Feed Clutch Assembly
Consists of a gear and a electric clutch located on the end of the Feeder Assembly shaft. This
clutch controls the transmission of the drive power from Gear 3 through the Turn Clutch
Assembly to the Roll Assembly of the Feeder Assembly by turning on and off the Feed clutch.
When this clutch is activated, the drive power is transmitted to the Feeder Assembly.
Feeder Assembly
Consists of the Nudger Support Assembly, Shaft Feed and Roll Assembly. The task of this
Assembly is to pick the paper from the Paper Tray Assembly and feed it to the Turn Roll Assem-
bly. To ensure this task, the Nudger Support Assembly acts as the actuator for the Stack Height
Sensor Control by swivelling itself up and down synchronizing the height of the stacked paper.
Turn Roll Assembly
This Assembly feeds the paper to the Standard Feeder Assembly path. The mechanical activity
is same as the Turn Clutch Assembly.
Feeder PWB
Connective interface between the Sensors, Clutches and Motor, and the Size Option PWB.
This PWB also monitors the No Paper Sensor which detects the out of paper condition of the
Paper Tray.
Size Option PWB
Controls the Option Feeder Assembly, the interface function between the Size Option PWBs,
the Feeder PWB, and the Print Engine Controller PWB.
Figure 4 Major Components of the Option Feeder Assembly
No Paper Sensor
Detects the out of paper of the Paper Tray Assembly.
No Paper Actuator
Actuates the No Paper Sensor. When out of paper, this actuator will swivel down and shield the
No Paper Sensor.
Low Paper Sensor
Detects the state of low paper of the Paper Tray Assembly. Low paper detect is at approxi-
mately 50 +/- 30 sheets of paper.
Stack Height Sensor
Detects the state of the paper level (the position of the top sheet of paper). This sensor is actu-
ated by the Nudger Support Assembly.
Size Switch
Mounted on the Feeder PWB and detects when the Paper Tray Assembly is out of paper.
