Pressure roller pressurization and depressurization control
To prevent excessive wear on the pressure roller and help with jam-clearing procedures, the pressure roller
pressurizes only during printing and standby. The DC controller reverses the fuser motor. The fuser motor
rotates the fuser pressure-release cam.
