  • 1Mechanical jam in the transport assembly.
  • 2Internal motor failure or circuit overload.
  • 3Paper debris preventing motor rotation.
  • 4Faulty motor speed sensor.

Solutions

Diagnostic

The 04 code denotes that the main motor drive circuit has detected an error. If the printer feels heavy or blocked, check for jammed paper inside the front housing.

Step-by-step solution

  1. Disconnect the printer from the power source.
  2. Open the front panel and pull out the drum/toner cartridge.
  3. Check for any jammed paper fragments in the delivery rollers.
  4. Clean any excess toner dust from the internal pathways.
  5. Reinstall and plug back into a power outlet.

Maintenance

Routine internal vacuuming helps prevent the build-up of fine particles that can jam sensitive gear assemblies.

When to call a technician

If the motor makes grinding noises or the error returns after clearing all paths, the main logic board or motor assembly is likely compromised.
