2000-Sheet Feeder Drive and Electrical
• Feed Motor
This motor, one on each Feeder, is activated by the Level Sensor to feed paper and to lift
the Bottom Plate. When feeding paper, it rotates forward to drive the Nudger Roller. When
lifting the Bottom Plate, it rotates in reverse to drive the tray gears to turn the Lift Shaft.
• Door Interlock Switch
The Door C Interlock Switch detects whether Door C is open or closed.
• Take Away Clutch
The Take Away Clutch transmits Take Away Motor force to the gear set driving the Take
Away Roller.
• Feeder Board
The Feeder Board controls media feeding on command from the MCU Board and reports
sensor/switch information.
• Take Away Motor
The rotating force of the Tray 4-5 Take Away Motor is transmitted through the gears to the
Take Away Roller as shown in.

Principles of Operation

Mailbox

Mailbox
The Mailbox provides 4, individually assigned 100-sheet output trays. This allows for job colla-
tion or specific output tray assignment. The Mailbox Control Board communicates with the
MCU Board to receive instructions to activate the IOT exit gate using the Lower Diverter Drive
Assembly, cam follower, and exit gate actuator to divert media into the Mailbox and subse-
quently into one of the four output trays,
Figure 1 Mailbox output trays
NOTE: Output trays are identified as Bins 1 through 4 with 4 being the uppermost tray.
Media is detected entering the Mailbox by the Mailbox Entrance Sensor. As media enters, the
Diverter Drive Assemblies move a series of diverter gates to direct the media to the requested
output tray. Position of each diverter is monitored by the Diverter Home Position Sensor
located on each of two Diverter Diver Assemblies (upper/lower). Two sensors monitor the
amount of media in each tray to signal empty and full conditions.
Mailbox Sensors
These sensors monitor Mailbox status and media location,
