Solutions

Diagnóstico rápido

When the error 5002 flashes on your screen, it identifies a communication break in the printhead hardware. This is not a software error, but a physical connectivity issue between the printer motherboard and the printhead assembly that requires direct inspection.

Solución paso a paso

  1. Completely power down the unit and unplug the AC cable.
  2. Access the internal printhead cavity.
  3. Carefully reseat the flat cable and ensure the locking tabs are secure.
  4. If visual inspection is clear, try restarting the printer to see if it clears.

Prevención y mantenimiento

Use original supplies to maintain the correct operating temperature and friction levels for the printhead. Clean the assembly periodically to ensure perfect electrical connectivity and clear print results.

Cuándo llamar a un técnico

If the cable reseating does not resolve the error 5002, the printhead assembly likely has a failed internal sensor or circuit and will need to be replaced by authorized staff.
