Canon CP660 Service Manual page 173

r When the paper on the cassette holding plate comes into contact with the pick-up
roller, the pick-up roller shaft is pushed up, freeing the fixing arm so that the lift-up
releasing arm will move up the pick-up roller shaft to wait position by the force of a
spring. At the same time, the pick-up roller shaft fixing arm and the lift-up releasing
arm are driven to fix the lift-up cam in place, thereby stopping the lift-up arm and
ending the lift-up operation.
