Scanning problems Fax problems (optional)
Conditon 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 DADF.
• 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 machine cable is connected
properly.
• Make sure that the machine cable is not
defective. Switch the cable with a known
good cable. If necessary, replace the cable.
• Check that the scanner is configured
correctly. Check scan setting in the Easy
Document Creator or the application you
want to use to make certain that the scanner
job is being sent to the correct port (for
example, USB001).
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.
