• Code: SC442
• Description: Image transfer power pack error 3: C
  An interrupt checks the status of the power pack every 2 ms. This SCis issued if the BCU detects a short in the power pack for K, M, C, or Y 250 times within 500 ms.
• 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 • IOB damaged

• Code: SC443
• Description: Image transfer power pack error 4: Y
  An interrupt checks the status of the power pack every 2 ms. This SCis issued if the BCU detects a short in the power pack for K, M, C, or Y 250 times within 500 ms.
• 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 • IOB 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 front edge of the belt 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

• 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 BCU 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 high-voltage power supply.

• Code: SC455
• Description: PTR motor error
  The lock signal from the paper transfer motor is 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 (motor drive board) disconnected, defective

• Code: SC460
• Description: Separation power pack output error
  An interrupt checks the status of the power pack every 2 ms. This SCis issued if the BCU detects a short in the power pack 250 times at D(ac) within 500 ms.
• Causes: • Damaged insulation on the high-voltage supply cable • Damaged insulation around the high-voltage power supply.

• Code: SC484
• Description: Waste toner bottle full
  The toner full sensor goes HIGH for more than 500 ms, indicating that the waste toner bottle is full.
• Causes: • Remove waste toner bottle, empty it
