Ricoh Aficio SP C320DN Toner Cartridges (Compatible)

Aficio SP C320DN

Near the top of its color generation sits the Ricoh Aficio SP C320DN, pairing standard duplex and network connectivity with the stamina to handle color printing by the ream. Its toner appetite is served by the 406475 black cartridge at up to 6,500 pages and the 406476 cyan, 406477 magenta and 406478 yellow cartridges at up to 6,000 pages apiece. Those are departmental-class ratings, suited to a machine expected to keep pace with a busy floor rather than an occasional user.

The C320DN is the sort of printer a department standardizes on when color output is heavy and constant: client-facing documents, internal reports full of data graphics, training material run in batches. A machine in that role cannot afford to sip toner in small doses, so the platform's high-yield cartridges and the deep multipacks sold for them are as much a part of the package as the printer itself. One shared supply set across the wider family also simplifies life for whoever manages the stock cupboard.

Which cartridge should you buy?

Volume is the deciding factor on this page. A C320DN working through reams will cycle black fastest, and the 3- and 5-count black multipacks exist precisely to keep that slot fed without repeat orders. For scheduled refreshes, the four-color sets replace everything at once, and the 8-count set is the deep-stock option for offices that service several machines on this platform. Colors can still be bought singly: when one of the 6,000-page color cartridges fades ahead of the others, there is no reason to retire the rest early. Every cartridge sold here is a compatible replacement with a working chip, a 1-year warranty and 1-year returns.

Chip, toner and everyday use

High-volume machines reward a small stock of spares and a calm replacement routine. The chip in each cartridge reports identity and remaining life to the printer, so watch the status page rather than guessing. When fitting a fresh unit, tilt it gently a few times to distribute the toner, align it with its color-coded slot, and press until it seats. Keep boxed spares in the supply cupboard rather than on top of the warm printer, and note that yield figures are measured at about 5% coverage: presentation decks and photo-heavy pages spend toner far faster than text.

Frequently Asked Questions

What toner does the SP C320DN use?

The four-cartridge set is 406475 for black, 406476 for cyan, 406477 for magenta and 406478 for yellow. The numbers are printed on each old cartridge, and matching them is the surest way to reorder the right unit.

Is there a higher-yield option for this printer?

The cartridges on this page are already the high-yield family for this platform, up to 6,500 pages in black and 6,000 per color. The way to stretch supply further is pack size: black multipacks and the larger color sets reduce how often you reorder, not the rating of each individual cartridge.

Do these cartridges fit older SP C310-family models?

Yes, the set is shared across the family, including the Aficio SP C311N and the Aficio SP C312DN. Stock kept for the C320DN can cover those machines too.

Are the cartridges on this page original Ricoh or compatible?

They are compatible cartridges built for this printer, each with a functioning chip, and they carry a 1-year warranty with 1-year returns. They are made to match the page yields shown in the table above.
