TASKalfa 5550ci

Kyocera TASKalfa 5550ci printer

Stepping up to the 55-page-per-minute class, the TASKalfa 5550ci is the faster sibling of the 4550ci, aimed at floors where the print queue never quite empties — and it runs the very same TK8507 four-color toner set, so consumable planning stays simple: TK8507K black rated up to 30,000 pages, with TK8507C cyan, TK8507M magenta and TK8507Y yellow at up to 20,000 pages each. This page additionally stocks TK8309 sets for the family's smaller models, around the TK8309K black and its TK8309C, TK8309M and TK8309Y color companions.

More speed, same cartridges — that is the whole upgrade story here. Mixed fleets running the 4550ci and 5550ci need only one toner stock, one shelf and one set of part numbers for the purchasing file. The faster engine simply burns through that shared stock sooner, which changes how much you keep on hand, not what you keep. For a floor whose bottleneck is the queue rather than the walk to the supply cabinet, that is exactly the right trade.

Which cartridge should you buy?

At 55-ppm-class volume, the question is less which cartridge and more how deep the shelf should be. Black multipacks — three or five at a time — match the pace of a busy floor and keep the reorder cycle calm. Colors still empty individually, so single-color replacement remains the routine; hold the big five- and eight-cartridge sets for fleet refreshes or the day several colors report low together. And because the 4550ci below it drinks from the same stock, a spare bought for one machine is quietly a spare for both.

Chip, toner and everyday use

High-throughput machines reward small habits. Swap a cartridge as soon as the machine calls it empty rather than nursing faded output — at this speed a weak cartridge costs more in reprints than it saves in toner. Keep the replacement sealed until the moment of the swap, seat it fully so the chip registers, and let the printer confirm the new cartridge's rated life before releasing a long job. Yield ratings follow ISO/IEC 19798 at standard test coverage; heavy color coverage on large pages is the fastest way to come in under them, so judge your stock by your busiest week.
