Laser Printer

Laser Printers uileláithreach now in the office environment and copying. Developed the first laser printers from Xerox in 1971 and in 1977 was introduced on the market. The speed of laser printing Crisp was soon on popular option for many consumers, although the internal operation remained mysterious for many of the printer. Because the name, some consumers believe that laser printers use a laser-active way on paper. Indeed, the actual laser printers use static electricity to print, although Lasers role in the printing process.

Start Laser print job data from a computer and delivered through a central controller, a small computer in the printer to manage the printer. There are many laser controller that can handle multiple tasks at the same time enqueuing them, and then print. This makes the ability to handle multiple data laser is very popular. After the controller has to decide what printing process begins.

The interior of the drum is that laser printers are electrical charge. Besides Corona drum roller, which can negatively or positively charged the battery as needed, units and toner. Most laser printers, the drum begins to make a positive, although this process can work even in otherwise. Manipulate the controller with a small laser to "write on the drum with a negative charge, creating electrostatic image.

The drum is then rolled through the toner, which is positive, so it clings to the charged areas of the negative charge on the printer drum. The printer feeds a piece of paper, as even stronger negative charge on the Corona bank before being applied to the drum over. The image on the electrostatic drum transfer paper to a release from detention to prevent the drum. Then it is encouraging to foirneis the toner are heated and bound to the fibers in the paper.

Meanwhile the drum along a gas discharge lamp, a full disclosure on the surface of the drum and remove the electrostatic image. The Corona wire transfer the other positive charge and the printer is ready for the next page or use.

Color Laser Printers that work. Most printers blue, red, yellow and black ink also can be placed together form any color. Some printers gradually the ink on the drum so that the printed image with a passage from the paper, but others circulate the paper several times to a series of progressive implementation of color. Large format color printer for hours on drum and toner assembly for each color, the paper separate drum.
