2.1 Mechanical Drive
2.1.1 Overview
Mechanical Drive is a term that is used to describe both the rotation of
the printer motors and the action of the gear clusters and clutches that
are used to transmit and control motor rotation to the various
components throughout the printer. The primary purpose of Mechanical
Drive within the printer base is to drive a sheet of paper out of a
selected paper tray, through the printer and into an output tray. The
ROS Motor is not considered part of Mechanical Drive. The Main Drive
Motor turns the Main Drive Assembly gears. The Drive Assembly
provides drive to the Feed Clutches, the Registration Clutch, the Fuser,
the Drum and BTR, and the Exit Clutches. Lift Up Motors supply drive to
each paper tray; raising the Bottom Plate of each tray so the paper
stack contacts the Feed Rolls. The Offset Motor provides drive to the
Offset Rolls.
