Okidata C6150DN Toner | Compatible 43865717 Cartridges

C6150DN

The Okidata C6150DN is a networked color laser printer with two-sided printing, made for teams that produce professional-quality documents in house. Its toner set is black 43865720, cyan 43865719, magenta 43865718 and yellow 43865717 — four separate cartridges, one per color, each replaced on its own schedule. Those four numbers are the complete story for this machine: no standard-versus-high-yield split, just the right cartridge in the right slot.

The DN configuration is the shared-office specification: a network connection so the whole team prints to one machine, and duplexing so reports and drafts come out two-sided without a second pass through the tray. A workgroup printer like this earns its keep on presentation work — charts, proposals and client documents — which is presentation and graphics work that leans hardest on the cyan and magenta cartridges. Compatible cartridges keep that output economical while holding the color quality the machine was bought for.

Which cartridge should you buy?

Most of the time, buy the single color that has run out. The four cartridges empty at different rates — black fastest on text-heavy work, the colors on graphics — and swapping only the dry slot is the cheapest way to run this printer. A full four-color set makes sense when several cartridges are low together, when the machine is new to you and its supply history is unknown, or when you want a complete refresh before a heavy print period. One more economy: for internal drafts, choose black-and-white or grayscale in the driver and the C6150DN prints from the black cartridge alone, leaving the three colors untouched for work that needs them.

Chip, toner and everyday use

The printer tracks each cartridge through its chip and reports levels per color, so check the status page before a long color run rather than discovering an empty slot halfway through it. If a compatible cartridge is not recognized at first, take it out and reseat it firmly — recognition problems on this family are usually a seating issue, not a bad cartridge. Quoted yields assume roughly 5% coverage; a deck of full-bleed slides uses toner many times faster than a memo. Keep one spare of the color your team burns through fastest, stored sealed and flat.

Frequently Asked Questions

What toner does the Oki C6150DN use?

Black 43865720, cyan 43865719, magenta 43865718 and yellow 43865717. Match the number to the color on the cartridge label when you reorder — the four numbers run in reverse order, which trips up more than one office.

One color is missing from my C6150DN's charts. What happened?

A completely absent color means that color's cartridge is empty or not seated properly. Check the toner status for the missing color, reseat its cartridge, and replace it if the status reads empty.

Can the C6150DN print in black only to save color toner?

Yes. Select black-and-white or grayscale in the driver and the job runs on the 43865720 black cartridge alone. It is the simplest way to stretch the three color cartridges through a text-heavy month.

Do the DN letters change which cartridges I buy?

No. Duplex and networking are hardware configuration; every C6150 configuration uses this same four-cartridge set, so a spare bought for this machine also fits its siblings below.
