Frequently Asked Questions
What toner does the Oki MB491 Plus use?
The MB491 Plus uses black toner: the standard 44574701, the high-yield 44574901, and the 44917601 cartridge also listed for this model. Check which cartridge is currently installed before reordering, since this model accepts more than one black toner part number.
Which black toner should I choose for the MB491 Plus?
For heavy printing, copying and faxing, pick the highest-yield option available for your slot — it lowers the cost per page. For light use, the standard 44574701 is fine. The key rule is matching the part number to what is already in the machine: 44574701, 44574901 or 44917601.
Does the MB491 Plus use toner when receiving faxes overnight?
Yes — incoming faxes print automatically and consume black toner just like any print job. If the machine receives many faxes, a high-yield cartridge (44574901 or 44917601) lasts far longer; enabling junk-fax blocking also saves toner.
