Scanning problems
Condition Suggested solutions
The scanner does not work. • Make sure that you place the original to be scanned face down on the scanner glass, or face up in the document feeder (see
"Loading originals" on page 46).
• 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 machine printer cable is connected properly.
• Make sure that the machine printer cable is not defective. Switch the printer cable with a known good cable. If necessary, replace
the printer cable.
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.
