C8600DN

The Okidata C8600DN is a duplex, networked color printer in OKI's 8000-series workgroup line — a department machine rather than a desk printer. Its cartridge set is cyan 43487735, magenta 43487734 and yellow 43487733, with black 43487736 completing the four slots; supplier listings for this family should always be checked against the cartridge already in the machine before reordering.

The DN hardware — automatic two-sided printing and a network port — points at a printer shared by a group and left to get on with it. Toner care on such a machine is mostly about not being caught out: the colors are consumed unevenly depending on what the department prints, and the cartridge that empties is rarely the one anyone predicted.

The family's black cartridge is 43487736; it is not among the listings on this page, which stocks the three colors above.

Which cartridge should you buy?

There are no multi-packs on this page, so the buying decision is simply which single color the printer is asking for — replace that one and leave the rest. If your department prints color daily, hold one spare of the color that historically drains first; if color is occasional, order on the warning and let the remaining toner in the other two colors carry you meanwhile. For black, note the number 43487736 and source it by that code, since it is not stocked here.

Chip, toner and everyday use

Each cartridge is chipped and the printer tracks the three colors and black independently, so the low warning names the exact slot. Before a long duplex run, check the levels — a color giving out halfway through a two-sided job wastes paper as well as time. A cartridge that prints faintly before its warning can often be revived for a while by removing it and rocking it gently side to side to loosen settled toner. Keep spares sealed in a cool spot near the machine.

Frequently Asked Questions

Which cartridges fit the C8600DN?

Yellow 43487733, magenta 43487734, cyan 43487735 and black 43487736 — the same set as the rest of the C8600 and C8800 family. The DN suffix adds duplex and networking; it changes nothing about toner.

Why is the black cartridge not listed on this page?

The listings stocked here are the three color cartridges. Black for this family is 43487736; order it by that exact number rather than substituting a black from another OKI line, which will not fit.

My pages show ghost images. Is the toner to blame?

Ghosting — a faint repeat of an earlier image — usually comes from a worn drum or fuser, not from the toner cartridges. Low toner causes fading, not ghost patterns, so check the drums if the ghost repeats at regular intervals.
