Gripper arm motor home position detection error
Timing of detection
The turning OFF of the gripper arm home position sensor (S13) is not
detected in the specified time when the gripper arm is exited.
The turning ON of the gripper arm home position sensor (S13) is not
detected in the specified time when the gripper arm is returned to its
home position.
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 CN10.8 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 TP27 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.
If the error still occurs after replacing the motor, sensors and
connectors, exchange the finisher control PC board (FIN).
If the error still occurs after replacing the motor, sensors and
connectors, exchange the finisher control PC board (FIN).
