Pick-Up From The Cassette - Canon GP215 Service Manual

B. Pick-Up from the Cassette
1. Pick-Up Operation
The copy paper inside the cassette is held up by the lifter so that it is in contact with the pick-up roller
during pick-up.
The pick-up roller is driven by the cassette pick-up motor (M4) and is lowered to reach copy paper at
time of pick-up.
The pick-up roller is lowered by the movement of a cam operated by the drive of the main motor (M1)
switched by the pick-up roller down solenoid (SL2).
The feeding roller and the separation roller make sure that only one sheet of copy paper is fed; the copy
paper is moved to the feeding assembly and then to the registration roller by the vertical path roller 1/2.
The drive of the vertical path roller and the pre-registration roller is from the main motor (M1) switched
by turning ON and OFF the vertical path roller clutch (CL3).
The drive of the registration roller is from the main motor (M1) coming by way of the registration roller
clutch (CL1).
Figure 3-603 shows the arrangement of the electrical parts and the concept of the drive mechanism,
and Table 3-603 shows the sensors and sensor signals.
