Epson GT-5500 manual Line of dots is always missing in the scanned image

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 its print head is probably malfunctioning. (See your printer manual.)

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

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.

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.
