C5500Ldn

The Okidata C5500Ldn is a network-ready color laser printer positioned for departments that lean heavily on color output. It belongs to the OKI Type C8 cartridge family, running the standard 43381901–43381904 cartridges in its four slots, and this page stocks the high-yield version of the same family: black 43324404, cyan 43324403, magenta 43324402 and yellow 43324401.

The L in the name is the lower paper tray configuration bundled with the machine, alongside duplex printing and networking. Two trays let a department keep letter paper in one and legal stock or letterhead in the other, with the printer pulling from the right tray for each job — a setup that suits offices mixing everyday correspondence with longer color documents.

Which cartridge should you buy?

Departments that lean on color go through cartridges quickly, which is why the high-yield line is the stocked range here: each cartridge covers substantially more pages than the standard version, so swaps are less frequent and the cost per page drops. Buy the colors individually as they run down — a department doing blue-heavy reports may empty cyan well ahead of the others — and take a four-color set when the levels fall together or as shelf stock. The standard 43381901–43381904 cartridges fit the same machine if your volume is light, but they are not sold on this page.

Chip, toner and everyday use

The quickest saving on this printer costs nothing: set the driver to black-and-white by default, so the cyan, magenta and yellow cartridges only engage for pages that truly need color. Many departments cut color toner use sharply with that one setting. When a cartridge is installed, the printer reads its chip and reports the level for that slot; if a new cartridge is not recognized, reseat it firmly and restart the machine before assuming it is faulty.

Frequently Asked Questions

Which cartridges does the OKI C5500Ldn take?

Type C8 cartridges: black 43381901, cyan 43381902, magenta 43381903 and yellow 43381904, or the high-yield 43324404, 43324403, 43324402 and 43324401 stocked here. The tray, duplex and network configuration does not change the cartridge set.

What does the L in C5500Ldn stand for?

It marks the second paper tray bundled with the printer. With two trays you can keep letter paper in one and legal or letterhead in the other, and the printer selects the correct tray automatically.

How do I reduce color toner waste on the C5500Ldn?

Make black-and-white the driver default and switch to color deliberately for the jobs that need it. Email, drafts and internal forms rarely justify color toner.

Can I mix standard and high-yield cartridges in the same machine?

Yes. Each slot reads its own cartridge, so a high-yield black can run alongside standard colors. Just match each part number to the color of the slot it goes into.
