Solutions

Diagnóstico rápido

This error typically appears as a message on the touchscreen followed by an automatic reboot. If the issue persists after the reboot, it is a software fault in the print queue or a corrupt driver on the PC sending the job. Determine if it happens with a specific document (e.g., a large PDF) or with any print job.

Solución paso a paso

  1. Disconnect the Ethernet cable or USB to isolate the printer from external data corruption.
  2. Turn off and on the device after 10 seconds.
  3. Clear the print queue on all computers connected to the network to remove pending corrupt jobs.
  4. Update the firmware by downloading the latest version from the HP support site and installing it via the control panel or USB.

Prevención y mantenimiento

Always keep the printer firmware up to date to patch known processing bugs. If using universal drivers, consider switching to the specific M653 series drivers to avoid command translation errors. Periodically clear print queues in busy office environments to prevent buffer overflow issues.

Cuándo llamar a un técnico

Contact professional support if the error appears even after disconnecting the network cable and performing a factory reset (NVRAM). This could indicate a fault in the internal memory (formatter board) on the motherboard.
