B440

The Okidata B440 is a monochrome laser printer from OKI's B400 series, designed for workgroups that need dependable high-volume black-and-white output. It takes the same black toner family as the B410 and B430: the 43979101 at 3,500 pages, the 43979201 at 7,000 pages and the 43979206 at 12,000 pages, so an office can scale capacity with demand. Imaging is handled by a separate drum unit, the 43979001, which lasts roughly 25,000 pages — well beyond a single toner cycle. The listings on this page stock the standard 43979101 cartridge and the drum.

Three yields for one printer is a planning tool. A workgroup rarely knows its true monthly volume when a printer is installed, and the B440's family lets the supply order learn: start on the standard cartridge, watch how long it lasts, and step up a tier when the pattern is clear. Because the B410 and B430 drink from the same family, mixed fleets of these machines still stock one shelf of cartridges.

Toner Cartridges for B440

Toner is only half the consumable picture on the B440. The drum unit below images every page and is replaced on its own, much longer cycle:

• 43979001 Drum Unit — Black — roughly 25,000 pages
• 43979001 Drum Unit (listed for B410)
• 43979001 Drum Unit — 2-pack
• 43979001 Drum Unit — 3-pack
• 43979001 Drum Unit — 5-pack
• 43979001 Drum Unit — 10-pack

Which cartridge should you buy?

Cost per page falls as yield rises, so the honest answer depends on volume. The 43979101 at 3,500 pages — the cartridge stocked on this page, singly and in multi-packs — suits lighter or intermittent workgroup use and keeps the purchase small. The 43979201 at 7,000 pages is the middle step for a printer in daily service. The extra-high-yield 43979206 at 12,000 pages gives the lowest cost per page of the three and is the economical pick for steady daily printing. Any of the three can be installed next, whatever the printer ran before. Separately, budget the 43979001 drum as an occasional purchase: at roughly 25,000 pages it comes due long after most toner orders.

Chip, toner and everyday use

All three yield tiers share one fit and one chip arrangement, so the B440 reads whichever cartridge you install and reports its level without any setup. That makes tier-switching a buying decision, not a technical one. Remember that the printed yield figures are measured at about 5% page coverage — a workgroup printing dense text documents will land close to them, while graphics-heavy pages finish cartridges sooner. When output fades evenly across the page, toner is the first suspect; when quality stays poor through a fresh cartridge, look to the drum, which ages on its own count toward roughly 25,000 pages.

Frequently Asked Questions

What toner does the Oki B440 use?

Three black cartridges fit: the 43979101 (standard, 3,500 pages), the 43979201 (high-yield, 7,000 pages) and the 43979206 (extra-high-yield, 12,000 pages). A separate drum unit, the 43979001, handles imaging.

Which B440 toner gives the lowest cost per page?

The extra-high-yield 43979206. Cost per page falls as cartridge yield rises, so it is the economical pick for steady daily printing, while the 43979101 suits light or intermittent use.

Can I switch from the standard 43979101 to the 43979206 mid-life?

Absolutely — the B440 takes whichever of the three cartridges you install next. Many offices start with the 43979101 and move up once they can see their real monthly volume.

When does the drum need changing?

The 43979001 drum is rated at roughly 25,000 pages, so it outlasts several toner cartridges. Change it when print quality problems persist even with a fresh toner cartridge installed.
