Okidata MB491+LP MFP Toner | Compatible 44917601 Cartridges

MB491+LP MFP

The Okidata MB491+LP MFP is the multifunction member of the long-print MB491+ line: it adds scanning, copying and fax to a high-volume monochrome engine, as the counterpart of the printer-only MB491+LP. Its cartridge lineup is deliberately short — the standard 44574701 or the high-yield 44574901 — two black cartridges and nothing else to decide at reorder time.

LP stands for the long-print configuration, built for extended output runs rather than stop-start desk work. Machines in this role tend to live at reception desks and service counters, where output is public, continuous and unforgiving: a visitor does not care why the printer stopped. Everything about running this MFP well reduces to uptime, and uptime is mostly a supplies habit.

Which cartridge should you buy?

For a long-print machine the high-yield 44574901 is the natural working cartridge: extended runs punish small fills, and every changeover in the middle of a queue costs more than the toner it saves. Keep the standard 44574701 as the emergency spare rather than the main supply — its job is to bridge the gap if the working cartridge ends sooner than expected. Buying the high-yield in three- or five-packs turns reordering into a rare, planned event instead of a reaction, which is exactly the rhythm a front-desk machine needs.

Chip, toner and everyday use

Switch on low-toner alerts and act on the first one, not the third — on a reception printer the alert is the schedule. Keep the spare cartridge in the cabinet beside the machine rather than in a central storeroom; a two-minute swap keeps the queue moving, a walk across the building does not. The separate image drum under the toner works on its own long cycle, so a toner change is a toner-only job. And as with every cartridge here, treat printed page ratings as estimates based on standard coverage — long, dense runs consume toner at their own rate.

Frequently Asked Questions

Which toner does the OKI MB491+LP MFP use?

The 44574701 standard black cartridge or the 44574901 high-yield, with a separate image drum beneath them. If the cartridge you remove carries a different number from either, reorder that exact number — the label on the old unit outranks any list.

What does LP mean on the MB491+LP MFP?

LP marks the long-print configuration of the MB491+ family, set up for extended or banner-style output runs. The MFP version adds scanning, copying and fax to that same long-running engine.

This will be our reception printer. How do I keep it ready?

Keep a spare cartridge in the cabinet beside it and enable low-toner alerts. A reception machine cannot wait for a delivery, so the spare-on-hand rule matters more here than anywhere else in the building.

Is the drum replaced together with the toner?

No. The drum is a separate long-life component on this platform and is renewed on its own schedule, long after individual toner cartridges have come and gone.
