Digital LED and laser printers are both examples of electrophotographic technology.
LED (Light Emitting Diode) printheads use a single, pixel-size, modulating light source to
recreate images. This beam emanates from a stationary array containing thousands of LEDs.
Light from each diode passes through a focusing lens onto an image drum that serves as a
photoreceptor. Toner is attracted to this latent image and transferred to the paper. (Fig. 1)

Laser printheads also use a single light source. However, this beam is aimed at a revolving
mirror that reflects it through a series of focusing lenses and off a mirror to an image drum.
Lasers produce the same result as Digital LEDs but with many more moving parts. (Fig. 2)
Given the number of moving parts, it can be costly and time-consuming to repair a laser
printhead — a headache that OKI printer owners are spared.

OKI toner-based printers employ Digital LED Technology. We are so confident in the
reliability of our printers that we offer a 5-year limited printhead warranty, the longest in
the industry and much longer than the typical one-year on laser printheads.
