Shutter Mechanism
The laser optics housing unit has a shutter. As a result, toner and other dust do not fall on the glass of the laser optics housing. The shutter motor [A] moves the shutter [B] in the direction of the arrow with the cam [C] (to open: black arrow direction, to close: white arrow direction). First, the actuator [D] stays at the shutter closed sensor [E]. The shutter motor opens the shutter and the actuator moves to the shutter open sensor position [F] after the polygon motor has turned on. Finally, the shutter motor closes the shutter and the actuator moves back to the shutter closed sensor position [E] after the polygon motor has turned off.
⇒ One of SC290 to 296 occurs if the output of the shutter open [F] or closed sensor [E] does not change after the shutter motor turned on.
