disconnected from the stapler or the harnesses are open
circuited. Correct if any.
•
Check the harnesses in the stapler are disconnected or open
circuited. Correct if any.
Checking and measures
Measure the voltage on TP23 on the finisher control PC board (FIN).
Then check that the measured voltage is 1V or lower when the sensor
is ON and within the range of 3.3V
±
5% when OFF. If the voltage does not fall within the range
mentioned, replace the staple unit.
Measure the voltage on TP24 on the finisher control PC board (FIN).
Then check that the measured voltage is 1V or lower when the sensor
is ON and within the range of 3.3V
±
5% when OFF. If the voltage does not fall within the range
mentioned, replace the staple unit.
Check if the electrical continuity between the connector terminals is
normal. If electricity is not conducted, replace the connectors. (Finisher
