ERROR CODE AND TROUBLESHOOTING
Checking and measures
Measure the voltage on pin CN16.12 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.
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)
If the error still occurs after replacing the motor, sensor and
connectors, exchange the finisher control PC board (FIN).
An encoder pulse interruption error or rotation abnormality
occurs in the saddle stitch finisher folding motor.
• Sensor check (S34)
• Connector check
• Harness check
Harness check
• Connector check (CN11, CN14)
• Board check
Timing of detection
The turning OFF of the stacker home position sensor (S21) is
not detected in the specified time when the stacker is moved
from a point where this sensor is turned ON to one point where
this sensor is turned OFF.
The turning ON of the stacker home position sensor (S21) is not
detected in the specified time when the stacker is moved from a
point where this sensor is turned OFF to one point where this
sensor is turned ON.
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 pin CN16.15 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.
