ERROR
E021-0001 : due to faulty rotary HP sensor (PS21)



Description
In the field, altough the developing rotary rotated, but due to faulty rotary HP sensor (P21) attached in the rear side of P kit assembly, E021-0001 was displayed.
- E021-0001 can be displayed when the developing rotary HP cannot be detected because of the rotary HP sensor error, incorrect wiring of the DC controller PCB, or lack of torque due to excess load to the developing assembly.


Field Remedy
1. Enter Service Mode > COPIER > I/O > DC-CON > P002, check whether the bit8 change "0" and "1" when rotary rotates. In the case, it kept in "0" without changing.
2. If bit8 doesn't change, clean the rotary HP sensor and refit connector J208.
3. Refit the connector J3802/J3810 of the backside driver PCB assembly.
4. Refit the connector J1198 of the DC Controller PCB.
5. If the symptom still occurs, replace rotary HP sensor with a new one.
[Reference] The sensor used in rotary HP sensor is the same as sensor used in toner supply detection sensor (PS68 to PS 71). Before replacement, to determine whether the sensor can properly work or not, switch with one of those sensors.
