Aficio SP C431DNHT
The Ricoh Aficio SP C431DNHT is the tall configuration of the SP C431DN color laser, built with expanded paper capacity for workgroups whose color jobs run long. Its color engine, networking and duplex unit match the standard C431DN exactly, so print quality is identical — the HT simply holds more paper between refills. It prints from the 821105 toner family: black 821105 rated for up to 24,000 pages, plus cyan 821108, magenta 821107 and yellow 821106, each rated for up to 21,000 pages. Everything on this page is a compatible version of those four cartridges, sold as singles, black multipacks and color sets.
A tall paper supply earns its keep when output comes in long, unbroken runs — a training manual for the whole department, a stack of end-of-month reports, handouts for a full day of meetings. On a standard tray those jobs pause for reloading; on the C431DNHT they finish in one pass. Offices that chose this variant usually did so because someone was tired of babysitting the printer mid-job, and the cartridges below are stocked with that same no-interruption mindset.

Which cartridge should you buy?
Start with black. In everyday office color printing — documents with a color header, a chart here and there — the 821105 black cartridge does most of the work and is the first to empty, so its 24,000-page rating matters more than any other number on this page. If the HT prints daily, a black 2-pack, 3-pack or 5-pack keeps a spare on the shelf and lowers the cost of each page; a single is fine for occasional use. The three colors each last up to 21,000 pages and run out at different times depending on what you print, so replace them one at a time as each fades rather than swapping the full set. Choose the 3 or 6 color set when you want a complete color refresh in one order, or a full spare set ready before a long run. Every cartridge listed here is a compatible replacement backed by a 1-year warranty and 1-year returns.
Chip, toner and everyday use
Each cartridge on this page carries a working chip, so the C431DNHT recognizes it on installation and reports toner levels normally. Fit a new cartridge by removing all of its packaging and the protective seal, then slide it in until it seats firmly. Page ratings assume about 5% page coverage, so dense full-color pages will use toner faster than the headline numbers suggest. If output starts to look faint near the end of a cartridge's life, take it out and rock it gently from side to side a few times — redistributing the toner inside often restores even coverage for a while longer. Keep spare cartridges sealed, stored flat and away from heat until the day they are needed.
Frequently Asked Questions
Does the tall HT configuration need a different cartridge from the regular SP C431DN?
No. The tall configuration changes paper capacity only. The C431DNHT uses the same 821105 black, 821108 cyan, 821107 magenta and 821106 yellow cartridges (also marked SP C430A) as the base model, and they are fully interchangeable.
My printer says the yellow cartridge is empty. Do I have to replace all four?
No — each color is a separate cartridge. Order the 821106 yellow on its own and leave the other three in place until they run low in turn.
How many pages should I expect from the black cartridge?
The 821105 black is rated for up to 24,000 pages at roughly 5% coverage. Text documents with light color will land near that figure; pages with heavy color graphics will finish a cartridge sooner.
Are these genuine Ricoh cartridges?
They are compatible replacements made for the SP C431DNHT, each with a functioning chip. They are covered by a 1-year warranty and 1-year returns.
