C5150N

The OKI C5150N is a network-ready color laser printer from the Type C6 generation, made for offices that need shared color printing without fuss. Its standard toner set is black 42804504, cyan 42804503, magenta 42804502 and yellow 42804501, and for heavy use the family adds the 42127400 high-capacity series — 5,000-page versions of the three colors. This page lists those high-capacity colors: 42127403 cyan, 42127402 magenta and 42127401 yellow, both as plain singles and under the C5100n listing names, plus three- and six-color sets.

A networked printer lives a different life from a personal one: it sits in a shared space, takes jobs from a whole team's computers, and its toner warnings are everybody's problem and nobody's job. That is the practical case for the 5,000-page fills on this page — they stretch the interval between warnings on a machine whose printing nobody individually tracks. The C5150N also rewards a small stocking habit: one spare set on the shelf near the printer, because a shared machine never runs dry at a convenient moment.

Which cartridge should you buy?

Start with the singles if only one color is low — the C5150N tracks each color separately, and there is no reason to retire a half-full magenta because the cyan gave out. The 3 Color Set makes sense when several colors are aging together or when a new machine is being stocked from empty, and the 6 Color Set is the shelf-stocking option for offices that go through colors quickly and want the next change already on hand. All of them are the 5,000-page high-capacity fills; on a shared printer that capacity is usually worth more than the modest saving of the standard fills, simply because every cartridge change on a networked machine interrupts somebody. Black is not part of this page's listings — the C5150N's black sits under the standard code 42804504.

Chip, toner and everyday use

Compatible Type C6 cartridges carry the contact chip the printer reads; fit them with seals removed and a firm push until they seat, and the C5150N should register the new fill without protest. If the colors on a page look different from last month, suspect the room before the toner: temperature, humidity and a changed driver profile all shift output, and running the printer's color calibration usually restores the balance. Keep network-printer spares sealed and stored near the machine — a spare kept across the building is a spare that arrives late.

Frequently Asked Questions

Which toner cartridges fit the OKI C5150N?

The standard set is black 42804504, cyan 42804503, magenta 42804502 and yellow 42804501. The high-capacity colors stocked on this page are 42127403 cyan, 42127402 magenta and 42127401 yellow, each a 5,000-page fill.

What does the N add over the C5150?

Networking. The C5150 and the C5150N are the same Type C6 engine; the N model connects to the office network so a whole team shares it, while the base model serves a single desk. The toner family is identical on both.

Why do some listings here say C5100n?

Those are the same 4212740x high-capacity cartridges listed under the sister model's name — the C5100n belongs to the same Type C6 family and takes the identical cyan, magenta and yellow cartridges. The cartridge inside is the same either way.

The colors look different from last month. Why?

Toner formulation is consistent, so drift usually comes from the environment or settings: temperature, humidity, or a driver profile that changed. Run the color calibration and confirm the driver profile matches the one you used before.
