multiple-strip scan so that the stitching seam isn't visible.

   Resolution

The resolution at which you scan or save an image determines the number of dots per square inch required to make up that image. More dots per inch means greater image detail and a larger file size.

Scanner	Line Art	Gray	Color
Resolution	(B/W)

1 (100 dpi)	5K	40K	120K

2 (200 dpi)	20K	160K	480K

3 (300 dpi)	45K	360K	1,081K

4 (400 dpi)	80K	640K	1,922K

Approximate image size for a 4.1"x 1" scan saved in uncompressed TIFF format.

Notice that in any document mode, doubling the resolution quadruples the file size. Therefore, it's important to avoid scanning at resolutions higher than necessary.

Setting Resolution


   Document Mode

The document mode at which you scan determines the number of bits per pixel (bpp) required to make up the image.

More bits per pixel means higher gray or color values, and thus a better looking image. However, the more bits per pixel in an image, the larger the file size.

   Scaling Scanned Images

If you resize a scanned image, remember these guidelines.

Reducing Image Size

If you reduce the size of a Gray image after you scan it, set the scanner's resolution switch to 1 (100 dpi) and the Document Mode switch to Gray. If you have a ScanMan 256 scanner, set the Document Mode switch to 256. The 256 Gray document mode setting ensures that the image contains plenty of gray-scale data even after you reduce it, because some gray scale data is lost when you reduce the size of an image.

Avoid reducing a line art image. Unlike gray scale images, line art images are often distorted when reduced. If you must reduce a line art image, scan it at a resolution lower than your printer's resolution. For instance, scan an image at 100 or 200 dpi if you print it on a 300 dpi laser printer. Generally, you will achieve better results when reducing an image by a factor of 2 (50%).

Enlarging Image Size

If you enlarge an image after you scan it, set the scanner's resolution switch to 200, 300, or 400, dpi depending on the amount of enlargement. If you have a ScanMan 256 scanner and want to enlarge a gray image, set the scanner's document mode switch to 256.

   Printing Tips

Printer resolution depends on the type of printer you use. Printer resolution ranges from 60 dpi on some dot matrix printers, to 300 dpi on laser printers, to over 2,000 dpi on a Linotronic 300 imagesetter.

For the best image quality for a Line Art image on a laser printer, scan at the printer's resolution: 300 or 400 dpi.

For the best image quality for a Gray or Color image on a laser printer, scan at 100 dpi and print at as high a resolution as possible. Print on a laser printer equipped with an add-on enhancement board designed to improve resolution, or print on a Linotronic imagesetter at 1200 to 2400 dpi with an appropriate screen ruling. Linotronic imagesetters render more gray shades than laser printers.

  Why do I get image shifting or a gray background (or other image quality problems)?

  Why don't I see an image when I scan?

  Why won't the light turn off in the Scanning Window when I click the Stop or Done buttons?

  Why do images scroll so slowly in the Scan Preview area?

  When I scan in Gray document mode on my black-and-white scanner, why doesn't the final image resolution match the original scanning resolution?

  Why do I see shade variation between strips when I scan using AutoStitch?

  Why does a "Not Enough Features to Overlap" error message appear even though I have provided approximately 2 inches of overlap in my multiple-strip scan?

  Why do images appear in black and white in the Scan Preview area when I'm scanning in gray-scale or color document mode?

  Why is my image washed out even though the contrast dial is set at a darker setting?

  Why are vertical streaks in images I scan in gray scale or color document mode?

If you have any problems you can't solve, please contact Logitech Product Support.


Why do I get image shifting or vertical lines in Line Art mode or a gray background in gray document mode (or other image quality problems)?

Image distortion may be caused by a DMA or IRQ hardware conflict in scanners that use a bus card interface. Try selecting  different settings in the ScanMan Hardware Setup dialog box.

Image shifting can also be caused by scanning too fast. Check the Speed Indicator in the ScanMan Window as you scan.


Why don't I see an image when I scan?

Make sure that you activate the scanner properly. Depending on your scanner model, press and hold or press and release the Scan button.

Check the scanner's Contrast Dial. If the notch in the dial is positioned at the lightest setting, you may only see a white image in the Scan Preview area as you scan.

Check to see that you have enabled a Scan Preview mode in the ScanMan Options dialog box. If the Off option is selected, you don't see an image in the Scan Preview area as you scan.

If you have a scanner with a bus adapter, there may be an Interrupt Request or DMA conflict. Try selecting a different Interrupt Request or DMA channel number in the ScanMan Hardware Setup dialog box.

In the Hardware Setup dialog box, select a different Interrupt Request from the drop-down list box. Click Test to ensure that the scanner works properly. Follow the instructions in the ScanMan Test Procedure dialog box. If the test is successful, scan again. You should now see an image display in the Scan Preview area. If the test is unsuccessful, try another Interrupt Request, and retest the scanner. Follow the same procedure to change the DMA Channel Number.


Why won't the light turn off in the Scanning Window when I click the Stop or Done buttons?

It's normal for the light to stay on when you click Next Strip. The light remains on until you click Done. If the light remains on after you click the Done button, there may be a conflict with the current Board Base I/O Address setting, or there could be a conflict with a memory-resident application.

To determine whether there is a conflict with the current hardware Board Base I/O Address setting, change the current setting in the ScanMan Hardware Setup dialog box, and select a different Board Base I/O Address. If you have a scanner board with DIP switches, change the DIP switch settings to match. Click Test to ensure that the scanner works properly.

If the test is successful, scan again. The light should turn off. If the test is unsuccessful, try another Board Base I/O Address setting. If you have an older scanner board with jumper blocks, check your scanner manual for how to change the jumpers and for jumper settings.

To determine whether there is a conflict with a memory-resident application, unload each memory-resident application, reload each application one at a time, and scan until you determine which application is causing the conflict.


Why do images scroll so slowly in the Scan Preview area?

It could be that your computer's video display adapter can't scroll fast enough for the Scan Preview mode that you've enabled. To see the current Scan Preview mode, click Options in the ScanMan window to display the ScanMan Options dialog box.

The default Sweep Scan Preview mode should be selected. The Scroll option is slower than the Sweep option. Use Scroll only if you have a fast video display adapter. If the image still displays slowly, use the Off Scan Preview mode. You can't see the image as you scan, only after you click Done and the image is transferred to the host application.


When I scan in Gray document mode on my black-and-white scanner, why doesn't the final image resolution match the original scanning resolution?

ScanMan software automatically converts the image to gray scale. In the conversion process, ScanMan software divides the black-and-white image's resolution by 4. For example, if you scan an image at 400 dots per inch (dpi), the resulting gray-scale image is 100 dpi.

To scan in Gray document mode on a black-and-white scanner, set the scanner's Document Mode Switch to the smallest dither setting (the smallest dot) and set the resolution switch to 4 (400 dpi). Be sure that the settings in the Scanner Setup area match the settings you've set on your scanner.


Why do I see shade variation between strips when I scan using AutoStitch?

Maybe you haven't calibrated your scanner. Calibrating the scanner corrects the scanner's ability to read shades accurately, thus reducing shade variation between strips in a multiple-strip image.

If you still see shade variations, recalibrate your scanner with the contrast knob set to a lighter setting. (This doesn't apply to the EasyTouch scanner.)


Why does a "Not Enough Features to Overlap" error message appear even though I have provided approximately 2 inches of overlap in my multiple-strip scan?

You may have created too much overlap for the AutoStitch feature. The overlap area should be between 1/2 inch and 1 1/2 inches wide.

If you're scanning in Line Art mode, this message can appear if the strips don't have enough details for the software to find similarities. You can give the software a point of reference by writing an "X" near the top and bottom of the overlap area.


Why do images appear in black and white in the Scan Preview area when I'm scanning in gray-scale or color document mode?

This happens because of your computer's graphics adapter. For example, if you run Windows in standard VGA mode, an image appears in the Scan Preview area as black and white. However, when ScanMan software transfers the image to a host application, it appears in gray scale or color if the host application is able to display gray-scale or color image data.


Why is my image washed out even though the contrast dial is set at a darker setting?

A nearby bright light could be shining through your scanner's scanning window. Bright overhead light washes out image detail or causes a white line in the image. Turn off the overhead light or shade the scanner's window with your hand as you scan.

If your scanner uses a bus interface card, you should also check for DMA conflicts. You may need to change the DMA channel in the Hardware Setup dialog box.


Why are vertical streaks in images I scan in gray scale or color document mode?

Calibrate your scanner, if you haven't already.

If you have calibrated your scanner, recalibrate it, but first make sure that the plastic window under the scanner is dust-free. If it isn't, clean the window with a lint-free cloth. Be sure to use the calibration card that came with your scanner. The card should be clean.

Because strong surrounding light can cause streaking, don't calibrate your scanner or scan near or under bright lights. While scanning, you should also turn off overhead lights or cover the scanner window.
