You must memorize the 6 steps of laser printing. They are as follows, in the correct order:
1. cleaning (excess toner is scraped from the photoelectric drum)
2. conditioning(a uniform -600 volt charge is placed on the photoelectric drum by the primary corona)
3. writing(laser diodes write an invisible electric image on the photoelectric drum by causing the drum surface to be less negative wherever the laser beam hits)
4. developing(this is where the transfer roller places the toner on the drum. The toner sticks to the areas that have had the electric charge lessened due to the laser beam)
5. transfer(the secondary corona uses a positive charge to attract the toner from the drum to the paper)
6. fusing(the toner is then melted into the paper)
