Media tray assembly It is necessary to adjust the rear and the end guide in the media tray assembly to match the media size. Rear media guide The rear media guide can be adjusted to different media sizes by moving it to the front or rear. The guide comes into contact with the rear edge of the media and holds it in position. Bottom plate The force pushing up the bottom plate is transmitted by the driving force of the motor on the media feed unit assembly. The bottom plate is pushed up by the rotation of the lift up shaft, which causes the supplied media to come in contact with the pick roll. Diagnostic aids 3-117
