Scanning Problems
Problem
Action
The scanner does not work.
Make sure that you place the document to be scanned facing down on the
document glass.
There may not be enough available memory to hold the document you want to
scan. Try the Preview function to see if that works. Try lowering the scan
resolution rate.
If you are using wireless connection, make sure that the wireless connection is
established.
If you are using USB connection, make sure that you are using the correct USB
cable and that it is securely connected to the printer.
Make sure that the USB cable is not defective. Switch the cable with a known
good cable. If necessary, replace the cable.
Check that the scanner is configured correctly. Check the application you want to
use to make certain that the scanner job is being sent to the correct port.
The printer scans very slowly.
Graphics are scanned more slowly than text when using the Scan to E-Mail or
Scan to Network feature.
Communication speed becomes slow in scan mode because of the large amount
of memory required to analyze and reproduce the scanned image.
Scanning images at a high resolution takes more time than scanning at a low
resolution.
A smear appears at the same
location on the output when scanned
using the document glass.
Clean the document glass.
