Explanation
The laser scanner assembly (also called the laser imaging unit) contains the laser diode and mirrors that scan the laser beam across the photosensitive drum. The laser selectively discharges areas of the drum to form a latent electrostatic image, which then attracts oppositely charged toner particles. The fusing assembly melts the toner onto the paper. The registration assembly controls paper timing and alignment. The transfer roller transfers the toner image from the drum to the paper - none of these create the image on the drum.
