MB491+LP

The MB491+LP is the printer-only version of the MB491: no copier lid, no scanner — a monochrome printer built for high-volume black-and-white output. It takes the 44574701 black toner cartridge, with the high-yield 44574901 for longer runs, and the 44574301 image drum as its long-life partner. The supply story is deliberately short: two toner sizes, one drum, minimal interruptions.

A print-only machine usually works in a print-only place: the dispatch desk, the warehouse office, the counter where labels, pick lists and invoices come out all day. Nobody there needs a scanner, and nobody has time for a fussy printer. The +LP's value is focus — one job, a deep toner option for long runs, and a drum that stays out of the way for months at a time.

Which cartridge should you buy?

On a high-volume printer the high-yield 44574901 should be your default thinking: long runs punish small cartridges with constant changes, and every change on a working printer is a queue of people waiting. The standard 44574701 remains the right buy where the +LP's volume is only moderate, or as the emergency spare kept beside the machine. Multi-packs earn their shelf space here more than anywhere — a printer this focused should never sit idle for want of a cartridge that costs less than an hour of its downtime.

Chip, toner and everyday use

Keep interruptions minimal by watching two counters, not one: the MB491+LP reports its toner and its drum separately, and the drum's long life means it is easy to forget until quality dips. When a cartridge fades near the end of a long run, rocking it gently side to side redistributes the remaining toner and usually finishes the day's work. Fit replacements promptly and keep the spent cartridge upright in its bag — in a warehouse environment, an open cartridge left lying around collects dust it should never meet.

Frequently Asked Questions

What toner does the MB491+LP use?

The MB491+LP uses the 44574701 black toner cartridge, with the high-yield 44574901 as the longer-running option. Both fit the same slot; the drum is the separate 44574301 unit.

What does the +LP designation mean on this model?

It marks the printer-only configuration of the MB491 platform: the same print engine and the same cartridges as the MB491 multifunction, in a machine dedicated to printing rather than copying and scanning. The toner requirement is unchanged by the suffix.

Does the MB491+LP use the same drum as the MB491?

Yes — the 44574301 image drum serves both. It is a long-life unit changed on its own cycle, far less often than the toner cartridges, and it is the same part whether the machine prints only or also copies.
