Details of the paper transportation system

In the paper transportation process, paper is automatically fed by the pick-up roller and transported to the registration roller. The registration roller synchronizes with the transfer belt. The registration roller transports the paper to the transfer roller. During the transfer process, the transfer roller forwards the paper to the fuser rollers. During the fusing process, the fuser rollers transport the fused paper to the exit roller and the exit roller pushes the final paper out of the rear cover assembly.

The paper transportation system consists of the following parts:
