Free run test mode starts when the SW100 on the main board is pressed,
and stops when the SW101 is pressed.
Operation:
1. Motor Free Run
The motors of the finisher are energized in the following order:
Transport drive motor
Shift motor
The PCB checks the speed of the transport drive, exit and stack feed
motors, and mechanical lock of the other motors.
2. Staple Free Run
The finisher works as if 5 sets of 5 LT papers are being stapled and
delivered. The machine is then initialized and repeats the same operation.
3. Shift Free Run
The finisher works as if 10 sets of 5 LT papers are being sorted. The shift
tray is lowered for each of the 2 sets and then returns to its home position
to repeat the same operation.
