Quick Answer: How Does A Laser Printer Work?

How a laser printer works. They work by using a heated wire to positively charge a drum, which is then passed over by a laser that reverses the charge in the areas that it hits. A toner roller is passed over the drum, and toner particles stick to the negatively charged areas.

How does a laser printer work simple explanation?

Laser printers are similar to photocopiers In a photocopier, a bright light is used to make an exact copy of a printed page. The electronic data from your computer is used to control a laser beam—and it’s the laser that gets the ink on the page, using static electricity in a similar way to a photocopier.

How does a laser printer operate?

Like a photocopier, laser printers read the electronic data from your computer and beam this information onto a drum inside the printer, which builds up a pattern of static electricity. This attracts a dry powder called toner onto the paper which is then fused using heated rollers.

How do laser printers work without ink?

Laser printers use toner powder instead of dye or pigment-based ink. Laser printers produce electrostatically charged dots on a light-sensitive drum which attracts toner powder. The toner is transferred to the paper and fixed by a heating process.
