C8600

The Okidata C8600 is a color laser printer from OKI's C8000 series, aimed at offices that need dependable color output in a compact footprint. Its cartridge set pairs the 43487736 black cartridge with three color cartridges — 43487735 cyan, 43487734 magenta and 43487733 yellow — each of the colors rated at 6,000 pages. This page stocks the three colors; the black cartridge is not among the listings here, so check the number on your installed cartridges before ordering, as the machine's own documentation advises.

The C8600 uses the same cartridge set as the C8600DN and the C8800dn, so offices running any of these models work from one color shelf. In daily use it is a straightforward four-position machine: colors drain independently, most offices find one or two colors doing the real work while the third lasts far longer, and a 6,000-page rating per color means replacements are occasional events rather than a routine.

Toner Cartridges for C8600

One gap to know about: the black cartridge for this machine, 43487736, is not stocked on this page. The three cartridges above are the complete color range listed here — if your C8600 needs black, it has to come from a listing that carries that number.

Which cartridge should you buy?

Replace the single color that has run out — the three positions are independent, and a fresh cartridge works fine alongside older ones, so there is no need to retire colors that still have toner in them. When all three colors are low in the same period, the 3 Color Set renews the set in one order; the 6 Color Set doubles up on each color and suits an office that would rather restock colors twice a year than think about them quarterly. Because every color here is the same 6,000-page cartridge, the decision is about how many you want on the shelf, not about which tier to pick. The compatible cartridges on this page are covered by a 1-year warranty and 1-year returns.

Chip, toner and everyday use

If color areas start showing white gaps, a color cartridge running dry is the first suspect — check the levels of the three colors before anything else. If the gaps appear right after a cartridge change, take the cartridge out and reseat it; a cartridge sitting slightly high can interrupt toner flow even when it shows as installed. Mixing old and new cartridges is normal on this machine, since each color is independent. Keep spares sealed in a cool, dry spot, and rock a cartridge gently side to side before installing one that has been in storage, so the toner inside is evenly distributed.

Frequently Asked Questions

What cartridges does the Oki C8600 take?

The C8600 uses yellow 43487733, magenta 43487734, cyan 43487735 and black 43487736 — the same set as the C8600DN and C8800dn. One four-cartridge set covers these models; this page stocks the three colors.

Why is there no black cartridge listed on this page?

Only the three color cartridges are stocked here. Black for the C8600 is the 43487736 cartridge, and it is simply not part of this page's listings, so it needs to be sourced from a listing that carries that exact number.

My C8600 prints have white gaps in color areas. What is the cause?

White gaps in color areas often mean a color cartridge is running dry, so check the color levels first. If a cartridge was just replaced, remove and reseat it to make sure toner flows properly — that resolves the gaps in most cases where the cartridge itself is fine.

Can I mix old and new cartridges in the C8600?

Yes. Each color is independent, so a new cartridge works fine alongside older ones that still have toner. Replace only the depleted color rather than the whole set, and let each cartridge give you its full life.
