Problem: Why does my scanner not function after performing a system restore on Windows?
The system restore process may have corrupted some of the driver components. It is
recommended that you reinstall your scanner driver. Please refer to "Uninstalling Your Scanner" on
page 14 for installation instructions.
Problem: Why won't my scanner buttons work after scanning with Windows Image Acquisition
(WIA)?
After performing a scan using the WIA interface you must close the application you were using
before scanning with the buttons on the scanner. This does not occur when scanning using the
TWAIN or ISIS interface.
Problem: Why won't my scanner work after the computer has been sitting idle for several hours?
To resolve the problem, simply turn off the scanner power then turn it back on again.
This may occur after Windows goes into power saving mode to "hibernate" the computer into a
low power state. When you move your mouse or type on the keyboard it "wakes" the computer
back up and restores full power to the system. This power fluctuation during the computer's
hibernating period may sometimes cause the scanner to lose communication to the computer.
Problem: The installation will not complete successfully. If installation finishes, the scanner's
OneTouch options do not seem to work properly.
A likely cause is that some driver programs are already installed on your computer for another
® ®
scanner. Or you previously had another Visioneer or Xerox scanner and that driver program is
still on your computer. They are interfering with the installation and OneTouch options, and you
®
need to remove those other drivers and re-install your Xerox scanner. Please see the
documentation that you received with the other scanner for the steps to remove its driver
programs.
Problem: My computer keeps giving me out of hard drive space error messages.
The minimum requirement of free hard drive space is for the installation of the scanner driver and
basic, low resolution, scanning. High resolution scans result in files that can be over 1 gigabyte in
size. Free up some space on your hard drive for the software to be able to save the scanned
images.
Problem: The ADF won't feed pages properly.
A dirty or worn ADF pad assembly or dirt on the roller can cause documents to feed in skewed at
an angle, or multiple pages to feed at the same time. Try cleaning the roller first. See "Cleaning
Inside the Automatic Document Feeder" on page 4. If that doesn't solve the problem, the pad
assembly may need to be replaced. It is user replaceable. See "Replacing the ADF Pad Assembly"
on page 6 for the steps to replace the pad.
