Konica Minolta bizhub C1085 error C-6752: Scanner Fail

The Konica Minolta bizhub C1085 error C-6752 indicates a failure within the scanner's exposure unit. This happens when the machine's internal system fails to detect the scanner lamp's lighting or when the scanner carriage itself cannot reach its 'home' position to calibrate properly.

  • 3Home position sensor debris.
  • 4Internal data cable damage (flex cable).

Solutions

Quick Diagnosis

If you see C-6752, the machine is unable to light up the scanner lamp or move the carriage. Observe the scanner glass; if the light does not flicker during start-up, the internal LED array or the driving motor is likely faulty.

Step-by-step Solution

  1. Shutdown: Power off and unplug the unit for 10 minutes to reset motion controls.
  2. Check for Obstructions: Ensure no debris is jammed in the carriage rail path.
  3. Re-initiate: Power on and watch for the scanner lamp cycling colors during the boot process.

Prevention and Maintenance

Keep the scan surface free of adhesives. Power-cycling the machine occasionally ensures the scanner carriage resets its position properly. Do not force the scanner door if it seems stuck, as this can break the internal rail system.

When to Call a Technician

If the lamp does not turn on, the LED assembly needs replacement. If the carriage makes grinding sounds, the motor or belt requires servicing. This is an advanced repair requiring disassembly of the scanner unit.
