Symptom

E025-0x02 Timeout error of the supply screw rotation detection sensor

Symptom
E025-0x02 occurred.
- E025-0x02: Block supply timeout error. The toner supply screw rotation sensor cannot detect rotation of
the screw. (x=1: Y, 2: M, 3: C, 4: Bk)
Cause
It is considered that the cause is either of the following:
a) Disconnection of the connector for the stirring supply motor, breaking of wire, and damage on the hopper
driver PCB
b) Pinching of the harness tie-wrap for Bk hopper
c) Clogging of toner in the toner supply pipe leading to the developing assembly
d) Distortion of the unit due to the wrong screw used to install the hopper unit (Bk) or due to the wrong order
in which the screws are installed
e) Distortion of the unit due to the wrong order in which the screws are installed in the hopper unit (Y)/(M)/(C)
f) Contamination of the rotation detection sensor
g) Failure in the stirring screw drive motor (i.e., DC motor)
Service work
Different measures should be taken depending on the location of the cause. Make sure which of the
following is the cause, and take appropriate actions. All the actions at step c) and the subsequent steps
require removal of the hopper unit. For the removal procedure, refer to the FAQ below.
FAQ title: "E025-0x10 due to the bottle not inserted or removed and no detection of the home position
detection signal"
Step b) Removal of the hopper unit (Bk)
Step c) Removal of the hopper unit (Y)/(M)/(C)
