B412dn

The Okidata B412dn is a duplex, network-ready monochrome printer aimed at small workgroups, and it keeps its consumable story unusually simple: one black cartridge family in three capacities. The standard 45807101 is rated at about 3,000 pages, the high-yield 45807105 at about 7,000 pages, and an extra-high option stretches to roughly 12,000 pages for the heaviest users. Every listing on this page is the 7,000-page cartridge, sold as a single and in multi-packs of two, three, five and ten.

On a shared desk cluster, that shape makes sense. Several people print through one B412dn all day, so the cartridge that matters is the one that does not run dry midweek: the 7,000-page yield covers a small workgroup far longer between swaps, and automatic duplexing trims paper use on the reports, invoices and memos that make up most of its workload. Keeping one multi-pack on the shelf means the spare is already in the building when the low-toner warning appears.

Which cartridge should you buy?

Start with how much the printer actually prints. A B412dn serving one or two people at low volume can live on the standard 45807101, but this page stocks the high-yield 45807105 because most workgroups are better served by it: more than double the pages per swap and a lower cost per page. If your group prints every day, buy the cartridge in a multi-pack rather than one at a time — the per-cartridge cost drops as the pack grows, and a five- or ten-pack turns toner into a once-in-a-while purchase instead of a monthly errand. The extra-high 12,000-page tier exists for the busiest desks; match the number on the cartridge you remove if you decide to move up to it.

Chip, toner and everyday use

Each cartridge carries a chip on its side that the B412dn reads when the cover closes, and the printer reports its level from that chip. If a fresh cartridge is not recognized, open the cover, lift the cartridge out and seat it again firmly — a partially seated cartridge is the usual cause. When pages start to fade, rock the cartridge gently from side to side a few times to redistribute the toner inside; that often evens out the remaining supply. Page yields are estimates at 5% page coverage, so dense documents finish a cartridge sooner than the rating suggests. Store spares flat, in their bags, away from heat and bright light until the day they are needed.

Frequently Asked Questions

Which toner cartridges fit the B412dn?

Three capacities fit: the standard 45807101 at about 3,000 pages, the high-yield 45807105 at about 7,000 pages, and an extra-high option at about 12,000 pages. This page sells the 45807105 as a single cartridge and in packs of two, three, five and ten.

My prints look perfect except for one faded corner. What causes that?

A single faded corner usually points to uneven toner distribution or a dirty section of the LED array rather than an empty cartridge. Rock the cartridge gently and clean the LED strip. If the same corner stays faded after a fresh cartridge goes in, the printer itself needs service.

Can I combine duplex printing with toner-save mode?

Yes. Duplexing and toner-save are independent settings on the B412dn, so you can run both at once: two-sided output cuts paper use while toner-save stretches the cartridge on everyday drafts.

Is there any difference between the single cartridge and the 10-pack?

None in the cartridge itself — every pack size holds the same 45807105 unit rated at about 7,000 pages. The packs simply lower the per-cartridge cost and keep spares on hand for a busy shared printer.
