ERROR CODE AND TROUBLESHOOTING
Timing of detection
After the sensor output adjustment, the input value is lower than
1.2V against the output value of 2.8V, or the input value is
higher than 1.5V against the output value of 0.1V.
Checking and measures
Measure the voltage on TP49 on the hole punch control PC
board (HP). Then check that the measured voltage is 1V or
lower when not shielded and 2.5V or higher 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): CN5)
If the error still occurs after replacing the sensors and the
connectors, exchange the hole punch control PC board (HP).
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).
Timing of detection
After the sensor output adjustment, the input value is lower than
3.2V against the output value of 2.8V, or the input value is
higher than 3.5V against the output value of 0.1V.
