Solutions

Quick Diagnosis

C-4101 causes an immediate system lockout. If you hear a high-pitched whining sound followed by the error code, the polygon motor in the laser unit has likely jammed or failed.

Step-by-step Solution

  1. Reboot: Power off and unplug the machine for 15 minutes.
  2. Check Firmware: Perform a firmware update if the error is intermittent.
  3. Environment: Ensure the printer sits on a flat, vibration-free surface.
  4. Test Print: Restart and run an internal engine test.

Prevention and Maintenance

While wear and tear is common, using a UPS (Uninterruptible Power Supply) can prevent electrical damage to the sensitive control boards of the LSU.
