012-221A, 012-223A Front Tamper Home Sensor Fail RAP
BSD-ON:BSD 12.4 Integrated Office Finisher Tamping and Offset
Initial Actions
NOTE: Ensure the correct RAP is performed, refer to the
Home Sensor Fail Entry RAP.
WARNING
Ensure that the electricity to the machine is switched off while performing tasks that do
not need electricity. Refer to GP 10. Disconnect the power cord. Electricity can cause
death or injury. Moving parts can cause injury.
• Check the front tamper home sensor,
foreign object and that the actuator is not broken.
• Switch off, then switch on the machine,
Procedure
Check the front tamper for any foreign object, deformation and binding that prevents it from
moving. The front tamper is good.
Y N
Repair the deformation or remove the foreign object(s) and the binding. Install new com-
ponents as necessary, PL 12.26.
Check the drive mechanism to the front tamper for a deformed or broken part and not-seated
gears. The drive mechanism is good.
Y N
Repair the front tamper mechanism. Install new components as necessary,
Enter dC330 code 012-220. Manually move the front tamper to actuate the front tamper home
sensor. The display changes.
Y N
Check the connections of P/J8700 and P/J8724. The connectors are good.
