Description: Error in M Developing Assembly
Error in signal lower limit with ATR sampling detected value
Remedy: 1. Check if the ATR Sensor Connector is disconnected. 2. Check short-circuit of the ATR Sensor (TS6) Harness. 3. Replace the Developing Assembly.
Code: E020-0291
Description: Error in M Developing Assembly
Error in signal upper limit with ATR sampling detected value
Remedy: 1. Check toner leak from the Toner Buffer Unit. 2. Check toner level in the Toner Container. 3. Replace the Developing Assembly. 4. Check short-circuit of the harness with the Toner Buffer Supply Sensor (PS2).
Code: E020-02B0
Description: Error in M Developing Assembly
TD ratio lower limit error at the time of print sequence (Large amount of toner in the Developing Assembly)
Remedy: Go through the following: DISPLAY > DENS > DENS-M; if DENS-M is slightly higher than 5.0%, output 10 sheets of solid image with the color causing the error (to reduce T/D ratio). See the Service Mode again to see if the problem is improved. Remedy is complete if it’s improved. If not, perform the following remedy work. 1. Check if the ATR Sensor (TS6) Connector is disconnected. 2. Check short-circuit of the ATR Sensor Harness. 3. Replace the Developing Assembly.
Code: E020-02B1
Description: Error in M Developing Assembly
TD ratio upper limit error at the time of print sequence (Small amount of toner in the Developing Assembly)
Remedy: 1. Output 10 sheets of white (blank) sheets (to increase T/D ratio). 2. Check toner leak from the Toner Buffer Unit. 3. Check toner level in the Toner Container. 4. Replace the Developing Assembly. 5. Check short-circuit of the harness of the Toner supply sensor (PS2).
Code: E020-0330
Description: Error in C Developing Assembly
The average of ATR reference value was lower than the specified value at the time of ATR Sensor initialization
Remedy: 1. Check short-circuit of the ATR Sensor (TS7) Harness. 2. Replace the Developing Assembly.
Code: E020-0331
Description: Error in C Developing Assembly
The average of ATR reference value was higher than the specified value at the time of ATR Sensor initialization
Remedy: 1. Check if the ATR Sensor (TS7) Connector is properly connected. 2. Check short-circuit of the ATR Sensor Harness. 3. Replace the Developing Assembly.
