HP — Printing from Tray 2

Printing from Tray 2 When the Formatter inputs the /PRNT signal to the printer, the Main Motor (M1) starts rotation. When the Main Motor reaches its prescribed speed, the Feed Roller Clutch (CL101) and Tray 2 Pickup Solenoid (SL 101 or SL 103) are turned on. (The Tray 2 Pickup Roller, Tray 2 Feed Roller, Separation Roller, and Feed Rollers are driven by the Main Motor rotation.) The Tray 2 Pickup Roller, driven by the Pickup Solenoid, rotates once and picks up the paper in the tray. The unnecessary sheets are removed by the Separation Roller and the paper is fed to the pre-feed sensor (PS102). The CPU monitors the condition of the PS102 for a prescribed period of time.

If PS102 does not detect paper within that time, the CPU resumes feeding the paper, maintaining the appropriate between-page distance for continuous printing. The paper then reaches the Registration Arm, where its skew is corrected. Then it goes through transfer, separation, and fusing stages, passes through the delivery unit, and is delivered to the tray.
