HP M750 series

1. The DC controller reverses the fuser motor to rotate the fuser pressure release cam.
2. The pressure roller is pressurized or depressurized depending on the position of the cam.
The DC controller determines a fuser pressure-release mechanism abnormality and notifies the formatter
when it does not sense the fuser pressure-release sensor for a specified period from when it reverses the
fuser motor.
