Printing from Tray 2 When the formatter PCA sends the /PRNT (print signal) to the printer, the CPU turns the Tray 2 pickup solenoid (SL306) on about 0.15 seconds after the main motor (M1) starts rotating, then turns on the feed roller clutch (CL406). The main motor rotates the Tray 2 pickup roller and feed rollers. The Tray 2 pickup roller rotates a full circle with the Tray 2 pickup solenoid (SL306) and picks up one sheet of paper from the tray. The paper is fed into the printer as the feed rollers rotate. The paper passes through the registration roller paper sensor (PS403) and stops at the registration roller that is not turning, momentarily stopping the leading edge of the paper and correcting its skew. The CPU turns the feed roller clutch (CL406) off within a specified time and stops the feed roller rotation. The CPU turns the registration roller clutch (CL405) and feed roller clutch (CL406) on about 1.3 seconds after the scanner becomes ready and feeds the paper through the transfer area, feed belt, fuser, and delivery unit and outputs it to the top output bin.
