Timing of detection
The punch sliding unit is not slid after sliding request is sent.
The punch sliding unit home position sensor (S23) does not detect that
the unit is at its home position after the specified time when the unit is
returned to the home position, or this sensor does not detect that the
unit is out of its home position after the specified time when the unit is
released.
The punch sliding unit home position sensor (S23) does not detect that
the unit is at its home position after the specified time when the unit is
moved, or this sensor does not detect that the unit is at its home
position when the unit is released.
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 TP26 on the hole punch control PC board
(HP). Then check that the measured voltage is 1V or lower when not
shielded and within the range of 5V
±
5% when shielded. If the voltage 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. (Hole
punch control PC board (HP): CN3, CN5, CN6)
If the error still occurs after replacing the motor, sensor and
connectors, exchange the hole punch control PC board (HP).
Sideways adjustment motor (M2) abnormality: Sideways
adjustment motor is not rotating or puncher is not shifting
normally.
If there is any paper remaining on the transport path, remove
the paper.
• If there is mechanical problem when the sideways
adjustment motor (M2) is rotated, fix the mechanism.
• Check the connectors and harnesses between the hole
punch control PC board (HP) and sideways adjustment
motor (M2).
• Sensor check
• Harness check
