Theory of Operation 2-13
Paper Tray Functional Assemblies
Left- and Right-Side Paper Guide Assemblies The left and right Paper Guides
adjust to fit different paper widths. The guides hold the paper in position in the tray.
Bottom Plate Assembly The Bottom Plate Assembly is pushed up by the Bottom
Lift Spring. The bottom plate is released by unlocking the Bottom Lock Lever and
Stopper Gear. When the Bottom Plate Assembly is pushed up, the supplied paper
contacts the Nudger Roller.
Bottom Lock Lever and Gear Stopper These are at the rear of the tray (i.e., the
front end in the direction of travel of paper). How these components work is explained
in “Paper Lift Mechanism” on page 2-15.
Extension Lock The 150-Sheet Tray extends to accommodate different paper
lengths. The Extension Lock holds the extension in position.
