Scanning Problems
Symptom Cause and Solution
The scanner does not
scan.
Make sure you place the document to be
scanned face down on the document
glass.
There may not be enough available
memory to hold the document you want
to scan. Try the Pre-Scan function to see
if that works. Try lowering the scan
resolution rate.
The USB or parallel cable is not
connected properly.
The USB or parallel cable is defective.
Swap the cable with one known to work.
If necessary, replace the cable.
If using a parallel cable, ensure that it is
compliant with the IEEE 1284 standard.
The scanner is configured incorrectly.
Check scanner setting in scanner driver
to make certain that the scanner job is
being sent to the correct port (for
example, LPT1).
The unit scans very
slowly.
Graphics are scanned more slowly than
text.
Communication speed becomes slow in
scan mode because of the large amount
of memory required to analyze and
reproduce the scanned image. Set your
computer to ECP printer mode through
BIOS setting. It will help to increase the
speed. For details on how to set BIOS,
refer to your PC documentation.
