When you see error 54.01, the printer has lost its connection to the toner sensor. Usually, toner leakage has clouded the sensor lens, making it impossible for the printer to 'see' the cartridge level.

Solución paso a paso

  1. Power off the device.
  2. Remove the toner and locate the sensor lens inside the print bay.
  3. Carefully wipe away any accumulated dust with a dry, clean cloth.
  4. Reinsert the cartridge firmly and power on the device.

Prevención y mantenimiento

Use a vacuum or compressed air to keep the interior of the machine clean. Avoid bumping or shaking the toner cartridge to minimize dust leakage.

Cuándo llamar a un técnico

If you have thoroughly cleaned the sensor lens and the 54.01 error remains, the hardware sensor may have failed and requires an official technician inspection.
