Basic troubleshooting tips
Simple issues such as smudges on the scanner glass or loose cables can cause your
scanner to produce fuzzy scans, operate in an unexpected manner, or fail to operate.
Always check the following items when you encounter scanning problems.
•
If scans are fuzzy, check to see if the scanner glass or TMA is dirty or smudged. If
so, clean the glass or TMA.
• If you are scanning a document using an OCR shortcut, make sure that the original
document is clear and crisp enough to be scanned.
• Make sure that the TMA/ADF, USB or Ethernet, and power cables are firmly seated
in their respective connectors on the back of the scanner, and that the power cord is
plugged into a working electrical outlet.
• If you have connected the scanner to the computer through a USB hub or through a
USB port on the front of the computer, disconnect the scanner and then reconnect it
to a USB port on the back of the computer.
• Make sure the scanner is not connected to both a computer with the USB cable and
to a network with the Ethernet cable. If the scanner is connected with both cables,
the USB connection disables the Ethernet (network) connection.
• If you have connected the scanner to a network, disconnect the Ethernet cable from
the network and connect it to a different network connection (for example, to a
different port on a network router). If this does not work, reboot the router.
• Turn off the scanner, wait 60 seconds, and then turn on the scanner.
• Restart the computer.
If you continue to have problems, it is possible that your HP scanning software, firmware,
or associated drivers are out of date or have become corrupted. See
