What is the LED printer?

Using LED (LED) Emitting LEDs is a LED printer piece of computer hardware that uses the method without impacting images and text on paper. Like the laser printer to achieve this, the LED toner and heat printer uses. However, LED printers have fewer moving parts than laser printers and theoretically they should be more reliable over time.

The page is sent to the LED printer processor that controls the LED series. The LEDs flash the image of the page, line along the line, on a photo -sensitive drum that captures an electric charge where it is hit by light and then rolls into contact with the toner cassette of the printer. Toner is a fine powder that is attracted by charged areas of the drum. The drum then rotates and comes into contact with the paper where the toner is stored. After the paper passes through the high -temperature fixar that melts the toner on the paper, the printed page appears.

LED printers use LEDs with a single LED for each picture. For example, a printer with a 600 resolutionDot-inch (DPI) and 8-inch (20 cm) The printing surface would have 4,800 LEDs. These are cheap producing and extremely reliable, with life rated in thousands of hours. In the laser printer, the drum is illuminated by a movable laser beam from which it passes through rotating mirrors and lenses. The complexity of this system tends to make laser printers noisier, more expensive and less reliable.

Printer technology that uses LEDS has historically had a number of disadvantages that come from using a fixed LED field. Production practicality made it difficult for small LEDs for LED printers to exceed 600 DPI resolution, while laser printers easily exceed 1,200 dpi. In addition, because the LEDs cannot always turn on and off quickly and purely and tend to sometimes produce blurred printed images that cannot correspond to the sharpness of the laser printer.

Since the end of 2011, LED printers have the quality of the output, which is essentially indistinguishable from laser printers. In factThose because they look and behave like laser printers, many retailers are mistaken like laser printers. Given many users began to unknowingly integrate LED printing technology into their homes and offices.
