page 115, but in Step 3, instead of uninstalling One Touch 4.0,
uninstall the other scanner's driver programs. After uninstalling the
other scanner's driver programs, uninstall One Touch 4.0 using the
steps on page 115, then reinstall it using the steps on page 7.
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 Scanner" on
page 103 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
Scanner" on page 103. If that doesn't solve the problem, the pad
assembly may need to be replaced. It is user-replaceable. See
"Xerox DocuMate 632 Scanner Parts List" on page 118 for the
ordering number. See "Replacing the ADF Pad Assembly" on
page 106 for the steps to replace the pad.
Problem: The paper jams about halfway through the
scan. How can I keep this from happening?
Check the flatbed glass to make sure no items are on it when you
scan from the ADF. Multiple items placed on the flatbed glass will
raise the lid slightly, thus preventing the pages feeding through the
ADF from touching the glass. When that occurs, the pages are
unable to feed back out of the ADF and the pages can jam.
Problem: The motor runs but doesn't feed the paper.
How can I fix it?
Make sure the paper is securely seated in the ADF so the paper
rests on the rollers. The paper sensor that initiates the rollers to
grab the paper may be engaged, but the paper may not be fully in
the ADF tray so the rollers cannot grab a page to feed it through.
