• Code: 54.0X.0C
• Display: 54.XX.YY Error
• Description: A sensor error has occurred
  Density sensor out of range error or Dhalf calibration failure X = 0 black, X = 1 cyan, X = 2 magenta, X = 3 yellow
• Remedy: 1. Check the supplies status page to make sure the toner cartridges are not past their useful life. 2. Check the ITB for damage. 3. Make sure the CPR sensor is not contaminated with toner or paper dust. Clean the sensor with compressed air and soft brush. 4. If error persists, replace the registration sensor assembly.
