Basic troubleshooting tips
Simple issues such as smudges on the scanner glass or a loose cable 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 is dirty or smudged. If so, clean
the glass.
•
If you are scanning a document using an optical character recognition (OCR)
shortcut, make sure that the original document is clear and crisp enough to be
scanned.
•
Make sure that the USB cable is securely connected between the scanner and the
computer.
•
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.
•
Restart the computer.
•
If a program has frozen, close it.
◦
Windows: Press and hold CTRL, ALT, and DELETE to open the Windows Task
Manager dialog. In the Applications tab, select the application to shut down,
and then click End Task.
◦
Mac: Press and hold Option, Command, and Esc. In the Force Quit dialog,
select the program to shut down, and then click Force Quit.
