Note:
When the Stylus Scan is connected through the parallel interface on a Windows system, it will be impossible to use the scanner if the printer driver is uninstalled.

Operating problems

Problems you may have while using the scanner often involve the operation of your software and computer. Operation problems usually occur because of:

Also see the documentation that came with your computer and printer for possible solutions.

The operate light does not come on

Press the power button to turn on the Stylus Scan.

Make sure the power cord is correctly plugged into the Stylus Scan and the power outlet.

The scanner does not start scanning

Make sure that the Operate light is green (indicating that the Stylus Scan is ready).

The scanner software does not work properly

Be sure you have correctly installed your software.

Make sure that your computer system meets the requirements specified by your software.

Confirm that the computer has enough memory for your software. If your computer has many device drivers, if you are running other software at the same time, or using RAM-resident programs, the computer may not have enough memory available. (See your software and computer documentation.)

Quality problems

The entire image is distorted or blurred

Make sure that the document is placed flat against the document table.

You may have accidentally moved the document during scanning. Check the position of the document and do not move it while the Stylus Scan is operating.

See that the Stylus Scan is not tilted or placed on an unstable surface.

Part of the image is distorted or blurred

Part of the document may be wrinkled, warped, or not in contact with the document table. Be sure the document is flat.

Caution:
Do not place heavy objects on the document table.

Edges of the document are not scanned

The document table has non-readable areas around the edges. If part of your document extends beyond the maximum limits marked on the document table edge guides, you may have to reposition your document so that the image you want to scan is within the readable area.

Color is patchy or distorted at the edges of the image

If the document is very thick or warped at the edges, the edges of the image may be discolored. Cover the edges of the document with opaque paper to block outside light.

If part of the document extends beyond the document table, that edge may not be in contact with the document table. Change the position of the document.

The image is faint or out of focus

Check that the document is placed flush against the document table.

Check the Gamma setting in your software.

Check the Exposure setting in your software.

The image is too dark

Adjust the brightness and exposure with your software. Also check the brightness and contrast values of your display screen.

Straight lines in the image are jagged

The document may be placed at an angle on the document table. Align it so that the horizontal and vertical lines are carefully aligned with the scales on the top and side of the document table.

The image does not look the same as the original

Try different combinations of image settings using your scanner software.

Your software may not have sufficient color matching and color management features, or these components of your software may not be correctly installed. (See your software and computer manuals.)

If you are importing an image file into your application software, make sure the file format is one your software can read. Also check that the image settings in your application are appropriate for the type of image you want to scan. (See your software manual.)

A line of dots is always missing in the scanned image

If this happens in your printed image only, your printer or the print head is probably malfunctioning. Consult your dealer.

If this happens on both your screen and printout, the scanner's sensor may be malfunctioning. Consult your dealer.

A line of dots always appears in the scanned image

If this happens on both your screen and printout, the paper path guide of the Auto Document Feeder or 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.

When halftoning is used, textured patterns of dots appear on particular areas of an image

This is normal. See the explanation of moiré patterns in the Color Guide. Your scanner automatically minimizes the problem if Best & de-screening is selected for the Quality & De-screening setting in the Image Type dialog box.

Colors in the image look odd

Make sure the Image Type and Destination settings in EPSON TWAIN are selected correctly.

When you are using the Film Adapter, make sure the rectangular opening near the hinges on the base is uncovered, or make sure the top of the Film Adapter is closed when scanning.

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

Check the image settings in your scanner software, especially data format (bits/pixel/color), gamma correction, and color correction. Try a different combination 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. (See your software and computer manuals.)

Exact matching of colors is very difficult. The reason for this is explained in your Color Guide. Check your software and monitor manuals for information on color matching and calibration.

Printed colors are different from those in the original image

Exact reproduction of colors is very difficult. The reason for this is explained in your Color Guide. See your software manual or your printing company for guidance on color matching.

The printed image is larger or smaller than the original size

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

Your image cannot be printed or the printout is garbled

Check that the printer is properly connected to the computer and is correctly set up.

Check that your software is properly installed and set up for your printer. (See your software manual.)

Color of negative film preview images looks odd

Check that TPU for Neg. Film is selected in the Document Source settings in EPSON TWAIN.

The dark area around the film, such as the frame of the film holder, is perceived as white - altering the exposure of the scanning area and causing your scans to appear darker. See the correct color by clicking and dragging the mouse over an area, then clicking the zoom preview button.

Improving scan speed

If the Stylus Scan is connected by a parallel interface (Windows systems only), the best way to improve the speed of your scans is to make sure ECP mode is enabled on your system. This is a system-level setting, so if you want to change it, contact the manufacturer of your computer.

Always use the lowest Resolution (dpi setting) possible that will still give good image quality. A higher dpi setting may not increase the quality of a scan, but it will significantly slow down your computer and it will require more disk space to save the image.
