E020 03F0 Title Error in toner density (C) at communication failure of the Drum Unit
Memory PCB (C)
Description Communication between the DC Controller PCB and the Drum Unit
Memory PCB (C) was not available, and the output value (SigR) of the
ATR Sensor (C) did not fall within the range from 50 or higher to 800 or
less for 2 consecutive times.
Remedy [Related parts]
• Harness between the DC Controller PCB (UN04/J162) and the Drum
Unit Relay PCB (Y) (UN10/J6003) (Unit of replacement: PROCESS
CONTROL PCB ASS'Y)
• Drum Unit (C) (Unit of replacement: DEVE_UNIT_C)
[Points to note at work]
• When checking the harness/cable or connector, perform the following
work.
1. Disconnect and then connect the connector to check that there is no
bent pin and cable disconnection.
2. Visually check that the harness is not caught or open circuit.
3. If there is any error, replace the corresponding harness/cable.
• If the Drum Unit Memory PCB (C) is soiled, clean it with a blower.
[Remedy] Check/replace the related parts.
E020 04A8 Title ATR Sensor (Bk) output error
Description The output value of the ATR Sensor (Bk) in the Drum Unit (Bk) did not fall
within the range from 10 or higher to 245 or less for 2 consecutive times
during printing.
Remedy [Related parts]
• ATR Sensor (Bk) (UN37) (Unit of replacement: P-UNIT_BK)
• Drum Unit (Bk) (Unit of replacement: P-UNIT_BK)
• Harness between the ATR Sensor (Bk) (UN37/J6024) and the Drum Unit
Memory PCB (Bk) (UN15/J6014) (Unit of replacement: P-UNIT_BK)
• Harness between the DC Controller PCB (UN04/J162) and the Drum
Unit Relay PCB (Bk) (UN11/J6004) (Unit of replacement: PROCESS
CONTROL PCB ASS'Y)
• DC Controller PCB (UN04) (Unit of replacement: DC CONTROLLER
PCB ASSEMBLY)
[Points to note at work]
• When checking the harness/cable or connector, perform the following
work.
1. Disconnect and then connect the connector to check that there is no
bent pin and cable disconnection.
2. Visually check that the harness is not caught or open circuit.
3. If there is any error, replace the corresponding harness/cable.
• If the Drum Unit Memory PCB (Bk) is soiled, clean it with a blower.
[Remedy] Check/replace the related parts.

E020 04B8 Title ATR Sensor (Bk) output error
Description a. The output value of the ATR Sensor (Bk) in the Drum Unit (Bk) did not
fall within the range from 10 or higher to 990 or less for 2 consecutive
times at initialization.
b. The output value did not exceed 140 although the control voltage of the
ATR Sensor (Bk) in the Drum Unit (Bk) was increased to 248 or higher,
or it did not fall below 140 although the voltage was decreased to 8 at
initialization.
Remedy [Related parts]
• ATR Sensor (Bk) (UN37) (Unit of replacement: P-UNIT_BK)
• Drum Unit (Bk) (Unit of replacement: P-UNIT_BK)
• Harness between the ATR Sensor (Bk) (UN37/J6024) and the Drum Unit
Memory PCB (Bk) (UN15/J6014) (Unit of replacement: P-UNIT_BK)
• Harness between the DC Controller PCB (UN04/J162) and the Drum
Unit Relay PCB (Bk) (UN11/J6004) (Unit of replacement: PROCESS
CONTROL PCB ASS'Y)
• DC Controller PCB (UN04) (Unit of replacement: DC CONTROLLER
PCB ASSEMBLY)

E020 04C0 Title Error in take-up of Sealing Member (Bk)
Description The patch output value (SigR) failed to be 900 or less during initialization
of the Drum Unit (Bk).
Remedy [Remedy] Replace the Drum Unit (Bk). (Unit of replacement: P-UNIT_BK)
