4.2.2.5 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 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 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.

Message appears on your

computer screen:

• “Device can’t be set to the

H/W mode you want.”

• “Port is being used by

another program.”

• “Port i s Disabled.”

• “Scanner is busy receiving

or printing data. When the

current job is completed,

try again.”

• “Invalid handle.”

• “Scanning has failed.”

• 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

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.

• The USB cable may be improperly connected or the power may be off.
