• Code: 300
• Description: Charge Corona Output Error
  The charge-corona feedback voltage was less than 1 V for more than 200 ms.
• Causes: Replace the charge corona unit. • Replace the high voltage cable. • Clean or replace the corona wire. • Check the CGB power pack fuse, connection. • Replace the CGB power pack.

• Code: 305
• Description: Charge Corona Wire Cleaner Error
  The charge wire cleaner did not a) come from the home position within 5 s, or b) did not go back to the home position in 3.7 s or less. This is because of wire cleaner overload.
• Causes: • Switch the main power switch off/on. • Check the wire cleaner unit for a blockage or broken parts.

• Code: 330
• Description: Writing ASIC Signal Error
  At power on, the stamp function could not start.
• Causes: • Check the setting of SP5137. If the stamp option is installed, this SP must be enabled. If the stamp option is not installed, this SP must be disabled. • Check the stamp board connections. • Replace the defective stamp board.

• Code: 360
• Description: Hard Disk Connection Error
  The machine could not detect the HDD connection.
• Causes: • Check the connections between the HDD and hard disk controller. • Check the HDD power connector. • Replace the HDD. • Replace the MCU.

• Code: 361
• Description: Hard Disk Read Errors
• Causes: • Do SP4960-1 (HDD Media Check). • Do SP4906 003 to format the HDD. • If formatting the HDD fails, replace the HDD.

• Code: 362
• Description: IMAC (Image Memory Access Controller) error
  During data transfer in memory at the IPU, an error occurred during data compression with ASIC (IMAC). The ASIC controls data compression.
• Causes: • Update the firmware. • If the firmware update does not stop the problem, replace the IPU board. • Update all software modules if this problem continues.

• Code: 380
• Description: MSU Output Error
  Just after the machine was switched on, it could not detect that the MSU (Memory Super-charger Unit) was set.
• Causes: • Replace the IPU.

• Code: 392
• Description: Development Bias Error
  The development bias feedback voltage was less than 0.5 V for longer than 200 ms while the PWM duty value was more than 5% (indicating a development bias leak).
• Causes: • Check the MCU connectors. • Check the harness on the MCU for damage. • Replace the high voltage cable. • Replace the CGB power pack.
