Cover Open

Opening the stacker cover turns off the microswitch on the high-voltage power supply board to
suspend +5 V supply to the high voltage power supply. This results in the stop of all high-voltage
outputs. At the same time, the CVOPN signal is issued to notify the main control board of the
switch status and cover open processing is executed.
