Initial Actions
Ensure that the electricity to the machine is switched off while performing tasks that do
not need electricity. Refer to GP 14. Disconnect the power cord. Electricity can cause
death or injury. Moving parts can cause injury.
Do not run code 11-050 without two sheets of paper in the stapler jaws. Running this code with-
out the paper in position can cause damage to the machine.
If stapling has failed, perform the following:
• Check that the staple head unit is correctly installed.
• Check that the staple cartridge has staples in it and is correctly installed in the staple
head.
• Check that the leading staples in the staple head have been primed.
• Check that the sheets of staples in the cartridge are feeding one at a time. If staples
sheets overlap, they will jam in the cartridge. If necessary, install a new staple cartridge,

Procedure
NOTE: The sensors Q11-364, Q11-363, Q11-360 and Q11-362 are integral to the staple head
unit and although they can be checked they are not separately spared.
Figure 1 and Figure 2 show the locations of the components.
Enter dC330, code 11-053 to run the stapler unit motor, MOT 11-053 and send it to the inboard
end of its travel. The motor runs.
