MB290 MFP

The Okidata MB290 MFP is a mono laser multifunction machine for small offices, packing printing, scanning, copying and faxing into one compact box. It shares its toner family with the MB260MFP: the standard 56123401 and the high-yield 56123402, with this page stocking the high-yield cartridge as a single, a 5-pack and under the MB290 MFP name.

Machines like this often anchor the corner of an office where faxes still arrive and forms still get copied. Everything it prints — documents from the computer, copies off the glass, fax pages rolling in — draws on that single black cartridge, which makes the cartridge's remaining level the one number worth watching.

Which cartridge should you buy?

Match the number on your current cartridge when you reorder — that habit settles most of the question. Between the two family sizes, the high-yield 56123402 listed here is the better fit for an office machine that copies and receives faxes daily: more pages before the next change, and a lower cost per page across its life. The standard cartridge remains a reasonable choice for a lightly used machine. If the MB290 is the office's only printer, the 5-pack is worth considering purely so the spare is already in the building when the current cartridge fades.

Chip, toner and everyday use

The printer follows the cartridge's chip to estimate what remains, but fax traffic can mislead your own sense of it — received pages print whether or not anyone is watching the queue. When output starts to look thin, a gentle side-to-side shake of the cartridge redistributes the toner for a short reprieve. Store spares sealed and flat, away from sunlight, and remember that only printing consumes toner: scanning and sending faxes leave the cartridge untouched, while every received fax page spends a little of it.

Frequently Asked Questions

Which toner fits the Okidata MB290 MFP?

The 56123401 standard cartridge, or the 56123402 high-yield cartridge stocked here. Match the number on your current cartridge when reordering.

My MB290 MFP fax confirmations print faded. Is that a toner issue?

Usually, yes — faded confirmation pages mean the toner is running low. Since only printing consumes toner, a steady diet of fax reports and received pages drains the cartridge over time even if nobody prints from a computer.

Can the MB290 MFP copy in color?

No. This is a monochrome MFP, so copies print in black and white using the single toner cartridge. Color originals still copy — they simply come out as grayscale.
