C5250DN

Duplexing and networking are built into the Okidata C5250DN, a shared-office color printer that keeps two-sided jobs moving without a print server in the middle. Its toner is the Type C6 set — black 42804504, cyan 42804503, magenta 42804502 and yellow 42804501 — common across the C5100, C5200, C5300 and C5400 generation of OKI color machines. This page stocks the high-yield color step-up: 42127403 in cyan, 42127402 in magenta and 42127401 in yellow.

Two-sided printing halves paper, not toner — a fact worth keeping in view when this machine's color use looks high. Every duplexed page still lays down the same coverage as a single-sided one, so a department that prints long color documents on both sides spends its colors at the full rate while feeling economical. Budget the cartridges by pages imaged, not by sheets consumed, and the numbers stop surprising you.

Toner Cartridges for C5250DN

42127403 — Cyan, High Yield — the deeper cyan fill for this duplex workhorse.
42127402 — Magenta, High Yield — high-capacity magenta, swapped on its own schedule.
42127401 — Yellow, High Yield — the high-yield yellow cartridge.

The three listings above are the high-yield colors. The standard-capacity Type C6 cartridges — the 42804501 through 42804504 numbers — remain the lighter-fill alternative for each slot.

Which cartridge should you buy?

A duplexing shared printer justifies the deep fills sooner than most. Its colors serve every department that prints to it, and two-sided color work doubles the pages each job pulls from the same cartridges. Choose the high-yield colors when the C5250DN is the office's default color machine; stay with standard fills only if color is genuinely occasional — a few charts a month will not trouble either capacity. As everywhere in this family, colors are replaced one at a time, so a step up can happen color by color as each standard cartridge finishes.

Chip, toner and everyday use

Color that drifts out of alignment is a registration issue before it is a cartridge issue: run the color registration adjustment from the printer's menu, which prints a test pattern and realigns the four LED printheads. If misalignment keeps returning, look at the levels — a color running near empty can drag registration with it, and replacing that one cartridge settles both complaints. Once the printer is on the network, each computer needs its own driver install; after that, the machine behaves like any local printer for everyone in the office.

Frequently Asked Questions

Which cartridges fit the C5250DN?

The Type C6 family: 42804504 black, 42804503 cyan, 42804502 magenta and 42804501 yellow in standard form. The high-yield colors stocked on this page are 42127403 (cyan), 42127402 (magenta) and 42127401 (yellow), each replacing its standard counterpart in the same slot.

How do I correct color registration on the C5250DN?

Run the registration adjustment from the machine's menu; it prints a test pattern and realigns the LED printheads. Persistent misalignment after adjustment can point to a nearly empty cartridge in one color — check the levels before assuming a hardware fault.

Can the C5250DN be shared on an office network?

Yes, it is network-ready out of the box. Put it on the LAN, install the driver on each computer, and every workstation can print to it directly — no separate print server is required.

Do duplex jobs use less toner?

No. Duplexing saves paper, not toner: the same pages receive the same coverage whether they land on one sheet or two sides of it. Plan cartridge buying around pages printed, not paper consumed.
