Working principle of canon g3800 paper feeder

The paper feeding device of printer includes three parts: media separator, media stopper and paper feeding mechanism. Paper separation depends on the joint action of paper rollers and separation pads, and its principle is that the friction between papers, between paper rollers and between papers and separation pads is different. When the paper feeding mechanism drives the paper roll to feed paper, the paper enters. The paper stop mechanism is used to prevent the paper stack from being misplaced or dislocated when it is put in. Because each user's hand strength is different, it will increase the chance of picking more. In fact, there is more than one separation pad, and there will be a group of separation pads to ensure that only one piece of paper can be fed at a time. Usually, in this case, a compromise scheme will be adopted to ensure that neither multiple sheets of paper are fed at one time nor paper is fed. Hehe, doesn't it sound complicated?
