Expert review by: M. David Stone (



The OKI MB491+LP multifunction printer offers a legal-size flatbed and a duplexing automatic document feeder for scanning and copying.

Prints, copies, scans, faxes. 50-page duplexing (two-sided) automatic document feeder. Duplex printing. Legal-size flatbed.

Although fast enough so speed isn't an issue, it's a little slow for the price and rated engine speed.

The OKI MB491 monochrome laser MFP is designed for micro and small offices with relatively heavy-duty print needs.

Prints, scans, copies, faxes. 50-page automatic document feeder. Duplex (two-sided) printing.

Although not slow enough for speed to be an issue, it's a little slow for the price and rated engine speed.

Uffda Mama, this one is difficult!


It's still working; sort of. Compared to the Brother MFC-8710dw that I love, it hasn't broken yet.

So, I've had this printer for a few months now and complain about it every day for one reason or another. I absolutely loved my Brother MFC-8710dw, but had two break in one year. (I still have one in our front office, and hoping it lasts awhile.) I am...

Should have been clearly marked as having no wireless networking capabilities. It is misleading not to make it clear on such a high-tech printer.

Great device. It is one of the best printers I have ever owned as of this moment. I am in law school, and I print high quantities of various document/cases on a regular basis and this print speed/scanning is top notch and beats anything I have ever owned.

Does not have a wireless card and cannot achieve network connectivity without a wireless-card or external wireless print server. I would assume that a piece of equipment this advanced with its vast multitasking capabilities would have wireless...

Updated description


Reasonably economical on toner usage. Good workhorse for small to medium sized business environments.

Runs all day every day. Good quality print.

Newegg updated the description to now say "Monochrome" printer. They originally called it a "Color" printer. It does fax and scan in color, if that helps. If the power goes out, beware that when the printer comes back on, the TCP/IP address might have...

Good -BUT!!


MY bad. I didn't read the description page closely enough, and what I thought was supposed to be a workgroup COLOR LASER PRINTER, turns out to be only a MONO LASER PRINTER. It works just as advertised, but maybe NEWEGG should not label it as a "42 ppm...

Fast, good quality print, does it all

Be careful - this printer only PRINTS IN MONO (Black & White). It Scans and Faxes in color. Took off one EGG because of it not doing what I expected. Not really the products fault, but as you will notice it is advertised as a "Color Laser Printer"...
