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, clean the rollers. 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 USB cable is firmly seated in the USB port on the back of the scanner.

•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.

•Disconnect the USB cable, wait 60 seconds, and then reconnect the USB cable.

•Restart the computer.

If you continue to have problems, it is possible that your HP scanner firmware, or associated driver are out of date or have become corrupted. See www.hp.com/support to locate firmware, and driver updates for your scanner.
