5.4 Multifeeder Pickup Assembly
5.4.1 Operations
The multifeeder pickup assembly is constructed as shown in F02-504-01.
The multifeeder is a mechanism in which sheets are picked up from a stack placed on the
tray for continuous feeding.
As many as 250 sheets (81.4 g/m 2 paper) may be placed on the tray.
The paper on the tray is detected by the multifeeder paper width sensor (PS4, PS5).
When the Start key is pressed, the stack of sheets is moved up as far as the pickup posi-
tion by the work of the multifeeder lifter motor (M1).
The pickup roller is rotated by the drive of the multifeeder pickup motor (M1) to pick up
paper from the stack.
When the multifeeder pickup roller releasing solenoid (SL5) turns on, the pickup roller
moves away from the surface of the stack of paper; the feeding roller and the separation
roller serve to make sure that only one sheet of paper is moved to the registration roller by
way of the paper thickness detecting roller.
