Then, the deck main motor (M1D) goes ON, and the rotation of the pickup roller moves the paper into the machine. The pickup/feeding roller and the separation roller make sure that no more than a single sheet of paper is picked up. After the deck pickup sensor (PS6D) has detected the presence of paper, the pickup roller leaves the surface of paper when the deck pickup roller releasing solenoid (SL1D) goes ON. When paper is fed, the deck feed roller rotates to move the paper to the registration roller of the host machine, where the paper is looped so that it does not skew. The registration roller is controlled so that the image on the photosensitive drum and the leading edge of the paper will match.
