TROUBLESHOOTING
Problem: The scanner won’t scan. What’s wrong?
Check for one of these possible problems:
• Is a cable loose or not plugged in securely? Inspect all cable connections. Make sure all the cables are
plugged in securely.
• Did you restart the computer after installing the software? If you didn’t restart the computer, it may not
have loaded all of the software files. Try restarting your computer.
• Did you select another TWAIN source for acquiring images? If you use multiple TWAIN devices with your
computer, you may have selected another source for images. Start the PaperPort software and make sure
TWAIN: Visioneer RoadWarrior 3 is selected as your scanner.
• Is the OneTouch icon in the Windows notification area? OneTouch must be installed for the scanner’s
AutoLaunch function to work. You can also try scanning from a TWAIN scanning application, such as
PaperPort.
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.
Problem: Why won’t my scanner work after the computer has been sitting idle for several hours?
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: I got the error message: PaperPort cannot allocate enough memory to perform internal critical
operations.
Close any other active applications so that additional memory is available. If you click Continue, PaperPort moves
the file to the PaperPort data directory and renames the file with the prefix “bad.” This allows you to recover the
file later. To recover the file, import it into PaperPort by using the Import command in the File menu.
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. They are
interfering with the installation and OneTouch options, and you need to remove those other drivers and re-install
your Visioneer RoadWarrior 3 scanner. Please see the documentation that you received with the other scanner for
the steps to remove its driver programs. After uninstalling the other scanner’s driver programs, uninstall
OneTouch using the steps on page 179 then install OneTouch following the instructions in the Installation
chapter.
Problem: My computer keeps giving me out of hard drive space error messages.
The minimum requirement of 350MB free hard drive space is for the installation of the software 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.
