Measures
Fix any mechanical problem occurring when the actuator is moved.
Check if there is a disconnection of the connector, incorrect
installation or breakage of the movable tray paper-full sensor (S16).
If there is, reinstall the sensor correctly or replace it.
Check if the connector (CN12) on the finisher controller PC board is
disconnected from the movable tray paper-full sensor (S16) and the
harnesses are open circuited. Correct if so.
Remark
Timing of detection
The stack top holding/detecting sensor (S11) and the paper holding
home position sensor (S12) do not detect the position of the top of the
stack of paper in the specified time when the paper holding lever is
moved to the paper detection position.
Checking and measures
Check if the electrical continuity of the coil is normal. If electricity is not
conducted, replace the solenoid.
Measure the voltage on TP13 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 TP71 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 connector. (Finisher
control PC board (FIN): CN3, CN4)
If the error still occurs after replacing the solenoid, sensors and
connector, exchange the finisher control PC board (FIN).
Front alignment motor abnormality: The front alignment motor is
not rotating or the front alignment plate is not moving normally.
