Product Overview

OKI has recently debuted several new monochrome single-function printers and MFPs intended for offices that don’t require color printing. Among those devices is the B512dn ($499). It prints at up to 47ppm with a first-page-out time of 4.5 seconds. It also has a 100,000-page monthly duty cycle, although OKI recommends a print volume of 750 to 5,000 pages per month.

More details can be found in our Features section below.

The B512dn is an affordable, compact printer that is intended for offices that need to do a lot of printing but not in color. We especially like the environmental features, 1,160-sheet maximum paper capacity, and low total operating costs.


There is a 667MHz processor, 3GB memory, and 2.5GB flash storage memory. PCL, PostScript, PDF, XPS, IBM ProPrinter, and Epson FX are all standard. USB and Gigabit Ethernet is standard. Wi-Fi connectivity is optional. The B512dn also supports mobile printing, such as Google Cloud Print, AirPrint for Apple iOS, and OKI Mobile Print app for Android. There is also the Encrypted Secure Print function.

Paper handling starts with a 530-sheet standard tray and a 100-sheet multi-purpose tray. OKI offers an optional 530-sheet tray ($183.99) for a maximum capacity of 1,160 sheets. Duplexing is standard. Paper output is 150 sheets (face-down).

In addition to duplex printing, the device has strong environmental power saving features, such as Deep Sleep and Quiet Modes, as well as Auto Power Off (unit is shut down after a long period of inactivity).

The B512dn has an excellent cost-per-page figure. There is a choice of a standard (3,000 pages), high-capacity (7,000 pages), or extra-high-capacity (12,000 pages) cartridges. Using the extra-high-capacity (12,000 pages) cartridge, we calculate the cost per page to be 1.4 cents.
