  • 1Paper jam not fully detected by the main sensor.
  • 2Premature wear of pickup rollers.
  • 3Motor overload due to debris accumulation on paper guides.
  • 4Electronic failure in the tray end sensor.

Solutions

Quick Diagnosis

If error E040 appears along with straining motor sounds, it means something is obstructing the paper path. Check all access doors and the fuser unit for scraps of paper, staples, or adhesive bits.

Step-by-step Solution

  1. Open all trays and side covers.
  2. Extract any paper remnants, even very small ones.
  3. Clean the feed rollers using an isopropyl alcohol wipe to improve traction.
  4. Reboot the printer after ensuring the path is completely clear of obstacles.

Prevention and Maintenance

Using improper paper weight is the number one cause of this error. Ensure tray guides are adjusted correctly. Periodic cleaning with compressed air helps remove paper dust that saturates transport sensors.

When to call a technician

If the error persists after confirming the path is free of jams, the main motor or paper synchronization sensor is faulty and requires replacement by an authorized technician.
