Check Wiring and PCB's for physical damage.
1. If the E025 error or the above symptoms occurs, detach the hopper of the color involved and
clean the sensors [A] through [F] (FG8-5848-000).
Refer to the Service Manual for the procedure of detaching the Hopper of each color.
Note: If the symptom recurs even after cleaning all sensors, replace the sensors [A] through [F]
(WG8-5848-000) of the color involved. Each Hopper (Y, M, C, BK) contains 3 sensors, for a
total of 12 sensors. The parts numbers are the same (WG8-5848-000).
Method of cleaning the sensors [A] through [F]
Bk hopper
Step1: Vacuum out the Hopper thoroughly to prevent toner spill and soiling of the work area.
Turn the Hopper over, remove the screw [1], disconnect the connector, and remove the
sensor holder [2].
Step2: Remove the sensor [A] from the sensor holder [2].
