Problem: The paper jams the ADF.
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 152 for cleaning instructions.
Problem: The ADF won’t feed pages properly.
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 152. If that doesn’t solve the problem, the pad assembly may need to be replaced. It is user-
replaceable. See
Replace the ADF Pad Assembly on page 154 for the steps to replace the pad.
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.
Problem: Paper jams when it begins scanning from the input tray.
Make sure the front feed tray is closed, and that an item isn’t already in the scanner fed in from the
front.
Problem: The scans from the input tray are always crooked.
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 from the front feed tray instead.
Problem: The scanner reports a Double Feed error when there is only one page in the scanner.
Try cleaning the double feed detection sensor. Dust on the sensor may prevent the sensor from working
properly.
