2.2.2 Paper Feed Mechanism
The main components of the paper feed mechanism are described below.
PAPER FEED MOTOR AND ROLLERS
When paper is loaded, it’s held against the Paper Feed Roller by the Paper
Pressure Rollers. Raising the Paper Release Lever (see
Figure 2-10
) moves
the Paper Pressure Rollers away from the Paper Feed Roller, and releases
any loaded paper. The Paper Feed Roller Assembly is made up of three equal
lengths of rollers and their coupling.
The PF Motor uses a DC motor, which has a built-in optical rotary encoder. The
encoder sends signals to the software servo system, which regulates the
speed of the motor. Motion is transferred through a timing belt to the Speed-
Reduction Gear, which improves the accuracy of paper feeding.
