Suggested solutions
• 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 resolu-
tion 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 stan-
dards.
• 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.
• 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.
• There may be a copying or printing job in 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 communica-
tions.
• 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.
• The USB cable may be improperly connected or the power may be off.
• Do not use parallel and USB cables at the same time.
