Visioneer OneTouch 7400 manual Troubleshooting

TROUBLESHOOTING 109

Problem: The installation will not complete successfully. If installation finishes, the scanner’s OneTouch 4.0 options do not seem to work properly. What do I do?

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 7400 USB scanner. Please see the documentation that you received with the other scanner for the steps to remove its driver programs. You can also use the basic steps in the section “Uninstall Your Scanner” on page 110, but in Step 3, instead of uninstalling OneTouch 4.0, uninstall the other scanner’s driver programs. After uninstalling the other scanner’s driver programs, uninstall OneTouch 4.0 using the steps on page 110, then reinstall it using the steps on page 6.

Problem: My computer keeps giving me out of memory error messages. What do I do?

Make sure that your system meets the minimum requirements for using the scanner.

■A minimum of 256 MB (megabytes) of internal memory (RAM) for Windows 2000 and Windows XP

■512 MB is the minimum requirement as set by Microsoft for Windows Vista

Problem: My computer keeps giving me out of hard drive space error messages. What do I do?

The minimum requirement of 200MB free hard drive space is for the installation of the software and basic scanning functions. High resolution scans result in files that can be over 1 gigabyte in size. Free up space on your hard drive for the software to be able to save the scanned images.
