Theory of Operation
■ Tray 3 Bottom Plate
The Bottom Plate is locked to the bottom side when the Tray is pulled out
from the paper feeder, and unlocked when the Tray is installed into the
paper feeder. The Bottom Plate pushes the paper against the Feed Roll
using a spring tension.
a. When the tray is inserted into the Sheet Feeder, the Actuator is
pushed toward the front by the Left Guide, which pushes the Stopper.
b. The Stopper unlocks the Bottom Lock Oneway Gear.
c. When the tray is pushed until it stops, the Bottom Lock Lever is
pressed down by the Support Nudger in the Feeder.
d. The Bottom Lock Lever actuates the Bottom Lock Lever Gear, which
pushes the Bottom Rack Lock toward the rear.
e. The gear on the Bottom Rack Lock is disengaged from the Bottom
Lock Oneway Gear, which allows the Bottom Plate to raise up by the
Bottom Up Springs.
