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. The now-negatively charged areas of the drum represents the image or text that is to be printed.

The printer's job is to convert this electronic data back into words and pictures: in effect, to turn electricity into ink. With an inkjet printer , it's easy to see how that happens: ink guns, operated electrically, fire precise streams of ink at the page. With a laser printer, things are slightly more complex.

We have just talked about how a laser printer works using heat, static electricity, toner, and moving parts to create your desired print. However, numerous other moving parts and components work harmoniously inside a laser printer to create your final document or photo.

To begin the laser printer process, the document is broken down into digital data and sent from the respective computer to the printer. In a feat of binary wizardry, printers reassemble this computer data into a printed image. Laser printers will capture the data and process the digital document. Step 2: Cleaning

The primary principle at work in a laser printer is static electricity, the same energy that makes clothes in the dryer stick together or a lightning bolt travel from a thundercloud to the ground. Static electricity is simply an electrical charge built up on an insulated object, such as a balloon or your body.

The only scientific principle you need to remember, in order to understand the working of a laser printer is ‘ Like charges repel each other and unlike charges attract each other ‘. Let us understand the process of monochrome laser printing stepwise in the following lines.

LASER Principles of working of a laser. In lasers, photons are interacted in three ways with the atoms: Absorption of radiation; Spontaneous emission; Stimulated emission; Absorption of radiation

Introduction Printers are classified into Impact and non impact printers. LASER stands for Light Amplification by Stimulated Emission of Radiation. Laser printers uses electrostatic printing process. Laser printers are used to produce high quality images and graphics. It is a type of printer that utilizes a laser beam to produce an image on drum. It uses a non-impact (keys don't strike the paper), photocopier technology.

The laser of a laser printer is a stationary object. The beam is directed and reflected by the mirror and a variety of lenses. Much like an inkjet printer drops tiny dots of ink in precise locations in order to make up a printed page, the laser pulses across the surface emitting a pulse of light for every dot where there part of the image will be revealed and not pulsing where there is no image to be transferred.

How Laser Printers Work . The printers laser beams your print onto a metal cylinder called a drum. Using static electricity, the drum attracts powdered toner from its cartridge to the drum. The drum rolls the toner onto the paper in the form of your print. The toner is melted onto the paper by heat from a fuser as it passes underneath.
