Cover Open
When the stacker cover is opened, the cover open microswitch on the power supply/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 main control board to notify that
the microswitch is off, and the main control board carries out the cover open process.
