• 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 44).
• 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.

setting in the application you want to use to make certain
that the scanner job is being sent to the correct port (for
example, USB001).

document after the received data has been printed.
