HP Enterprise CP5525 manual Pressure roller pressurization and depressurization control

Pressure roller pressurization and depressurization control

The product releases the pressure roller from the fuser sleeve, except during printing, to prevent deforming the fuser sleeve and the pressure roller and to facilitate the jam-clearing procedure.

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.
