250-sheet/550-sheet tray assembly
Media size sensing
The media size set for the media tray assembly is set by positioning the right media guide, unlocking the slider
lock, and sliding the rear paper guide. The rear paper guide triggers the movement of the auto size sensing
finger, which then sets the switches of the controller card board. The combination of ON/OFF position of the
three switches provides information of the media sizes to the engine.
