ERROR CODE AND TROUBLESHOOTING
8 - 159
Error Timing of detection
Movable tray shift motor (M1)
Stack top detection solenoid (SOL1)
Stack top detection sensor-1 (S1)
Stack top detection sensor-2 (S2
Movable tray lower limit sensor (S14) A locking signal is detected after the specified time
*
while the movable
tray is moving.
*
A locking signal is not monitored from the start driving the motor until
the specified time has passed.
The stack top position of paper is not detected after the movable tray
shift motor (M1) is driven in the specified time when the movable tray is
moved up.
The lower limit position of the stack top of paper is not detected after
the movable tray shift motor (M1) has been driven in the specified time
during the initial movement of the movable tray.
The turning OFF of the movable tray lower limit sensor (S14) is not
detected when the movable tray is moved from a point where this
sensor is turned ON to one point where this sensor is turned OFF after
the movable tray shift motor (M1) has been driven in the specified time.
Probable cause Checking and measures
Movable tray shift motor (M1)
abnormality Check if the electrical continuity of the coil is normal. If electricity is not
conducted, replace the moto
Movable tray lower limit sensor (S14)
abnormality Measure the voltage on TP17 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
±
5% when shielded. If the voltage does not fall within the range
mentioned, replace the sensor.
Faulty cables and connectors
Check if the electrical continuity among the connector terminals
is normal. If electricity is not conducted, replace the connectors.
(Finisher control PC board (FIN): CN4, CN10)
Finisher control PC board (FIN)
abnormality If the error still occurs after replacing the motor, sensors and
connectors, exchange the finisher control PC board (FIN).
Stack top detection solenoid (SOL1)
abnormality Check if the electrical continuity of the coil is normal. If electricity is not
conducted, replace the solenoid.
Stack top detection sensor-1 (S1)
abnormality Measure the voltage on TP11 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
±
5% when shielded. If the voltage does not fall within the range
mentioned, replace the sensor.
Stack top detection sensor-2 (S2)
abnormality Measure the voltage on TP20 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
±
5% when shielded. If the voltage does not fall within the range
mentioned, replace the sensor.
Faulty cables and connectors
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)
Finisher control PC board (FIN)
abnormality If the error still occurs after replacing the solenoid, sensors and
connector, exchange the finisher control PC board (FIN).
