Copy/Scan Problems WC 3335 and 3345
If the scanner does not work or operates slowly, check the following:
1.
Ensure that you place the document to be scanned face down on the document feeder glass, or
face up in the ADF/DADF.
2. There may not be enough available memory to hold the document you want to scan. Try lowering
the scan resolution rate, or if its a multiple page document, try scanning fewer pages.
3. Check that the USB cable is not defective and is connected properly. If necessary install a new USB
cable.
4. 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.
5. Graphics are scanned more slowly than text when using the Scan to E-mail or Scan to Network
feature.
6. Communication speed becomes slow in scan mode because of the large amount of memory
required to analyze and reproduce the scanned image.
7. Scanning images at a high resolution takes more time than scanning at a low resolution.
8. If scanned image quality is bad, but internal prints are good, replace the Scanner.
