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 Patriot 780 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 “Uninstalling Your Scanner” on page 145, 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 145, then reinstall it
using the steps on page 9.
Problem: The paper jams the ADF. How can I keep the paper from
jamming so often?
To reduce the number of paper jams, smooth and straighten the paper
before scanning, and adjust the guides to the paper size. Paper fed into
the ADF at an angle can cause the feed mechanism to jam. If paper jams
are occurring more frequently, try cleaning the roller with a soft cloth
dampened with Isopropyl rubbing alcohol. Excessive dust on the roller
can make it appear worn and will cause issues feeding paper. See
“Cleaning the Automatic Document Feeder” on page 139 for cleaning
instructions.
Problem: The ADF won’t feed pages properly. How can I fix it?
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 the Automatic
Document Feeder” on page 139. If that doesn’t solve the problem, the
pad assembly may need to be replaced. It is user-replaceable. See
“Visioneer Patriot 780 Scanner Parts List” on page 148 for the ordering
number. See “Replacing the ADF Pad Assembly” on page 140 for the
steps to replace the pad.
