• Code: E051-0001
• Description: The home position of the side registration sensor (S32) cannot be detected. The home position cannot be detected when 24-V power is turned on in response to the turning on of the main power switch or the opening and closing of the front cover/delivery assembly cover/ face-down delivery unit.
• Causes: The side registration sensor (S32) is faulty. The side registration motor (M17) is faulty. The duplex driver PCB is faulty. The DC controller PCB is faulty.

• Code: E070-
• Description: The transfer belt sensor (S51) continues to detect the home position for the transfer belt.
• Causes: The transfer belt sensor (S51) is faulty. The transfer belt is deformed. The transfer high-voltage PCB is faulty. The DC controller PCB is faulty.

• Code: E070-0001
• Description: The transfer belt sensor (S51) cannot detect the home position of the transfer belt.
• Causes: The transfer belt sensor (S51) is faulty. The transfer belt is deformed. The transfer high-voltage PCB is faulty. The DC controller PCB is faulty.

• Code: E073-0001
• Description: The transfer unit cannot be detected when the front door is closed.
• Causes: The transfer drawer connector has poor contact. The transfer unit is absent.

• Code: E074-0001
• Description: The output of the transfer swing sensor (S49, S50) does not change even when the transfer unit is swung.
• Causes: The transfer swing sensor (S49, S50) is faulty. The transfer swing clutch (CL23) is faulty. The pickup main motor (M1) is faulty. The serial driver PCB is faulty.

• Code: E196
• Description: X=01: Y, X=02: M, X=03: C, X=04: Bk (X indicates the developing assembly color) YY=AA, 55, 00 (data in the presence of an error) 9XYYDrum kit cartridge EEPROM check error A101 System controller PCB DIMM (absent) A102 System controller PCB memory type (not SDRAM) A103 System controller PCB memory sequential error A104 System controller PCB memory capacity error (including a mix of 64 M and 128 M) A105 System controller PCB memory type (not of recommended type) A106 System controller PCB memory capacity error (duplex model, inadequate memory) A2ZZ RCON
• Causes: A memory error has occurred in the EEPROM.

• Code: E197
• Description: X=0: System controller PCB side 2: DC controller PCB side Ex01 Serial reception error (during data reception) Ex02 Reset on CPU of other party (during data reception) Ex03 During processing of transmission/reception data (during data reception) Ex04 Serial reception error (during standby) Ex05 Reset on CPU of other party (during standby) Ex06 During processing of transmission /reception data (during standby) 020F Connection time-out
• Causes: An error has occurred in communication among PCBs within the printer unit.

• Code: E202
• Description: During a home position search, the mirror base does not return to the home position within a specific period of time.
• Causes: The mirror base malfunctions.
