Common causes

  • 1Power surge: electrical spikes damaging memory logic.
  • 2Corrupted jobs: print data packets causing a RAM buffer overflow.
  • 3Capacitor failure: aging electronic components on the logic board.
  • 4Firmware crash: failed update cycle causing boot failure.

Solutions

Quick Diagnosis

The C0004 error manifests as a complete system lock upon startup. If the device freezes on a specific screen, a corrupted print job likely saturated the memory cache.

Step-by-Step Solution

  1. Perform hard power reset: Turn off the printer and unplug both the power and networking cables for 5 minutes.
  2. Clear cache: If access is permitted, enter the maintenance menu to clear pending print jobs.
  3. Reconnect safely: Plug the device directly into a wall outlet, avoiding faulty voltage stabilizers.

Maintenance and Prevention

Always use a reliable surge protector to safeguard the control board from voltage spikes. Keeping the system firmware up to date also prevents cache management issues.

When to Call a Technician

If the error persists after a hard power reset, the main control board may require physical replacement due to component failure.
