LED printing technology
LED printing borrows a large portion of technology from laser printing. The basics of both are essentially the same – a light source projects an image onto an image drum. The drum is then electrically charged, where toner particles will stick to. Finally, the drum moves over the paper, where the toner will stick onto the paper via direct contact and heat.
One of the advantages that LED printers have over laser printers is that most LED printers are simple in nature, so identifying and rectifying a problem is made much easier. In addition, the LED printing technology used in OKI printers are able to provide a light source that’s more focused, allowing for clear, highly detailed image printouts.
The first printer to feature LED printing technology was the OKI OPP6100. This printer used a magnetic single-component system with a pressure-fixed toner. This design essentially meant that it was a highly efficient printer for its time. Due to LED technology being in its infancy though, mass producing the OPP6100 was something that just wasn’t feasible. In 1983 though, the company announced a second generation LED printer that went by the model number OPP6220. This printer was able to print B4-sized printouts and offered print speeds of up to 20 pages per minute. The OPP6220 was the world’s first mass-produced printer with LED printing technology. Today, OKI still remains one of the best names when it comes to LED printing.
