• Code: SC442
• Description: Image transfer power pack error: C
  An interrupt checks the status of the power pack every 10 ms. This SC is issued if the VBCU detects a short in the power pack for K, M, C, or Y.
• Causes: • Transfer belt damaged, insulation damaged • Insulation on high voltage cable damaged • Another hot point inside the machine has damaged insulation • Insulation around high-voltage power supply damaged

• Code: SC443
• Description: Image transfer power pack error: Y
  An interrupt checks the status of the power pack every 10 ms. This SC is issued if the VBCU detects a short in the power pack for K, M, C, or Y.
• Causes: • Transfer belt damaged, insulation damaged • Insulation on high voltage cable damaged • Another hot point inside the machine has damaged insulation • Insulation around high-voltage power supply damaged

• Code: SC445
• Description: Image transfer motor error
  The control board of the ITB motor belt generated signals that indicate there is problem with the image transfer belt motor.
• Causes: • ITB motor defective • ITB control board defective • ITB overloaded • Encoder strip on the edge of the ITB damaged.

• Code: SC446
• Description: ITB lift motor error
  The state of the ITB lift sensor does not change its state (switching from off to on or vice versa), even after the ITB lift motor starts rotating.
• Causes: • ITB lift sensor dirty, disconnected, defective • ITB lift motor disconnected, defective • ITB sensor defective • ITB lift motor defective

• Code: SC447
• Description: Image transfer roller position error
  The machine checks for the presence of the K STC and the checks the status of the K image transfer roller lift sensor after the door is closed.
• Causes: • Transfer belt release lever down • Lift sensor connector loose, broken, dirty • Lift sensor defective

• Code: SC450
• Description: Transfer power pack output error
  An interrupt checks the status of the power pack every 2 ms. This SC is issued if the VBCU detects a short in the power pack 250 times at T2 within 500 ms.
• Causes: • Damaged insulation on the high-voltage supply cable • Damaged insulation around the highvoltage power supply. • Check SIOB harness connections • SIOB defective

• Code: SC452
• Description: PTR lift mechanism error
  The PTR was not detected at the home position within 2 sec. after the PTR lift motor turned on.
• Causes: • PTR HP sensor dirty, disconnected, defective • PTR lift motor disconnected, defective

• Code: SC455
• Description: PTR motor error
  The lock signal from the paper transfer motor was not detected within 1 sec. after the motor switched on.
• Causes: • Motor disconnected • PTR shaft locked, needs cleaning, blocked by obstruction • Drive shaft of the ITB locked and overloaded, needs cleaning, or blocked by obstruction • DRB disconnected, defective
