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.
Problem: The scans from the ADF are always crooked. What do I
need to do to get the scans straight?
Make sure to align the paper guides to the edges of the paper. If you are
scanning small items that are smaller than the paper guides’ minimum
adjustment, scan these items on the flatbed glass instead.
Problem: If the USB cable is disconnected during a scan, the
scanner does not reconnect when the USB cable is plugged back in.
Unplug the power cable from the scanner, and then plug it back in.
If the scanner does not reconnect:
1. Unplug the power cable from the scanner.
2. Restart your computer.
3. After the restart is complete, plug the power cable back in.
