Fix Printer ERROR 11 Paper Out

Error code 11 Problem: " Paper out" error message

Possible Causes and Solutions:

1. Paper tray empty or not seated correctly. First try to re-seat the paper tray by pulling it out, making sure there are no obstructions in it's path and reinsert it. A buildup of toner on the edges of the tray which slide into the printer can sometimes cause problems. Take a sharp tool, like a razor blade and scrape the buildup off these edges. Also, check for cracks in the cassette. The cassette will loose it's stiffness and keep from holding its shape when there are cracks or small guide tabs that break off.

2. Sensor Arm Stuck or Broken - check for free movement of the sensor arm. On the LJ4/4M/4+/4M+ the sensor flag can get knocked out of place when a paper jam occurs and the tray is pulled out abruptly. Most times this can simply be reinstalled. If it's broken, you will need to replace the sensor flag.

3. Defective Tray Size Sensing or Configuration - Most trays have tabs which depress a series of switches when installed. Verify that the tabs aren't damaged and that the tray switches located in the printer are not damaged. You can depress these by hand and hear them click. Occasionally the contact for the micro switch will get bent and will have to be replaced. Also verify the configuration through the menus on the printer.

4. Defective Paper Control Sensor PCB - These do fail and will need to be replaced.
