LEDprinters
LEDprinters, often written as LED printers, are a class of electrophotographic printers that use an array of light-emitting diodes as the exposure source instead of a laser diode. The LED array writes the latent image on a photoconductive drum or belt, which is subsequently developed with toner.
The charged surface is exposed by the LEDs to create an electrostatic image; toner is attracted to
Many LEDprinters employ either a full-width LED array that exposes the entire page in one pass or
Advantages include fewer moving parts, reduced mechanical wear, and potentially higher reliability. LEDs have long lifetimes,
Disadvantages include higher upfront cost for color models and the need for a wide LED write head
LED printing technology became commercially available in the late 20th century as an alternative to laser
