The actuator of the paper height sensor performs two functions:

  • First, it rises and actuates the Paper Height Sensor (TE) to detect tray full.

  • Second, if the actuator rises far enough through the gap of the paper height sensor (TE) it will trip the arm of the shift tray upper limit switch. This is a fail-safe device to switch the finisher off if one or more other sensors fail.
