Common causes

  • 1Data corruption in high-resolution PDF or image files.
  • 2Printer temporary memory (buffer) overflow.
  • 3Conflict between installed driver and OS.
  • 4Internal hardware failure in the main memory module.

Solutions

Diagnóstico rápido

If the error appears right after sending a large file or one with complex images, the root cause is the saturation of temporary memory buffers due to that specific job.

Solución paso a paso

  1. Cancel all waiting print jobs from your computer control panel.
  2. Power off and disconnect the printer from the power source for 10 minutes.
  3. Reboot; if the error doesn't return, the issue was likely transient memory saturation.
  4. Try printing again, preferably with a simpler file version or after updating the driver.

Prevención y mantenimiento

Avoid sending multiple high-volume jobs simultaneously. Clean print logs regularly and update firmware if the manufacturer releases patches to improve memory management.

Cuándo llamar a un técnico

If the error 55 persists upon power-up even without any cables connected, the internal memory module on the logic board is likely damaged.
