Timing of detection
The turning OFF of the front alignment plate home position sensor (S9)
is not detected in the specified time when the front alignment plate is
moved from a point where this sensor is turned ON to one point where
this sensor is turned OFF.
The turning ON of the front alignment plate home position sensor (S9)
is not detected in the specified time when the front alignment plate is
moved from a point where this sensor is turned OFF to one point
where this sensor is turned ON
Checking and measures
Check if the electrical continuity of the coil is normal. If electricity is not
conducted, replace the motor.
Measure the voltage on pin CN8.3 on the finisher control PC board
(FIN). Then check that the measured voltage is 1V or lower when not
shielded and within the range of 3.3V
does not fall within the range mentioned, replace the sensor.
Check if the electrical continuity between the connector
terminals is normal. If electricity is not conducted, replace the
connectors. (Finisher control PC board (FIN): CN2, CN8)
If the error still occurs after replacing the motor, sensor and
connectors, exchange the finisher control PC board (FIN).
Timing of detection
The turning ON of the movable tray upper limit sensor (S16) is
detected.
Checking and measures
Check if the electrical continuity of the coil is normal. If electricity is not
conducted, replace the motor.
Measure the voltage on pin CN7.3 on the finisher control PC board
(FIN). Then check that the measured voltage is 1V or lower when not
shielded and within the range of 3.3V
does not fall within the range mentioned, replace the sensor.
Measure the voltage on TP35 on the finisher control PC board (FIN).
Then check that the measured voltage is 1V or lower when not
shielded and within the range of 3.3V
does not fall within the range mentioned, replace the sensor.
Measure the voltage on TP28 on the finisher control PC board (FIN).
Then check that the measured voltage is 1V or lower when not
shielded and within the range of 3.3V
does not fall within the range mentioned, replace the sensor.
Measure the voltage on TP29 on the finisher control PC board (FIN).
Then check that the measured voltage is 1V or lower when not
shielded and within the range of 3.3V
does not fall within the range mentioned, replace the sensor.
