Laser Toner Cartridge Schematic
Your laser toner printer uses static electricity to transfer toner powder from a toner cartridge to your printed page. Objects with opposite static electricity fields are attracted to each other just like metal shavings are
attracted to a magnet. The key to a laser toner cartridge is a revolving cylindrical drum which is in the toner cartridge. This drum is coated with a highly photoconductive material that can be charged by a light beam. As the drum rotates, the printer's laser
beam 'draws' the letters and images on the drum surface creating a negative charge on the drum in the exact image of what is to be printed.
Next, the toner cartridge coats the drum with positively charged toner powder, which is also inside of the toner cartridge. Since it has a positive charge, the toner clings to the negative charged areas of the drum, but not to the rest of the drum.
With the powder in place on the drum, the paper is rolled against the cylindrical drum, which also happens inside of the cartridge. Before the paper rolls under the drum, it is given a negative charge by a negatively charged roller. This charge is
stronger than the negative charge of the electrostatic image, so the paper can pull the toner powder away from the drum.
After the toner powder is transferred to the paper, a wiper (similar to a windshield wiper) wipes any remaining toner away from the drum so the drum is perfectly clean for the nest page.
Finally, the printer passes the paper through the fuser, a pair of heated rollers, which is not a part of the cartridge, but part of the printer itself. As the paper passes through these rollers, the loose toner powder melts, fusing with the fibers in the
paper. The fuser rolls the paper to the output tray, and you have your finished page. The fuser also heats up the paper itself, of course, which is why pages are always hot when they come out of a laser printer or photocopier.
