If you hear a grinding noise before the E-05 appears, the toner cartridge is the most likely cause. Remove all cartridges and manually turn the internal gears to check for resistance.

Solución paso a paso

  1. Open the front cover and remove all toner cartridges.
  2. Inspect the internal cavity for spilled toner dust or paper scraps.
  3. Check if the cartridge gear rotates smoothly; if not, try a different cartridge.
  4. Restart the unit with cartridges correctly seated.

Prevención y mantenimiento

Use original Pantum CTL-1100 toner to ensure correct gear fit. Clean excess toner dust whenever you change consumables.
