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, 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 that the scanner buttons are enabled.
•
Turn off the scanner, wait 60 seconds, and then turn on the scanner.
•
Test the scanner hardware.
•
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or associated drivers are out of date or have become corrupted.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
www.hp.com/
support
to locate software, firmware, and driver updates for your scanner.
