TASKalfa 400CI

Kyocera TASKalfa 400CI printer

The TASKalfa 400ci anchors the 40-page-per-minute tier of Kyocera's color multifunction range, built for departments where color documents flow all day: networked, duplexing and scan-ready, it covers the full office document workflow in one machine. The toner family Kyocera specifies for it is the TK-857 series — the US form of the TK-855 — with TK-857K black rated at 25,000 pages and TK-857C, TK-857M and TK-857Y at 18,000 pages each per ISO/IEC 19798. Those figures, not the listings below, describe what the 400ci itself drinks.

The listings gathered on this page are a different shelf item: Kyocera TK-592 color sets, stocked here for the related color machines listed at the bottom of the page. Each set is built from the same four cartridges — black TK592K with cyan, magenta and yellow partners — combined into 3-piece color-only sets and 5-, 6- and 8-piece multiples for offices that go through color quickly. If you are supplying a 400ci, check the cartridge code on your machine before ordering: its own family is TK-857, and the TK-592 sets below serve the sibling models instead.

Which cartridge should you buy?

For the machines these sets actually feed, the choice is about how color is consumed. The 3-piece set is one cartridge of each color — the standard refresh when all three colors run low together. The 6-piece color set doubles that, for a workgroup whose output is color-first. The 5- and 8-piece sets add black cartridges into the mix at higher counts, suiting a shelf that restocks in bulk rather than per warning light. Whichever size you pick, confirm the TK-592 code against your printer first — sets are the economical way to buy this family, but only for the models that take it. Every compatible set here is covered by a 1-year warranty and 1-year returns.

Chip, toner and everyday use

Whether it is a departmental MFP or a smaller color machine, the habits that protect print quality are the same. Let the printer read each new cartridge's chip before starting a long run, and keep set boxes sealed until the day of the swap so no cartridge sits open in a dusty supply room. Rated yields are measured at standard coverage, and color work is rarely standard — a month of full-page presentations can halve the interval the rating promises. If a color starts to band or fade, rocking its cartridge gently side to side redistributes the toner and usually restores even output while the replacement is on its way.

Frequently Asked Questions

Which toner does the TASKalfa 400ci use?

Kyocera specifies the TK-857 family for the 400ci (the US version of the TK-855): black at about 25,000 pages and each color at about 18,000 pages. Always order by the code printed on the cartridge you are replacing.

What cartridges are listed on this page?

Kyocera TK-592 color sets in four sizes — 3, 5, 6 and 8 pieces — stocked for the related color models listed below. They are a separate family from the 400ci's own TK-857 toner.

Is TASKalfa 400ci toner the same as TASKalfa 500ci toner?

Yes. The 400ci, 500ci and 552ci all use the identical TK-857 family, so their cartridges are interchangeable across the three models.

How many pages does a TK-857 cartridge print?

Approximately 25,000 pages for the black TK-857K and 18,000 pages for each color cartridge, per ISO/IEC 19798. Actual yield varies with coverage — heavy color work finishes cartridges sooner.
