Edges of the document are not scanned

Try one or more of these solutions:

• Make sure the document is aligned with the alignment mark. See Placing Photos and Documents on the Document Table.

• Position the document so the area you want to scan is within the edge guide limits of the document table. The area with a width of maximum 2.5 mm from both the horizontal and vertical guides is not scanned.

Try one or more of these solutions:

• Make sure the document is placed on the document table of this product.

• Change the Threshold setting in the Image Control dialog box. Select Text/Line Art as the Image Type, and then change the Threshold setting in the Image Control dialog box.

The image does not look the same as the original

Try one or more of these solutions:

• Try different image setting combinations on your scanner software.

• Your software may not have sufficient color matching and color management features, or these components may not be installed correctly. See the documentation that comes with your software and computer.

• If you are importing an image file, make sure the file format is one your software can read. Also, make sure the image settings of your software are appropriate for the type of scanned image.

A line of dots is always missing from the scanned image

Scanner sensor malfunction is indicated when a line is missing on both screen images and printouts. Contact your dealer.

[Top]

A line of dots always appears in the scanned image

If this happens on both your screen and printout, the document table may be dusty or scratched. Clean the paper path guide or clean the document table. If the problem still exists the guide may be scratched and require replacement.

[Top]

Straight lines in the image come out jagged

Make sure the document orientation is perfectly straight on the document table. Align vertical and horizontal lines with the scales at the top and side of the document table.

[Top]

Scanned image by using the buttons on the control panel is missing

Make sure desired application is assigned to the buttons on the control panel.

[Top]

The entire image is distorted or blurred

Try one or more of these solutions:

• Make sure the document is flat against the document table.

Caution:

Do not place heavy objects on the document table.

• Make sure you do not accidentally move the document during scanning.

• Make sure this product is on a flat, stable surface.

[Top]

Part of the image is distorted or blurred

Make sure the document is uniformly flat against the document table. A document that is wrinkled or warped may not scan well.

Caution:

Do not place heavy objects on the document table.

[Top]

Colors are patchy or distorted at the edges of the image

Try one or more of these solutions:

• A document that is very thick or warped at the edges can cause discoloration. Cover the edges of the document with paper to block outside light.

• Make sure the document is flat against the document table.

Caution:

Do not place heavy objects on the document table.

[Top]

The image is faint or out of focus

Try one or more of these solutions:

• Make sure the document is flat against the document table.

Caution:

Do not place heavy objects on the document table.

• Adjust your software's Exposure setting using the Auto Exposure button in the Professional Mode.

• Adjust your software's Gamma setting using the Histogram Adjustment dialog box in the Professional Mode.

[Top]

The image is too dark

Try one or more of these solutions:

• Check your software's Brightness setting using the Image Adjustment tools in the Home Mode or the Histogram Adjustment dialog box and the Image Adjustment dialog box in the Professional Mode.

• Check the brightness and contrast settings of your computer display.

[Top]

Image is dark, with little or no detail

Try one or more of these solutions:

• Change the Display Gamma setting. See online help for details.

• Change the Destination setting in the Home Mode or the Professional Mode main window.

• In the Home Mode, select Screen/Web as the Destination. Selecting a printer may cause on-screen colors to be different from the colors of the original, however, colors will be reproduced correctly when the image is printed.

[Top]

Scanned image is too large

Change the Target Size setting of the Destination setting in the Home Mode or the Professional Mode main window.

[Top]

Moiré (cross-hatch) patterns appear in the scanned image

A moiré is a cross-hatch pattern that appears on the scanned images when scanning printed materials. It is a result of interference that occurs due to the difference between the pitches of the scanning and the halftone screens.

Try one or more of these solutions:

• Check the Descreening Filter check box in the Home Mode or the Professional Mode main window.

• In the Professional Mode, set the Screen Ruling of the Descreening Filter setting to the appropriate setting for your document.

• Place a transparent sheet such as an overhead projector sheet, between the document and the document table.

• Reposition the document slightly.

• Make the image size slightly smaller.

Poor character recognition during OCR scanning

Try adjusting the Threshold setting. See Scanning Documents to Convert to Text Data (OCR) for more information.

[Top]

The printed image is larger or smaller than the original

The image size and resolution settings of your software determine the size of the printed image. Do not use the size of the monitor image to judge the printed size.

[Top]

Scanned images cannot be printed or come out garbled when printed

Try one or more of these solutions:

• Make sure this product is properly connected to the computer, correctly set up, and maintained.

• Check that your software is properly installed and set up for this product (see your Setup Sheet).

Images cannot be located properly in the Thumbnail preview

Try one or more of these solutions:

• In the Preview window, create marquees on the area you want to scan, and then scan.

• In the Configuration dialog, adjust the thumbnail cropping area using the Thumbnail Cropping Area slider.
