C5500MFP

The Okidata C5500MFP takes the C5500 color laser engine and adds copying, scanning and faxing to make a full multifunction office machine. Its toner is OKI’s Type C8 family, and this page stocks the high-yield cartridges: black 43324404, cyan 43324403, magenta 43324402 and yellow 43324401. The standard-capacity line — 43381901, 43381902, 43381903 and 43381904 — fits the same four slots.

A multifunction machine consumes toner through its copier as well as its printer, and copies are easy to forget when estimating how long a cartridge will last. Offices that copy in color as well as print in color should expect the color cartridges to move faster than a print-only machine would suggest.

Which cartridge should you buy?

Only the high-yield line is stocked here, and for a machine that prints and copies all day that is the right emphasis: longer intervals between swaps and a lower cost per page across both workloads. Replace each color as it empties rather than changing the set, and keep one spare black on hand — black serves both the print queue and the copy deck. A four-color set makes sense when levels drop together or as a reserve for a machine the office cannot afford to have idle. If your MFP shares an office with other C5500-family machines, one spare set covers them all, since the cartridges are shared across the family.

Chip, toner and everyday use

Copy density is a separate control-panel setting from print density on this machine, so copies that look darker than prints are an adjustment, not a toner problem — lower copy density a notch and leave the print settings alone. When fitting a cartridge, push it home until it seats with a click so the chip makes contact; a cartridge the machine cannot read usually just needs reseating. Store unopened spares flat, out of direct light, and rotate stock so the oldest cartridge is used first.

Frequently Asked Questions

Which toner does the OKI C5500MFP use?

Type C8 toner: standard black 43381901, cyan 43381902, magenta 43381903 and yellow 43381904, or the high-yield 43324404, 43324403, 43324402 and 43324401 stocked on this page. The copy, scan and fax functions do not change the cartridges.

Do I need different toner for the C5500MFP than for the C5500N?

No. The C5500MFP, the C5500N, the C5500Ldn and the C5900 all share the same 43381901-series cartridges and their high-yield equivalents, so one spare set supports a mixed office.

Copies from my C5500MFP look darker than prints. Can I adjust that?

Yes. Copy density is set separately from print density on the control panel. Lower the copy density a notch and copies will match your prints, without changing toner use on computer print jobs.

Does copying use the same cartridges as printing?

It does — one set of four cartridges serves every function. Heavy color copying will shorten the life of the color cartridges just as color printing does.
