Solutions

The P01 error is straightforward: the display notifies that the toner is missing or unrecognized. If you recently replaced your toner, it is almost certainly a contact issue between the chip and the printer's internal pins.

Solución paso a paso

  1. Open cover: Open the front cover to access the toner bay.
  2. Remove cartridge: Gently pull out the toner cartridge.
  3. Clean contacts: Use a dry cloth to wipe the metal chip contacts on the toner.
  4. Reinstall: Insert the cartridge firmly until it clicks into place.

Prevención y mantenimiento

Always handle toner cartridges by the plastic casing rather than the chip surface. Regularly vacuum the area inside the bay to prevent toner dust from insulating the contacts.

Cuándo llamar a un técnico
