  1. Power off: Disconnect from the power source.
  2. Wait: Let the internal memory clear.
  3. Restart: Turn on in isolation.
  4. Firmware update: Check HP support for the latest updates.

Prevention and Maintenance

Regularly update your printer's firmware through the EWS. Keep the network environment clean by purging old print queues periodically.

When to call a technician

If the error persists after multiple firmware reloads and cable checks, there is likely a permanent failure on the main system board.
