2.7 Cover Open
When the stacker cover is opened, the cover open microswitch on the power/sensor board is
turned off to cut +5V supply to the high voltage power supply circuit. This results in the interruption
of all high-voltage outputs. At the same time, the CVOPN signal is sent to the control board to
notify that the microswitch is off, and the control board carries out the cover open process.
