Aficio SP C312DN
Two-sided color documents without the manual page-flipping are the Ricoh Aficio SP C312DN's defining trick: automatic duplex and network sharing in one color laser built for workgroup duty. It feeds on the same generous toner set as its close relatives, the 406475 black cartridge good for up to 6,500 pages, plus the 406476 cyan, 406477 magenta and 406478 yellow cartridges at up to 6,000 pages each. Four independent cartridges keep replacement simple: open the cover, swap the empty one, and keep printing.
Duplex changes the economics of a shared office printer in ways toner ratings alone do not capture. Reports, handouts and draft documents printed on both sides cut paper consumption close to half, and a networked machine spreads that saving across every desk that prints to it. The C312DN tends to land in departments with steady, mixed output, plenty of black text with regular splashes of color, which is exactly the workload its 6,500-page black cartridge is sized to absorb.

Which cartridge should you buy?
Match your ordering to the mix of work. Black runs longest here, so text-heavy teams should anchor on the black singles or the 2-, 3- and 5-count black multipacks and let the colors trail behind, replaced one at a time as the printer reports them low. If a project suddenly turns color-heavy, the complete four-color sets reset every slot in one order, and the 5- and 8-count sets stretch the interval between orders even further. The cyan-magenta-yellow sets in 3- and 6-counts cover the common case where black still has life left but the color trio is fading together. All cartridges here are compatible units with functioning chips, covered by a 1-year warranty and 1-year returns.
Chip, toner and everyday use
The printer talks to a chip on each cartridge to verify the unit and estimate what is left, and compatible cartridges carry chips that speak the same language. Replace a cartridge when the machine asks rather than on a fixed schedule, and give the new unit a few gentle side-to-side tilts first so the powder inside settles evenly. Store spares flat, sealed and out of sunlight. Remember that the published yields assume light 5% coverage: a duplex habit saves paper, while toner use follows how much of each page is actually covered, so graphics-heavy two-sided reports still spend color toner at full rate.
Frequently Asked Questions
Does the duplex unit need a special toner?
No. Duplexing is a paper-path feature, not a supply change: the SP C312DN uses the standard 406475 black and the 406476, 406477 and 406478 color cartridges listed above. The same cartridges serve whether you print single-sided or two-sided.
Which cartridge will I replace most often?
In most offices it is the black 406475, because text dominates shared printing even though its 6,500-page rating is the highest of the four. The colors, rated at 6,000 pages each, typically last longer in calendar time simply because fewer pages use them heavily.
Can I keep printing when one color runs empty?
The printer will prompt you to replace the empty cartridge, and color documents need all four cartridges in working order to come out right. Black-only jobs may continue depending on the job and settings, but keeping one spare of the color you burn through fastest is the surest way to avoid an interruption.
Are these the same cartridges the SP C311N takes?
They are. The Aficio SP C311N and the Aficio SP C320DN share this exact four-cartridge set, so stock bought for one machine covers the others.
