E020 0290 05 Title Error in M Developing Assembly
Description 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.
E020 0291 05 Title Error in M Developing Assembly
Description 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).
E020 02B0 05 Title Error in M Developing Assembly
Description 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.
E020 02B1 05 Title Error in M Developing Assembly
Description 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).
E020 0330 05 Title Error in C Developing Assembly
Description 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.
