ERROR CODE AND TROUBLESHOOTING
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.
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).
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.
Timing of detection
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.
