The seven steps used by a laser printer to print a page are :
1) Processing, this is where he computer sends the data to the printer.
2) Charging, where the wire (primary corona) negatively charges the
photoconductive drum.
3) Exposing, where the laser scans the image to the drum. Anywhere the
laser touches the drum causes the electrical charge to drain off.
4) Developing, where negatively charged toner particles are allowed to
attach to the painted area of the drum; since the negative charge has
been drained off these areas
5) Transferring, where the transfer corona wire charges the paper with a
positive charge from behind. The negatively charged toner jumps to the
positive paper, according to the image on the drum. A Static Charge
eliminator then removes any residual charge.
6) Fusing, where the toner particles attached to the paper are fused or
melted to the paper, because of the heated drum.
7) Cleaning, where the drum is cleaned of excessive toner and electrical
charges.
