Common causes

  • 1Sensor cover poorly positioned or broken.
  • 2Paper obstruction in the drum unit path.
  • 3Failure of the motor in the equipment laser unit.
  • 4Dust accumulation on laser mirrors.

Solutions

Diagnostic

The E1 error appears on the front panel of the HL-4150CDN when the printer cannot verify the state of the laser unit or drum cover. If you see that the motor starts but stops within a second, it is a clear symptom of the E1 error.

Step-by-Step Solution

  1. Full Opening: Open the top and front covers of the equipment.
  2. Drum Inspection: Extract the drum unit (DR-310CL) and ensure there are no paper obstructions.
  3. Sensor Closing: Verify that the door safety tabs are not broken.
  4. Restart: Turn off the machine for 30 seconds and turn it back on with everything in place.

Prevention and Maintenance

Clean the drum corona wire monthly using the green tab. Keep the equipment on a level surface to prevent internal sensor misalignment.

When to Call a Technician

If the E1 error persists after following the steps above, the laser polygon motor might be jammed or damaged, requiring specialized technical intervention.
