3. OPERATION AND TIMING
3. Multifeeder Pick-Up Assembly
a. Operation
The multifeeder pick-up assembly is constructed as shown in Figure 3-608.
The multifeeder is a mechanism that picks up paper from a stack on its tray for continuous feeding.
As many as 250 sheets of paper (80 g/m
The paper on the tray is detected by the multifeeder paper sensors (PS4, PS5).
When the Start key is pressed, the stack of paper is raised to the pick-up position by the multifeeder lifter
motor (M1).
The pick-up roller is rotated by the drive of the pick-up motor (M10) for pick-up of paper.
Then, the multifeeder pick-up roller releasing solenoid (SL5) turns on, moving the pick-up roller away
from the surface of the paper.
A single sheet of paper is moved by the feeding roller and the separation roller to the registration roller by
way of the paper thickness detecting roller.
The CLC1000 checks the thickness of paper when picking it up from the multifeeder, thereby identifying
it as being plain or thick. (For transparencies, see "4. Picking Up Transparencies.")
