01
Content
Main motor lock detection
Detail
The main motor does not rotate.
After rotation of the main motor, the motor lock
signal is detected for 1 sec or more.
During rotation of the main motor, the motor
lock signal is detected for 1 sec.
When the main motor is stopped, the motor
lock signal is not detected for 5sec or more.
(Though the motor is stationary, it is judged as
stable rotation.)
Cause
Main motor unit abnormality
Improper connection or disconnection the main
motor and the harness.
MCU PWB abnormality
Check
and
remedy
Use SIM 25-01 to check the main motor
operations.
Check connection of the main motor harness/
connector.
Replace the main motor.
Replace the MCU PWB.
31
Content

Sampling is performed in 50msec interval, and
the normal signal cannot be detected 5 times
continuously in 1 sec.
Cause
Fan trouble or harness contact trouble and
disconnection
Check
and
remedy
Use SIM05-02 to check the operations of the
fusing fan motor.
Heck connection of the fan harness and the
connector.
Replace the fan.
Replace the MCU PWB.
32
Content

the normal signal cannot be detected 5 times
continuously in 1 sec.
Cause
Fan trouble or harness contact trouble and
disconnection
Check
and
remedy
Check connection of the fan harness and the
connector.
Replace the fan.
Replace the MCU PWB.
