2.2.2 Paper Feed Assembly
PF RAIL
The main paper feed components are the CR Guide Rail, the Grid Roller
Assembly which is attached to the PF Rail, and the Secondary Roller
Assembly which attaches to the back of the CR Guide Rail and faces the Grid
Roller Assembly. The Grid Roller Assembly is made up of three equal lengths
of rollers and their coupling.

The PF Motor is a DC Motor that is controlled by the software servo system,
and the servo receives a pulse from the built-in optical rotary encoder. This
rotary encoder allows for minute paper feeding.
