Feeding from Bypass Tray
When sheet feeding from the Bypass Tray starts, the Feed Roller rotates, driven by the Paper Transport
Motor and controlled by the Bypass Tray Feed Solenoid, to feed the sheet to the position where it is
nipped between the Feed Roller and the Retard Roller.
As the Feed Roller rotates, the Left and Right Bypass Tray Cams also rotate to lift the Bottom Plate
Assembly via the Left and Right Bypass Tray Arms to the position for sheet feeding.
Normally, when only one sheet is fed, both the Feed Roller and Retard Roller rotate to allow the sheet to
pass. However, when two sheets are fed concurrently, only the Feed Roller rotates and the Retard Roller
is locked thereby allowing the upper sheet to pass by being separated from the lower sheet that is
stopped by the friction with the Retard Roller at rest.
The Retard Roller is being pushed toward the Feed Roller by spring pressure, and controlled by the
torque limiter (Friction Clutch Assembly) with which it is coupled.
