Step 1 - ID Sensor shutter-
Please note the following when detaching the Bk drum unit because the ID sensor shutter may come off depending on the
way to detach the Bk drum unit (Note 1). In a rare case, it causes the color registration drift if the main machine continues
drive while the ID sensor shutter comes off.
Note: When detaching the Bk drum unit, please hold the both sides of that unit, and pull it frontward along the guide rails
inside the machine.

* In the normal operation, the ID sensor shutter opens by sliding
rightward when closing the top tray, and it closes by sliding
leftward when opening the top tray. (Above is the state when
opening the top tray.)
