Solutions

Quick Diagnosis

If you hear a buzzing noise followed by error E-4, the motor is fighting a physical obstruction. Why does my HP LaserJet 1020 show error E-4? Usually, a piece of paper is stuck in the rollers.

Step-by-Step Solution

  1. Inspect: Remove the toner and check for debris along the path.
  2. Manual Test: Try to turn the rollers gently; if there is resistance, you must clear the obstacle.
  3. Reset: Disconnect the power and let the printer rest for 10 minutes.

Prevention and Maintenance

Use 75-80g/m2 paper to avoid mechanical motor blocks.

When to call a technician

If the motor makes a metallic grinding noise or error E-4 appears even without the toner, the drive motor has likely failed.
