TASKalfa 4550ci
The TASKalfa 4550ci anchors Kyocera's 45-page-per-minute class of A3 color multifunction systems, and it runs the long-life TK8507 toner set: TK8507K black, rated for up to 30,000 pages, plus TK8507C cyan, TK8507M magenta and TK8507Y yellow at up to 20,000 pages each. This page also stocks TK8309 color sets for the smaller TASKalfa models in the family — their black cartridge is the TK8309K, with the TK8309C, TK8309M and TK8309Y colors covered by the same sets.
Departments land on the 4550ci when they have outgrown desktop color printers and need A3 output without stepping up to the flagship tier: the balance here is speed, paper capacity and cost control. It is shared infrastructure rather than someone's personal printer, and its toner set is sized for that role — a 30,000-page black cycle means the supply conversation happens a few times a year, not every month. Keep the distinction straight when ordering: this machine takes TK8507; the TK8309 sets below belong to its smaller siblings.

Which cartridge should you buy?
For the 4550ci itself, think in long cycles. The black cartridge's 30,000-page rating means a single spare covers most departments for months; buy the two- or three-black multipacks only when monthly volume is genuinely high, and let the five-black pack serve multi-machine floors. Colors at 20,000 pages each usually empty one at a time — replace the named color and move on. The large multi-color sets (five and eight cartridges) make sense when a department is standardizing a fresh stock or refreshing every color at once, not for routine top-ups.
Chip, toner and everyday use
On this platform the toner cartridges and the imaging components are separate: when a cartridge runs down you replace toner only, and the machine tracks toner life and maintenance items independently. That separation is why the rated yields can be so long — and why a fading page almost always means toner, not a worn drum. Install each cartridge with its chip facing the reader, push it home until it locks, and give the printer a moment to register the new rated life before sending a large job. Yields are rated per ISO/IEC 19798; A3 pages and dense color coverage consume proportionally more than the letter-size, light-coverage test basis.
Frequently Asked Questions
Which toner cartridges does the TASKalfa 4550ci use?
The TK8507 set: TK8507K black rated up to 30,000 pages and TK8507C, TK8507M and TK8507Y rated up to 20,000 pages each, measured per ISO/IEC 19798. Each color is ordered and replaced individually.
Will the TK8309 sets on this page fit the 4550ci?
No. The TK8309 family belongs to the smaller TASKalfa 3050ci and 3550ci models listed below; the 4550ci itself takes TK8507 cartridges. The sets share this page because the models share one product family, not because the cartridges interchange.
Does the 4550ci use a separate drum unit?
Yes — toner and the imaging components are separate on this model, and the printer tracks them independently. When output fades at the end of a cartridge's rated life, replacing the toner cartridge is the fix; you are not replacing the imaging system with it.
What warranty covers the compatible cartridges?
Every compatible cartridge listed here carries a 1-year warranty and 1-year returns.
