Printing from tray 2 When the DC controller PCA receives print command, the main motor (M101) and scanner motor start rotation. When the main motor reaches its prescribed speed, the feed roller clutch (CL101) and tray 2 pickup solenoid (SL101) are activated. (The tray 2 pickup roller, tray 2 feed roller, tray 2 separation roller, and paper feed rollers are driven by the main motor rotation.) The tray 2 pickup roller, activated by the pickup solenoid, rotates once and picks up the media in the tray. The unnecessary sheets are removed by the separation roller and the media is fed to the pre-feed sensor (PS102). The sheet then reaches the registration assembly, where its skew is corrected. Then it goes through transfer, separation, and fusing stages; passes through the delivery unit; and is delivered to the output bin. Figure 18.
