Paper Path
The paper pickup and feed system is responsible for picking paper from the input paper tray,
delivering it to the image formation system at precisely the right time, feeding it to the fusing
station, and delivering it to the output tray. Figure 5-13 illustrates the ~ 33440~ 33449 paper
path. The -sette-feed paper path begins when the Machine Control Sys@m (DC Controller
PCA), &er receiving a print command, starts the Main Drive Motor. Approximately NO seconds
later, the Paper Pickup Solenoid is enabled md the Paper Pickup Ro~er makes one rotation and
feeds paper to the ReQstration RoUers. Since the Registration Rollers are not turning at this time,
the front edge of the paper bows (see Figure 5-14).
