A line of dots is always missing in the scanned image . . .

■If this happens in your printed image only, your printer is low on ink or toner. Replace your ink or toner cartridge. If this does not solve the problem, your printer may be malfunctioning. (See your printer manual.)

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

■If this happens on both your screen and printout, the document table glass may be dusty or scratched. Clean the document table glass.

■If you are using the auto document feeder, the paper path guide of the auto document feeder may be dusty. Clean the paper path guide. If the problem still exists, the guide may be scratched and must be replaced.

Textured patterns of dots appear on areas of an image . . .

You are using halftoning, which causes normal moiré patterns. Your scanner automatically minimizes the problem if you turn on De-screening in the Image Type dialog box.

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

■Because your monitor and printer use different technologies to represent colors, your printed colors cannot exactly match the colors you see on your monitor screen.

■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.

■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, monitor, and computer manuals for information on color matching and calibration.)
