Okidata C5850 Toner | Compatible 43865724 Cartridges

C5850

The Okidata C5850 is a wide-format color laser printer aimed at offices and marketing departments that need tabloid-size color produced in-house. It takes four individual toner cartridges — black 43865720, cyan 43865719, magenta 43865718 and yellow 43865717 — each in its own slot, each replaced separately as it runs down. Compatible cartridges in these part numbers keep oversize color output affordable.

Wide-format work changes the toner equation: a single tabloid proof can lay down as much color as several letter pages, so marketing teams that proof posters, sell sheets and signage in-house go through color cartridges faster than a documents-only office would. Watching which color your artwork leans on is the key to keeping this machine fed.

Which cartridge should you buy?

For most C5850 owners the pattern is simple: buy black in the multipacks if your wide-format work is text- and layout-heavy, because black still does most of the work even on big pages, and replace the three colors one at a time as each empties. A full four-color set earns its place when several levels drop together, or before a large proofing run you cannot afford to interrupt. There is no separate high-yield line on this page, so the practical economy is in matching pack sizes to your real usage instead of keeping deep stock of a color your artwork rarely touches.

Chip, toner and everyday use

When the printer warns that a cartridge is low but the pages still look good, keep printing: remove the cartridge, shake it gently from side to side to redistribute the toner inside, and reinstall it — replace it only when output actually fades. The chip in each cartridge reports its own level, so the warning always names the slot that needs attention. Store spare cartridges away from heat and light; wide-format spares are a real investment, and a cool, dark shelf keeps them ready.

Frequently Asked Questions

What toner cartridges does the C5850 use?

Four individual cartridges: black 43865720, cyan 43865719, magenta 43865718 and yellow 43865717. Each color is replaced on its own when it runs out; you never have to change the whole set for one empty slot.

My C5850 warns toner is low but pages still look good — can I keep printing?

Usually yes, for a while. Take the low cartridge out, shake it gently side to side to level the remaining toner, and put it back. Replace it when prints genuinely start to fade.

How do I clean the LED printheads on the C5850?

Thin white lines down the page usually mean a dirty LED lens, not empty toner. Wipe the four LED arrays inside the printer with a dry, lint-free cloth, then print a test page to confirm.

Does the C5850 use a separate drum I need to order?

The cartridges stocked for this model are the four toner cartridges listed above. Order by the part number on the cartridge you remove, and the replacement will match the slot.
