Faxing Problems
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.
