C5450

Rounding out the C5400 generation, the Okidata C5450 is a color laser printer for offices that produce high volumes of color documents. It uses Type C6 toner — black 42804504 with yellow 42804501, magenta 42804502 and cyan 42804503, the standard cartridges rated at 3,000 pages each — and when the monthly page count climbs, the high-yield colors to order are 42127401 yellow, 42127403 cyan and 42127402 magenta, all stocked on this page.

The C5450 was the step-up model of its line, pitched at offices whose color output is a product in itself — client documents, marketing pieces, reports that leave the building. Print like that is unforgiving about interruptions and about color consistency, which shapes how its toner should be bought: keep the full set in reserve rather than discovering an empty color the morning of a deadline. Because the C5450 shares its cartridges with the entire C5400 generation, an office running two models from the family stocks one shelf, not two.

Which cartridge should you buy?

The standard Type C6 cartridges are rated at 3,000 pages each, and for an office printing color in bursts they are a perfectly good fit. The high-yield colors stocked on this page earn their place when the C5450's volume is steady: longer runs between changes and a lower cost per page on the documents that matter most. Whichever capacity you choose, swap colors individually — presentation work drains cyan and magenta faster than yellow on most palettes, and replacing a set wholesale throws away the remainder in the surviving cartridges. The black position takes the standard 42804504. Every compatible cartridge here is covered by a 1-year warranty and 1-year returns.

Chip, toner and everyday use

Color-critical work makes cartridge handling worth a moment of care. The C5450 reads each cartridge's chip to confirm the color position and track usage, and compatible cartridges with the correct chip are recognized on installation. Yield ratings assume 5% coverage; a full-color page can carry ten times that, which is why a cartridge that lasts months on correspondence may last weeks on brochures. For consistent color, avoid mixing a nearly empty cartridge with fresh ones on an important run — output can shift subtly as a cartridge nears the end. Store spares sealed and flat, and let a cold cartridge from a winter delivery warm to room temperature before fitting it.

Frequently Asked Questions

What toner fits the Oki C5450?

The Type C6 set shared with the C5300 and C5400 series: black 42804504, yellow 42804501, magenta 42804502 and cyan 42804503, with the standard cartridges rated at 3,000 pages each.

Which high-yield colors does this page stock for the C5450?

All three: 42127401 yellow, 42127403 cyan and 42127402 magenta. They are the high-capacity versions of the same Type C6 colors.

Why do my C5450 colors look different from my monitor?

Screens emit light while the printer lays toner on paper, so exact matches are unlikely; run the printer's color calibration and use the manufacturer's color profiles for the closest result. Fresh, correctly seated cartridges rule out toner as the cause.

Can I run the C5450 on only black for a while?

Most color lasers will keep printing black-only documents with an empty color cartridge installed, but the empty unit must stay in the machine — the slots cannot be left open.
