ERROR CODE AND TROUBLESHOOTING
8 - 167
[CC53] Punch waste full sensors (S41 and S42) abnormality
MJ-1033
[CC54] Abnormality of paper detection sensors (S24 and S25)
MJ-1032
[CC54] Abnormality of trailing edge detection sensors (S39 and S40) and horizontal registration
detection sensors (S39 and S40)
MJ-1033
Error Timing of detection
Punch waste full sensor 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.
Probable cause Checking and measures
Punch waste full sensors (S41 and
S42) abnormality 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.
Faulty cables and connectors 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)
Hole punch control PC board (HP)
abnormality If the error still occurs after replacing the sensors and the
connectors, exchange the hole punch control PC board (HP).
Error Timing of detection
Paper detection sensor (S24/S25)
adjustment erro The adjustment of the paper detection sensors (S24 and S25) has
been failed.
。
Probable cause Checking and measures
Paper detection sensors (S24 and
S25) abnormality 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.
Faulty cables and connectors 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)
Hole punch control PC board (HP)
abnormality
If the error still occurs after replacing the sensors and the connectors,
exchange the hole punch control PC board (HP).
Error Timing of detection
Trailing edge detection sensor
Horizontal registration detection
sensor After the sensor output adjustment, the input value is lower than

higher than 3.5V against the output value of 0.1V.
