5-38 Functional Information
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.
