Remedy: 1.Turn OFF and then ON the power. 2.Replace the ITB Unit.
Code: E020-0090
Description: ATR Sensor (Y) error or toner supply error
The average of ATR Sensor (Y) detection value is the specified value or lower.
Remedy: 1. Check if the Drum Unit (Y) is installed. 2. Check the Drum Unit Relay PCB (Y) (UN26) 3. Check the Drum Unit Memory PCB (Y) (UN30) 4. Check the harness/connector between the DC Controller PCB (UN09/ J25) and the Drum Unit Relay PCB (Y) (UN26). 5. Replace the Drum Unit (Y). 6. Replace the DC Controller PCB (UN09)
Code: E020-0091
Description: ATR Sensor (Y) error or toner supply error
The average of ATR Sensor (Y) detection value is the specified value or higher.
Remedy: 1. Check if the Drum Unit (Y) is installed. 2. Check the Drum Unit Relay PCB (Y) (UN26) 3. Check the Drum Unit Memory PCB (Y) (UN30) 4. Check the harness/connector between the DC Controller PCB (UN09/ J25) and the Drum Unit Relay PCB (Y) (UN26). 5. Replace the Drum Unit (Y). 6. Replace the DC Controller PCB (UN09)
Code: E020-00B0
Description: ATR Sensor (Y) error or toner supply error
T/D ratio detected by the ATR Sensor (Y) (UN39) is equal to or higher than the specified value (high density)
Remedy: 1. Check if the Drum Unit (Y) is installed. 2. Check the Drum Unit Relay PCB (Y) (UN26) 3. Check the Drum Unit Memory PCB (Y) (UN30) 4. Check the harness/connector between the DC Controller PCB (UN09/ J25) and the Drum Unit Relay PCB (Y) (UN26). 5. Replace the Drum Unit (Y). 6. Replace the DC Controller PCB (UN09)
Code: E020-00B1
Description: ATR Sensor (Y) error or toner supply error
Error in detected delta T/D ratio T/D ratio detected by the ATR Sensor (Y) (UN39) is equal to or lower than the specified value (light density)
Remedy: Possible cause: overload with the motor or motor failure 1. Check conduction with FU2 on the DC Controller PCB (UN09) 2. Check the harness/connector between the DC Controller PCB (UN09/ J23) and PS06. 3. Replace the DC Controller PCB (UN09) 4. Check the Hopper Unit (Y) 5. Replace the Hopper Unit (Y).
Code: E020-0120
Description: ATR Sensor (M) error or toner supply error
Error in detected TD ratio. The average of ATR reference value is the specified value or lower at the time of ATR Sensor (M) initialization.
Remedy: 1. Check if the Drum Unit (M) is installed. 2. Check the Drum Unit Relay PCB (M) (UN27). 3. Check the Drum Unit Memory PCB (M) (UN31). 4. Check the harness/connector between the DC Controller PCB (UN09/ J25) and the Drum Unit Relay PCB (M) (UN27). 5. Replace the Drum Unit (M). 6. Replace the DC Controller PCB (UN09)
