ERROR CODE AND TROUBLESHOOTING
8 - 203
[CC02] Stack exit roller nip home position detection error
MJ-1032
[CC02] Exit roller nip adjustment motor (M4) abnormality
MJ-1033
[CC20] Saddle communication error
MJ-1106/1108
Faulty cables and connectors Check if the electrical continuity between the connector terminals is
normal. If electricity is not conducted, replace the connectors. (Finisher
control PC board (FIN): CN6, CN16)
Finisher control PC board (FIN)
abnormality
If the error still occurs after replacing the motor, sensor and
connectors, exchange the finisher control PC board (FIN).
Replacement part Measure
Stack exit roller shift motor (M6)
Stack exit roller home position
sensor (S13)
The stack exit roller home position sensor (S13) does not detect
that the exit roller is not at the upper position after the stack exit
roller motor (M6) has been driven in the specified time when the
exit roller is moved down.
The stack exit roller home position sensor (S13) does not detect
that the exit roller is at the upper position after the stack exit
roller shift motor (M6) has been driven in the specified time
when the exit roller is moved up.
Error Timing of detection
Exit roller nip adjustment motor
Exit roller nip home position sensor
The exit roller nip home position sensor (S8) does not become OFF
from ON in the specified time when the status in which the exit roller
nip is large or small is changed to one in which the exit roller or the
middle transport roller is released.
The exit roller nip home position sensor (S8) does not become ON
from OFF in the specified time when the status in which the exit roller
or the middle transport roller is released is changed to one in which the
exit roller nip is large or small.
Probable cause Checking and measures
Exit roller nip adjustment motor (M4)
abnormality
Check if the electrical continuity of the coil is normal. If
electricity is not conducted, replace the motor.
Exit roller nip home position sensor
(S8) abnormality
Measure the voltage on TP31 on the finisher control PC board (FIN).
Then check that the measured voltage is 1V or lower when not
shielded and within the range of 3.3V
5% when shielded. If the voltage
does not fall within the range mentioned, replace the sensor.
Faulty cables and connectors Check if the electrical continuity between the connector terminals is
normal. If electricity is not conducted, replace the connectors. (Finisher
control PC board (FIN): CN2, CN9)
Finisher control PC board (FIN)
abnormality
If the error still occurs after replacing the motor, sensor and
connectors, exchange the finisher control PC board (FIN).
