C5150

The Okidata C5150 is a compact color printer built for small offices moving up from inkjet to laser-class color. It belongs to Oki's Type C6 toner family: the standard cartridges are 42804504 in black, 42804503 in cyan, 42804502 in magenta and 42804501 in yellow. This page stocks the family's high-yield color trio — 42127403 in cyan, 42127402 in magenta and 42127401 in yellow — the larger fills offices reach for when the standard colors run out too quickly. No black cartridge is listed on this page; the three cartridges below are the color side of the C5150's toner set.

For a small office, the C5150's appeal is that color stops being an event. A proposal, a report cover or a set of charts prints in-house, in color, without a trip to a copy shop — and because each color is its own cartridge, a heavy month of blue-heavy documents only empties the cyan. Owners who print color most weeks feel the standard fills cycle quickly, which is exactly the gap the high-yield trio on this page fills.

Which cartridge should you buy?

Every cartridge on this page is a high-yield color, so the real decision is about how your office uses the C5150. If color printing is a weekly habit — presentations, invoices with color branding, handouts — the larger 4212740x fills are the sensible default: fewer swaps, fewer orders, and a lower cost per color page than the standard Type C6 cartridges. Replace colors one at a time as each runs out rather than changing the whole set; the printer tracks them independently. Keep in mind the black cartridge is a separate purchase under its standard code, 42804504, and is not part of this page's listings. If your C5150 mostly prints black text with only occasional color, your color cartridges will age slowly — in that case one high-yield set can carry the machine for a long stretch.

Chip, toner and everyday use

Each cartridge carries a contact chip the C5150 reads on installation. Peel every seal and tab before the cartridge goes in, handle it by its ends so the chip stays clean, and push it home until it locks. If the printer questions a cartridge you have just fitted, removing it, wiping the chip contact gently with a dry cloth and reseating it settles most cases. Store spares flat, sealed and away from heat, and keep one spare of the color your office burns through fastest — on most C5150s that is cyan or black, rarely all four at once.

Frequently Asked Questions

Which toner does the OKI C5150 take?

The C5150 uses the Type C6 family: black 42804504, cyan 42804503, magenta 42804502 and yellow 42804501 in standard fill. The high-yield color versions stocked here are 42127403 cyan, 42127402 magenta and 42127401 yellow.

Why is there no black cartridge on this page?

This page lists the three high-yield color cartridges for the C5150. The machine's black cartridge sits under the standard Type C6 black code, 42804504, and is a separate listing — nothing about the color trio changes which black the printer needs.

My C5150 keeps asking for a cartridge I just replaced. What is wrong?

The printer is not recognizing the new cartridge. Take it out, confirm every seal and tab is off, wipe the cartridge's contact chip gently, and reinstall it firmly until it locks. A cartridge that still is not recognized after reseating may be faulty.

How should I dispose of empty C5150 cartridges?

Do not put toner cartridges in regular trash. Use Oki's recycling program or a local e-waste drop-off that accepts toner; many office supply stores take empties back at no charge. Bag empties before transport so residual toner does not spill.
