Check that the scanner is configured correctly. Check scan setting in the SmarThru

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

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.
