• Code: 2564-132.02
• Description: Black TCR sensor failure
  TDS baseline too high.
• Causes: • Toner density sensor (PS13) • Controller board (CTLB)
• Remedy: 1 Remove the transfer roll, and then check for loose toner blocking PS13. Clean the sensor if any abnormality is found. 2 Check PS13 for proper operation. Reinstall the actuator if any abnormality is found. 3 If it still cannot move freely, then replace PS13. 4 Check the cable JTDS for proper connection. Reseat the cable if any abnormality is found. 5 Check the cable JTDS for damage and pinch points. Replace PS13 if any abnormality is found. 6 Replace the CTLB.
