may be incorrect.

The document may be
placed at an angle on
the document table.
Scan resolution may be
set too low.
A line of dots is always missing in the scanned image.
Problem
Your scanner may be
causing the problem.
Your printer may be
causing the problem.
Troubleshooting
Solution
Adjust the brightness setting in your software. Also check the
brightness and contrast settings of your monitor.
Solution
Align it so that the horizontal and vertical lines are carefully aligned with
the scales on the top and side of the document table.
Change the Resolution setting to a higher value. See your electronic
EPSON TWAIN Pro User's Guide or LaserSoft SilverFast Lite User's
Guide for information on setting the resolution. (Both guides are located
in the Manuals folder on your EPSON Expression 800 Scanning Tools
CD-ROM.) If you have the Artist or Professional model and are using
LaserSoft SilverFast 4.0, see the electronic guide on your LaserSoft
SilverFast CD-ROM.
Solution
If this happens on both your screen and printout, the scanner's sensor
may be malfunctioning. Consult your dealer.
If this happens in your printed image only, it may be caused by your
printer. See your printer manual for instructions on solving the problem.
