The laser is a very useful device in that it uses a concentrated beam of light to write text and draw on paper, as ordered by a computer program. This is much like a Xerox machine, instead of only on paper, it translates into machine code readable text and images.

Principles of lasers, working in accordance with the principles of static electricity. Static electricity can act as an electrical charge built by an object definedblocks. Elements with atoms of opposite charge are attracted to each other and be together. This is what makes the plastic pellets that make up the toner powder cling to the paper passes through rollers laser printer. Everyone has a field of opposite charge, which allows them to be together.

The most important element in laser, which corresponds to a photocopier, the photoreceptor, which is usually a rotating cylinder (often called the heap. This is a drummade of photosensitive material to light emitted photons. At the risk of discussion drum with an electric current is called a corona wire or a roller inside the machine with an electric current running through the country. As the drum turns in the processing of a task, the lights of a laser beam on the surface to meet the specific element. Allows the lawyer to repeat the talk in the form of a model of electric charges. This type of image called electrostacticpicture. Electrostatic images can be a negative image on a background of positive charge, or vice versa.

After the model is formed, color laser printer coats the drum with the toner is positively charged. And he's too negative ions on the surface of the drum, but not to other areas. The areas to be collected, the toner observe the image as a glue, so you can make on paper. In essence, what you get is an image of static electricity, which is written intoner dust on the rotation of the drum.

Once the model is determined the drum rolls on a sheet of paper, which also negatively charged. This charge is more negative than the negative charge electrostatic image on the lists, so the paper to draw the image of the roles and on paper. The document was immediately fired after he raised the image so that there are too many on the rotating drum.

The printer controller is the laser printer main boardcomputer. It speaks to the host computer (eg personal computer) via a communications port, a parallel port or USB. At the beginning of the laser printing process talk with the host computer to see how they will share data. The driver may be necessary to initiate the host computer and stops often the information received to be treated.

Finally, the printer until the paper through the merger, which pushes them forward in a series of heatedrolls. The toner powder is made of polymers loaded with plastic pellets to be melted and sealed paper to create an image. As the paper passes through the rollers, the loose toner powder melts and becomes one with the fibers of the paper. Fuser paper supplies for outgoing mail, and you've finished your color page printed. The fact that a merger of heating to 200 degrees inside the car is responsible for the reason that the paper is not always so warm whenis generated from a color laser printer or copier.
