What is a laser printer?

Answer 1

A high speed printing device that primarily uses a laser and static electricity for attaching toner to paper. I believe it should really be called the static electricity printer! You see; the primary principle at work in this machine is static electricity. The laser inside the printer never really touches the paper.

The LASER printer really has four basic parts that are most important.

1. The laser Unit (with mirror)

2. The Toner Hopper

3. The Drum Assembly (with 3 additional parts)

4. And the Fuser assembly.

How a laser printer is working:

1. Whenever the printer gets its information, the printers' circuit board then takes that information and converts it into a code. Like Morse Code.

2. The laser prints it to a negative (statically) charged rotating drum.

3. when the laser pulses light on the drum it creates a small DOT of neutral electricity.

4. the drum or (toner hopper) charges the toner powder to a negative charge as well.

5. when the toner is pushed through the drum the toner is sucked into the Neutral spaces left by the laser. Creating an image.

6. paper is Positively charged. and pushed through the drum. The toner is statically bonded to the paper. Like a magnet, it sticks together.

7. the fuser assembly heats up 300+ degrees and fuses the toner to the paper.

Different from inkjet printers using ink, laser printers use toner as printing materials.

Ink cartridges are usually cheaper than toner cartridges. However, toner cartridge has the lower cost per page than inkjet does.
