Error
Punch motor (M11)
Paper detection sensor (S24/S25)
Punch shaft home position sensor
(S26)
Rear punch shaft home position sensor
(S22)
Probable cause
Punch motor (M11) abnormality
Rear punch shaft home position sensor
(S22) abnormality
Punch shaft home position sensor
(S26) abnormality
Punch motor clock sensor (S20)
abnormality
Faulty cables and connectors
Hole punch control PC board (HP)
abnormality
[CC61] Punch motor (M3) home position detection error
MJ-1107/1108 (When MJ-6104 is installed)
* The [CC61] error occurs when the [E9F0] error occurs three times in succession or during the initial
operation.

Timing of detection
The paper detection sensors (S24 and S25) do not emit light after
specified time when they are selected
The level of the light-receiving amount is not lowered after the light-
emitting amount of the paper detection sensors (S24 and S25) is
adjusted to the lower limit.
Punching is not performed after punching request is sent, or the
punching request is sent during the punching.
The status of the punch shaft home position sensor (S26) or the rear
punch shaft home position sensor (S22) is not changed after punching
request is sent.
A punching locking signal is detected consistently over the specified
time.
The punch shaft home position sensor (S26) or the rear punch
shaft home position sensor (S22) does not detect that the shaft
is not at its home position at the start of punching or punch
waste full detection.
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 TP25 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
voltage does not fall within the range mentioned, replace the
sensor.
Measure the voltage on TP24 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
voltage does not fall within the range mentioned, replace the
sensor.
Measure the voltage on TP27 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
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): CN2, CN5, CN6)
If the error still occurs after replacing the motor, sensors and
connectors, exchange the hole punch control PC board (HP).
Punch motor (M3) home position detection error: Punch motor
is not rotating or puncher is not shifting normally.
