Suggested solutions

 

 

 

 

The scanner does not work.

• Make sure that you place the document to be scanned

 

 

face down in the ADF.

 

 

• 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.
