ERROR CODE AND TROUBLESHOOTING
Skew adjustment motor (M1) abnormality: Skew 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 skew adjustment
motor (M1) is rotated, fix the mechanism.
• Check the connectors and harnesses between the hole
punch control PC board (HP) and skew adjustment motor
(M1).
• Sensor check
• Harness check
Timing of detection
The adjustment of the paper detection sensors (S24 and S25) has
been failed.。
Checking and measures
Measure the voltage on pin CN6.8 on the hole punch control PC board
(HP). Then check that the measured voltage is 3.0V or higher when
not shielded and 1.2V or lower when shielded. If the voltage does not
fall within the range mentioned, replace a couple of PC boards on
either the light-receiving side or the light-emitting side.
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): CN4, CN6)
If the error still occurs after replacing the sensors and the connectors,
exchange the hole punch control PC board (HP).
