When the left and right upper output stackers are removed:
The paper exit selection switch [1] under the left output stacker comes up and opens the
switch.
This activates the [2] paper junction gate solenoid which opens the paper junction gate [3].
The open junction gate guides paper out the back of the machine.
With both the upper output stackers removed, the lever [4] must be lowered so the original
can pass over it. (With both left and right output stackers removed, the original must exit to
the rear.)
