CHAPTER 7 PICK-UP/FEEDING SYSTEM

B. Sequence of Operations (pick-up from the cassette)

1. Pick-Up Operation

The paper inside the cassette is held up by the lifter, and it is in contact with the pick-up roller

at time of pick-up.

The pick-up roller is driven by the cassette pick-up motor (M5), but is moved down by means

of a cam operated by the drive of the main motor (M1) switched by the pick-up roller down

solenoid (SL1).

The feeding roller and the separation roller make sure that only one sheet of paper is moved to

the feeding path; the paper is then moved as far as the registration roller by the No. 2 registration

roller and the vertical path roller.

The drive of the vertical path roller and the No. 2 registration roller is switched by turning on

and off the vertical path roller clutch (CL3).

The drive of the registration roller comes from the main motor (M1) by way of the registration

roller clutch (CL1). Table 7-103 and Figure 7-103 show the loads in the cassette pick-up assembly

and a conceptual diagram of the electrical parts.
