Paper Transportation
1 Multi-Sheet Bypass
Feed (MBF) Sensor
Monitors the Front Tray Assembly. The MBF Sensor is ON
when paper is loaded into the Front Tray Assembly.
2 Pick–Up Solenoid Controls the start and stop of the Pick–Up Roll Assembly.
3 Pick–Up Roll Assembly Feeds paper from the Front Tray Assembly. Paper feed begins
when the Pick–Up Solenoid unlatches the Spring Clutch in the
Feed Clutch Assembly, starting the rotation of the transmission
gears in the Drive Assembly. The Pick–Up Roll Assembly cam
converts the rotation to an up and down movement that is used
by the Bottom Plate Assembly to feed paper from the Front
Tray Assembly. After one revolution of the Pick–Up Roll, the
Pick–Up Solenoid latches the Spring Clutch, which stops
transmitting power to the Drive Assembly.
4 Inlet Chute Assembly Has two major components:
Inlet Chute: Made of metal and is electrically grounded, it
discharges any static electricity that accumulates on the paper.
Registration Sensor (4a): Monitors when paper passes
through the Inlet Chute. The sensor is ON when a sheet of
paper is present in the Chute.
5 BTR Assembly The BTR Assembly transfers the toner image from the drum to
the sheet of paper.
6 Transport Chute
Assembly
The Eliminator component of the Transport Chute Assembly
strips the sheet of paper from the drum surface. The Eliminator
is electrically grounded, and helps discharge the static
electricity the paper accumulates during a normal print cycle.
7 Lower Chute Assembly Has two major components:
Take–Away Roll Assembly (7a): Registers the paper with the
toner image on the drum.
Retard Pad Assembly (7b): Prevents the Pick–Up Roll
Assembly from feeding two sheets of paper at a time out of the
Paper Tray.
8 Link Assembly Has two functions:
Safety device: Actuates the LVPS interlock switch when the
Front Transport Assembly is closed. When the Front Cover is
opened, the Link Assembly deactuates the LVPS interlock
switch, removing power from all printer components.
Drum Shutter: Opens the drum shutter on the EP Cartridge
when the Front Cover is closed. When the Front Cover is open,
the Link Assembly closes the drum shutter, protecting the drum
from exposure to light.
