Solutions

Diagnóstico rápido

The 1403 error appears immediately on the control panel when sending a job or powering on. It's distinct because it fully locks the print carriage. Unlike paper jam errors, this is specific to the electronic communication between the logic board and the printhead.

Solución paso a paso

  1. With the printer on, open the front ink access cover.
  2. Wait for the carriage to move to the center, then unplug the power cord.
  3. Lift the locking lever and carefully remove the affected printhead.
  4. Gently clean the gold contacts on the printhead with a dry, lint-free cloth.
  5. Reinstall the printhead, ensuring it clicks into place, then lower the lever.
  6. Plug in and power on the printer to trigger a system verification.

Prevención y mantenimiento

Never touch the electrical contacts of the printhead with your fingers, as natural skin oils can cause short circuits. Use only original inks to prevent sediment buildup that may clog nozzles and stress the printhead.

Cuándo llamar a un técnico

If the 1403 error persists after cleaning the contacts and reseating the head, the printhead has likely suffered an irreversible electronic failure and must be replaced.
