  • 4Lockup due to excessive overheating (friction).

Solutions

Quick Diagnosis

If the unit makes a 'straining' sound before showing C450, the motor is trying to turn but something is holding it. It is vital to disconnect the machine before attempting any manual roller rotation.

Step-by-Step Solution

  1. Physical inspection: Verify that the fuser unit rotates smoothly by hand.
  2. Gear cleaning: Remove paper scraps or hardened toner that might be blocking the side gears.
  3. Reboot: Power down and restart to reattempt the boot sequence.
  4. Connection check: Ensure the motor harness is firmly connected to the power board.

Prevention and Maintenance

Periodically lubricate main gears and keep the fuser unit free from toner spills via professional preventative maintenance.

When to Call a Technician

Error C450 implies a critical mechanical failure. If the motor still won't turn after clearing blocks, the stepper motor must be replaced.
