The transport motor turns on and then the pickup solenoid turns on.
The feed motor turns on and the feed roller rotates. At the same time, through a relay gear, the pickup roller rotates to feed the top sheet of the paper stack.
The reverse roller contains a torque limiter. The friction between the reverse roller and the feed roller exceeds the limit of the torque limiter, and the reverse roller rotates with the feed roller. When two or more sheets of paper are fed, the torque limiter makes the reverse roller rotate to push the lower sheet of paper back to the tray.
When the feed sensor (reflective photosensor) detects paper, the pickup solenoid turns off and the pickup roller lifts away from the paper, to reduce the resistance to paper feed.
