Also fits: this black cartridge fits the Ricoh Aficio MP C305SP and MP C305SPF — the same machines also sold under the Savin and Lanier brands with the same model names. Ricoh also lists this platform's black cartridge under part number 842119 (12,000 pages).

Frequently Asked Questions

Six of us share one MP C305SPF — how do we avoid running dry at the worst moment?

Shared machines burn black faster than anyone's individual estimate, because nobody counts copies and faxes against themselves. At a combined 2,000 black pages a month, this 12,000-page cartridge lasts about six months; at 4,000 a month, closer to three. The low-cost safeguard is rhythm, not inventory: order the next cartridge the week the low-toner notice appears, keep printing on the current one, and swap only when output actually fades.

Do scans, copies and incoming faxes all draw on this cartridge?

Scanning uses no toner at all. Black copies and printed faxes do — every sheet the machine puts on paper in black comes out of this cartridge's 12,000-page supply. Offices surprised by fast consumption usually find the copier, not the print queue, doing the heavy lifting.

What makes a page cost about 0.40¢ with this cartridge?

The arithmetic is $48.39 divided by the 12,000-page rating at standard 5% coverage — roughly 0.40¢ of toner per typical office page. Heavy pages such as dense reports and solid graphics use more toner and raise the real figure; light memos and emails use less. Either way, black text on this platform is the cheapest output the machine produces, several times cheaper per page than any of its colors.

Will this cartridge work in our machine?

This is the 841621 black cartridge for Ricoh MP C305SPF — every model on that platform takes this same black, even though the listing names one model in its title. If your machine is on the platform, you have the right cartridge; if it is a different Ricoh altogether, message us with the model name and we will point you to the correct one before you spend anything.

Can I install a cartridge that has sat in the supply closet for a year?

Yes, provided it stayed sealed in its bag, out of heat and direct sunlight — toner does not expire on a calendar the way ink does. Give the cartridge a gentle side-to-side rock before installing to loosen any settled toner, and expect the first few pages to confirm everything is laying down evenly. An opened cartridge that sat out for many months is the one case where weak or patchy early output is plausible.

What does the coverage look like if this cartridge starts streaking after a month?

Streaks, fading or leaks inside the first year are our problem, not yours: the cartridge carries a one-year warranty and a one-year free return window, so a unit that goes bad early gets replaced or refunded. Tell support what the pages look like — Mon–Fri, 9 AM–5 PM CST — and keep the faulty cartridge until we confirm the next step. Full details are on the shipping & returns page.
