4) the black patch sensor is located on the black drum unit , when you remove the full assembly , the grey plastic on the front ( have 1 screw and 1 connector) removed and open the shutter and clean it with cotton swabs and alcohol. Be carefull not to damage the drum .
5) I prefer to open the door when trying to stop the process to check the patches on itb . The photos are not clear but if they are ok , then it could be the patch sensor pcb on the right side of the engine .
You should check the pcb connections and if any pin is bent.
Reg. Patch driver pcb Fm0-2925-000
Reg. Patch sensor assembly Fm0-1449-010
But my thought if no power issue occurred , then it is not a pcb issue . Sensor assembly should not get defected.
The customer can print normaly , but might need to restart the printer several times to get color well registered.
