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 Inside the
Automatic Document Feeder on page 32 for cleaning instructions.
Problem : The ADF won’t feed pages properly.
A dirty or worn roller can cause documents to feed in skewed at an angle, or multiple pages to feed at the same
time. First, try cleaning the rollers as described in
Cleaning Inside the Automatic Document Feeder on page 32. If
the problem persists, the separation and/or feed rollers may need to be replaced. Please see Replacing the
Separation Roller on page 34 and Replacing the Feed Roller on page 36.
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 : 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.
