Visioneer Patriot 780 manual Problem The ADF won’t feed pages properly. How can I fix it?

142VISIONEER PATRIOT 780 SCANNER USER’S GUIDE

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.
