Make sure the document is flat against the document table.

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

Make sure the scanner 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]

Edges of the document are not scanned.

Position the document so the area you want to scan is within the edge guide limits of the document table.

[Top]

Colors are patchy or distorted at the edge of the image.

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.

[Top]

The image is faint or out of focus.

Make sure the document is flat against the document table.

Adjust your software's Exposure setting. See Image Controls.

Adjust your software's Gamma setting. See Making the Gamma setting.

[Top]

The image is too dark.

Check your software's Brightness setting.

Check the brightness and contrast settings of your computer display.

[Top]

Straight lines in the image appear 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]

The image does not look the same as the original.

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 image you want to scan.

[Top]

A line of dots is missing from the scanned image.

See your printer manual. Print head malfunction is indicated when a line is missing on printouts only.

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

[Top]

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

Change the Image Type settings. Turn the De-screening setting On in the Image Type dialog box.

Place a transparency sheet between the document and document table.

Reposition the document slightly.

Make the Image Size setting slightly smaller.

Change the focus position setting.

[Top]

Colors differ from the original.

Change the Image Type and Destination settings. See Selecting an Image Type and Selecting a Destination to make sure your settings are correct.

Printed colors will not exactly match the colors on your monitor, since printers and monitors use different color systems: monitors use RGB (red, green, and blue), while printers typically use CMYK (cyan, magenta, yellow, and black).

[Top]

Colors on your monitor are different from those in the original image.

Check the image settings of your scanner software, especially data format (bits, pixel, color), gamma correction, and color correction. Try different combinations of these settings.

Check the color matching and color management capabilities of your computer, display adapter, and software. Some computers can change the color palette to adjust the colors on your screen.

Exact color matching is very difficult. Check your software and monitor documentation for information on color matching and calibration. Also see your Color Guide.

[Top]

Printed colors are different from those in the original image.

Exact color matching is very difficult. Check your software or contact your printer company for information on color matching and calibration.

[Top]

The printed image is larger or smaller than the original.

The image size 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.

Make sure your printer is properly connected to the computer, correctly set up, and maintained. See your printer manual for details.

Check that your software is properly installed and set up for your printer.

[Top]

The colors of negative film preview images are not what you expect.

Make sure the EPSON TWAIN Pro Document Source setting is TPU for Neg. Film.

The dark area around the film, such as the frame of the film holder, is perceived as white, which alters the exposure of the scanning area and causes scans to appear darker. See the correct color by clicking and dragging the mouse over an area, and then clicking the Zoom Preview button.
