Disabling the Stapler
There are three fences in the stapler path. The stapler must not
staple these fences.
To disable the stapler, an actuator in the stapler is pushed into the
stapler safety sensor when the stapler is at one of these fences.
When the machine detects this actuator, the stapler will not
operate.
