Ensure that you place the document to be scanned facing down from the document feeder glass, or facing up in the ADF. 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 USB or Ethernet cable is connected properly. Ensure that the USB or Ethernet cable is not defective. Switch the cable with a known good cable. If necessary, replace the cable. If using the network TWAIN (WIA) driver, check that the Ethernet cable is connected properly and the IP address of the printer is set correctly. To check the IP address, see "Verifying the IP Settings." 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. Ensure that the scanner sharing feature is disabled when you use Mac OS X before you scan documents via an ICA compatible application such as Image Capture. The printer does not support the scanner sharing feature of Mac OS X. Select a printer which is directly connected to the computer via USB or wired /wireless LAN and scan documents. 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.
