Scanning Problems

Condition

Suggested solutions

 

 

The scanner does not work.

• Make sure that you place the document to be

 

scanned face down on the document glass, or

 

face up in the Automatic Document Feeder.

 

• 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, for example, LPT1.

 

 

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.
