C-320/C-320C and C-380/C-380C Technical Service Manual

Reassemble the shredder and test the basic shredder functions,

including:

Make sure the Ready Light (green) shines brightly when the

power is on. This indicates the correct LED alignment between
the PC board and the cover.

Open the cabinet door to make sure the Door Ajar light is

working.

Open the cabinet door and cover the bin full sensors with a

piece of masking or non-clear tape. Close the door, turn on
the shredder, and wait about 8 seconds for the bin full sensor
to turn on. When the bin full sensor light turns on, remove the

tape from the sensors.

Press the Manual Forward button to make sure it is working.

Place a sheet of paper in the paper entry slot to make sure the

auto-start feature is working.

Press and hold the Reverse button to make sure it is working.
