Product : imageRUNNER C3100 / C3170 Title : E021-000x Error Code Error :
E021-000x Error Code: Developing rotary does not rotate and abnormal noise comes from motor.
E021 can be displayed when an error occurs in the developing rotary.
The detail codes are:
0001: The developing rotary home position cannot be detected.
0002: The intervals of flag detection during rotation is too short or long.
0003: The sensor does not detect the flag when the developing rotary stops at development point
As a result of inspection, it was found that the DC Controller PCB was unable to control the motor because it was faulty.
Workaround :
1. Check whether or not the developing rotary receives any physical load.
Rotate the developing rotary in a counterclockwise direction by hand to see whether it rotates smoothly. If any abnormality is found, eliminate the root cause. No problem is found, go to the Step 2.
2. Make sure that the connectors are securely fitted between J313 on the DC Controller PCB and the Rotary Motor (M8) or there is no pinched wire. No problem is found, go to the Step 3.
3. Replace the DC Controller PCB with a new one. If the symptom still recurs, go to the Step 4.
4. Replace the Rotary Motor with a new one.
DC Controller PCB: FG3-3846-030
Rotary Motor: FM2-0080-000
I went to an IRC2570 yesterday and the customer had inserted the yellow toner container BACKWARDS....broke the shutter on the dev....so one hour's labour+dev+toner and they were $1500 poorer at the end of it all.
