- 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.
Cause
Electrical power was not supplied to the Backside Driver PCB.
Field Remedy
When the symptom occurs after performing a work by removing the lower left cover, check to see if the jumper connector or the connector in the main body
side is disconnected; if so, re-connect the disconnected connector.
Reference: In the Service Manual, the following 4 faults are listed as conceivable causes.
1. A soiling on the rotary HP sensor (PS21) found in the rear side of the P-Kit and poor contact of J208 connector.
2. A fault in the rotary HP sensor (PS21).
3. Poor contact of J3802 or J3810 connector of the Backside Driver PCB.

[ Case in the field ]
Description
Since the error code "E025-0004" was indicated after replacement of the drum, the drum was pull out and then re-inserted for solution.
- E025-0004 can be displayed when toner is supplied with the hopper shutter closed.
Cause
When closing the hopper, it was not closed completely.
Field Remedy
1. Open the hopper assembly, and then close it slowly so that either sides of the assembly fit simultaneously.
2. If the symptom still occurs, pull out the drum and then insert it again.
3. If the symptom still occurs, re-fit the connector of the hopper shutter switch (SW15).
4. If the symptom still occurs, replace the hopper shutter switch (SW15) with a new one.
