• Code: SC362
• Description: IMAC (Image Memory Access Controller) error
  At the IPU, an error was detected during data compression with the GAIMAC ASIC or during data transfer to memory.
• Causes: • Software error, IPU defective. Update the firmware. If this does not solve the problem, replace the IPU board.

• Code: SC365
• Description: Image processing parameter error
  An image processing data file not stored in the memory was required when writing started due to software error.
• Causes: Software error. Replace software (all three firmware modules).

• Code: SC391
• Description: Development bias error
  A development bias feedback voltage of less than 0.25V was detected for more than 200 ms while the PWM duty value was more than 1% (development bias leak).
• Causes: • Bias power pack defective • Bias cable defective • Poor bias cable connection • Bias leak

• Code: SC401
• Description: Transfer corona leak error
  A transfer corona feedback voltage of less than 0.25V was detected for more than 200 ms.
• Causes: • T&S power pack defective. • Transfer corona cable defective. • Poor transfer corona cable connection. • Dirty T&S corona unit caused leak

• Code: SC411
• Description: DC separation corona current leak
  A dc separation feedback voltage of less than 0.5V was detected after more than 200 ms while the PWM duty value was more than 17%.
• Causes: • T&S power pack defective. • Paper separation current cable defective. • Poor paper separation current cable connection.

• Code: SC440
• Description: Drum drive motor lock
  The motor lock signal is on longer than 5 s while the drum drive motor is on.
• Causes: • Drive mechanism overload. • Motor defective.

• Code: SC441
• Description: Development drive motor lock
  SC441-1 Development drive motor lock signal is low longer than 5 s when the development motor stops. SC441-2 Development drive motor lock signal is high longer than 5 s when the development motor rotates.
• Causes: • Drive mechanism overload • Motor defective • Motor disconnected

• Code: SC506
• Description: Registration motor lock
  The registration motor lock signal is high longer than 5 s during operation.
• Causes: • Drive mechanism overload. • Motor defective.
