Printing from tray 2When the dc controller PCA receives print command, the main motor (M101) and scanner motorstart their rotation. When the main motor reaches its prescribed speed, the feed-roller clutch (CL101)and tray 2 pickup solenoid (SL101) are activated. (The main motor rotation drives the tray 2 pickuproller, tray 2 feed roller, tray 2 separation roller, and paper-feed rollers.)The pickup solenoid activates the tray 2 pickup roller, which rotates once and picks up the media inthe tray. The separation roller prevents additional sheets from feeding with the first sheet, and themedia is fed to the pre-feed sensor (PS102).When the sheet reaches the registration assembly, its skew is corrected. The sheet then passesthrough the transfer, separation, and fusing stages, and through the delivery unit, and then isdelivered to the output bin.Figure 5-16 Tray 2 timingPickup, feed, and delivery system 107
