LED print­ing tech­nol­ogy

HWM (Malaysia) - - SPECIAL -

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.
