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 yo ur printed image only , your printer or it s

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 are as 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.
