• Code: SC301
• Description: AC charge output error 2: M
  An interrupt checks the status of the power pack every 2 ms. This SC is issued if the BCU detects a short in the AC charge for black, magenta, cyan, or yellow (V = 0, for example) for 500 ms (250 times).
• Causes: • High voltage power supply • BCU defective • OPC unit defective

• Code: SC302
• Description: AC charge output error 3: C
  An interrupt checks the status of the power pack every 2 ms. This SC is issued if the BCU detects a short in the AC charge for black, magenta, cyan, or yellow (V = 0, for example) for 500 ms (250 times).
• Causes: • High voltage power supply • BCU defective • OPC unit defective

• Code: SC303
• Description: AC charge output error 4: Y
  An interrupt checks the status of the power pack every 2 ms. This SC is issued if the BCU detects a short in the AC charge for black, magenta, cyan, or yellow (V = 0, for example) for 500 ms (250 times).
• Causes: • High voltage power supply • BCU defective • OPC unit defective

• Code: SC312
• Description: Charge, development error 1: K
  500 ms after the black, magenta, cyan, and yellow drums start to rotate, the machine starts to monitor the AC current feedback at 8 ms intervals. This is SC is issued if the feedback for the charge unit of any color drops below 0.5V for 400 ms (50 consecutive readings).
• Causes: • Make sure that the settings of SP2202 are at the defaults. • Defective charge roller • Defective power pack

• Code: SC313
• Description: Charge, development error 2: M
  500 ms after the black, magenta, cyan, and yellow drums start to rotate, the machine starts to monitor the AC current feedback at 8 ms intervals. This is SC is issued if the feedback for the charge unit of any color drops below 0.5V for 400 ms (50 consecutive readings).
• Causes: • Make sure that the settings of SP2202 are at the defaults. • Defective charge roller • Defective power pack

• Code: SC314
• Description: Charge, development error 3: C
  500 ms after the black, magenta, cyan, and yellow drums start to rotate, the machine starts to monitor the AC current feedback at 8 ms intervals. This is SC is issued if the feedback for the charge unit of any color drops below 0.5V for 400 ms (50 consecutive readings).
• Causes: • Make sure that the settings of SP2202 are at the defaults. • Defective charge roller • Defective power pack

• Code: SC315
• Description: Charge, development error 4: Y
  500 ms after the black, magenta, cyan, and yellow drums start to rotate, the machine starts to monitor the AC current feedback at 8 ms intervals. This is SC is issued if the feedback for the charge unit of any color drops below 0.5V for 400 ms (50 consecutive readings).
• Causes: • Make sure that the settings of SP2202 are at the defaults. • Defective charge roller • Defective power pack

• Code: SC316
• Description: AC bias charge adjustment error 1: K
  An average value of 8 ms/cycle could not be attained for Vpp (AC charge bias) within 15 attempts. -or- The output of the AC charge boosted Vpp over 2.8 kV.
• Causes: • Charge roller dirty • Charge roller defective • Bias terminal connection at the PCU receptacle is dirty or defective
