Scanning problems
Condition Suggested solutions
The scanner does
not work.
• Make sure that you place the original to be
scanned face down on the scanner glass, or
face up in the ADF.
• There may not be enough available memory
to hold the document you want to scan. Try
the Prescan function to see if that works. Try
lowering the scan resolution rate.
• Check that the USB or parallel cable is
connected properly.
• Make sure that the USB or parallel cable is
not defective. Switch the cable with a known
good cable. If necessary, replace the cable.
• If you are using a parallel cable, ensure that it
is compliant with IEEE 1284 standards.
• Check that the scanner is configured
correctly. Check scan setting in the
SmarThru
Configuration
or the application you want to
use to make certain that the scanner job is
being sent to the correct port.
The unit scans
very slowly.
• Check if the machine is printing received
data. If so, scan the document after the
received data has been printed.
• Graphics are scanned more slowly than text.
• Communication speed slows in scan mode
because of the large amount of memory
required to analyze and reproduce the
scanned image. Set your computer to the
ECP printer mode through BIOS setting. It
will help to increase the speed. For details
about how to set BIOS, refer to your
computer user’s guide.

progress. When that job is complete, try your
job again.
• The Selected port is currently being used.
Restart your computer and try again.
• The printer cable may be improperly
connected or the power may be off. You must
use a parallel cable that supports IEEE 1284
bi-directional communications.
• The scanner driver is not installed or the
operating environment is not set up properly.
• Ensure that the machine is properly
connected and the power is on, Then restart
your computer.

or the power may be off.

same time.
