Solutions

Diagnóstico rápido

If the Fujitsu DPK905 error E-2 appears, look for resistance when manually moving the printhead carriage. The error is a feedback notification from the motherboard stating the carriage is not responding as expected.

Solución paso a paso

  1. Turn off the printer and disconnect from the power supply.
  2. Gently slide the carriage left and right to identify if there are any obstructions.
  3. Clean the carriage rail thoroughly with a lint-free dry cloth.
  4. Apply a small amount of dry lubricant if the metal rod feels dry.
  5. Restart the printer to allow for a new home calibration cycle.

Prevención y mantenimiento

Clean the carriage guide rails every month, especially if the printer is located in a dusty environment. Using genuine Fujitsu ribbon cassettes ensures proper tension against the head, preventing extra wear and tear.

Cuándo llamar a un técnico

If the carriage still stops after cleaning and lubrication, the carriage motor, the timing belt, or the main sensor may require expert replacement.
