The pressure release mechanism helps the user to remove paper jams from the fusing unit more easily.
The pressure lever [C] is released by the paper exit/pressure release motor [A], and the pressure roller [D] separates from the fusing sleeve.
The pressure roller HP sensor [E] detects the encoder [B], and determines the position of the pressure roller.
After replacing the pressure roller, if the sensor does not detect the encoder 3 times continuously after a job is completed, SC569-00 (Paper Exit/ Pressure Release Motor Error Detection) is generated.
