The scanner does not work.

• Make sure that 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 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 the IEEE 1284 standard.

• 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, for 

example, LPT1.

The unit scans very slowly.

• Check if the machine is printing received data. Scan 

the document after the current job is completed.

• 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 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  is  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 the current job is complete, try the 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 USB 1.1 compliant 

cable or a parallel cable that supports IEEE-1284 bi-

directional communications.

• The scanner driver is not installed or an operating 

environment is not set up properly.

• Ensure that port is properly connected and power is 

on, and then restart your computer.

• Do not use the parallel and the USB cables at the 

same time.
