The error 04-305 is almost always resolved in seconds. If you wonder why does my Pantum TL-410 show error 04-305?, check for cables or paper debris blocking the front or rear door path.

Solución paso a paso

  1. Full open: Open all covers (front and back).
  2. Inspect: Verify there are no broken plastics or paper bits in the latches.
  3. Firm close: Press each cover firmly on the edges until you hear the sensor click.

Frequently asked questions

No, it's a protective measure to prevent the laser from operating while the printer is open. It is easily resolved.

Sometimes an improperly seated toner prevents the cover from closing correctly, triggering this safety error.
