Troubleshooting Paper Misfeed Error 391

This code typically occurs due to dusty pickup rollers, paper stuck together by static, or loose tray guides.

Solution 1: Clean the Feed Rollers

With normal use, paper dust coats the rubber tires, causing them to slip instead of grabbing the top sheet.
  1. Pull Tray 1 completely out of the printer frame.
  2. Locate the rubber feed rollers on the underside ceiling of the tray cavity.
  3. Lightly dampen a clean, lint-free cloth with water (avoid rubbing alcohol as it dries out the rubber compound).
  4. Wipe the rollers thoroughly, rotating them manually to clear the whole surface.
  5. Let them dry, then replace the tray.

Solution 2: Prepare Paper Stack & Check Tray Guides

Humidity can make paper sheets stick together, leading to double-feeding or slipping.
  1. Take the paper stack out of the tray.
  2. Fan the sheets of paper to eliminate static cling.
  3. Reload the paper into the tray, making sure it doesn't exceed the limit mark.
  4. Align the plastic width and length guides tightly but without squeezing the edges.

Steps to follow

  1. 1

    Remove Tray 1

    Completely remove the paper cassette from the printer.

  2. 2

    Clean the pickup tires

    Wipe the rubber feed tires inside the tray ceiling with a damp cloth to remove paper powder.

  3. 3

    Fan paper and slide guides

    Fan the paper stack, reload it, and lock the plastic guides firmly in place.

Frequently asked questions

If the feed rollers are slipping and fail to pull the paper, the machine triggers a 'phantom jam' because the sensor expected a sheet to arrive but detected nothing.
