OKI Printers

5 models across 2 product lines.

OKI makes office LED printers — mono (the B series) and colour (the C series), including the wide-format A3 C900 models. OKI’s LED engine works like a laser for running-cost purposes: the drum (image drum) is a separate replaceable part from the toner, with a much longer life, so the true running cost is toner plus the image drum amortised over the pages it lasts. The cost-per-page shown here is toner-based; the image drum, and on the larger models the fuser and transfer belt, are listed as their own supplies. OKI toner often comes in standard and high-yield tiers, and OKI publishes ISO page yields, so a per-page figure is shown wherever a cartridge price is known. OKI’s US product pages were retired after the Americas business changed hands, so the specifications here come from OKI’s own datasheets and the current US supplies are listed with their genuine order codes. Each model below is listed with its specs and the toner, image drum and service parts it uses.
