LED printer

LED printers actually use a linear array of light-emitting diodes to "write" the light on the drum.

In a laser or LED printer, modulated light is projected onto the drum surface to create the latent image.

An LED printer is a type of computer printer similar to laser printer.

Xerography is now used in most photocopying machines and in laser and LED printers.

The same process is used in microform printers and computer output laser or LED printers.

Depending on design, LED printers can have faster rates of print than some laser-based designs, and are generally cheaper to manufacture.

It is an LED printer, meaning it uses light-emitting diodes instead of lasers and mirrors to produce images.

Other uses are as UV curing devices for some ink and coating methods, and in LED printers.

In an LED printer, the complex laser and mirror system is replaced by a semiconductor diode that glows when it is electrically charged.

This technique is based on the process principles of xerographic printers, (for example, laser or LED printers) that combine electrostatic printing with photography.

In contrast to LED printers, laser printers have to rely on elaborate combinations of rotating mirrors and lenses that must remain in alignment throughout their use.

Another toner-based printer is the LED printer which uses an array of LEDs instead of a laser to cause toner adhesion to the print drum.

Kodak's new Ektaplus is an LED printer, using a light-emitting diode, and it differs from laser printers in several ways, though not in the finished look of the printed page.
