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 uses a DC Motor and is controlled by the software servo system
which receives a pulse from the built-in optical rotary encoder. The PF Roller
torque is transferred through the PF Roller shaft edge (left frame), and turns
the PF motor pinion gear and timing belt.
