Oki B840dn Toner Cartridges Printer Review

Expert review of the Oki B840dn printer 11 January 2013

Our Verdict:

The Oki B840dn is a compact digital LED printer designed for small offices and home users with basic document printing needs. Flexible media handling, network-friendly interface, and high-end security are among the notable features of the Oki B840dn duplex, networked printer but users might be disappointed with the graphics and the limited expandability options.


The Oki B840dn mono laser printer measures 373mm tall and 485mm wide, but it can be up to 575mm deep from 521mm when the paper trays are extended, so it needs additional installation space at the front. The B840dn laser printer weighs approximately 28Kg, runs on 128MB of RAM, and comes with a built-in LCD display on the minimalist control panel. The main connection ports include parallel, high-speed USB 2.0, and Ethernet. The capacity of the black Oki B840dn toner cartridge is approximately 20,000 pages.


LED laser technology makes the Oki B840dn printer more cost-efficient to run and faster to print, at up to 40ppm on A4-sized media. It takes 19 seconds for the printer to warm-up and the first page is ready in five seconds. The Oki B840dn laser printer has built-in Ethernet and two-sided printing functions, and it supports commonly used printer languages and network protocols. Text output looks fine and sharp in either 1200x1200dpi or 600x600dpi. An optional 16GB memory card can be integrated into the Oki B840dn mono LED printer, or users may increase the memory to 640MB.


A growing office should look elsewhere because the maximum paper capacity of the Oki B-840dn mono printer cannot exceed 1,690 sheets. Print quality declines on complicated graphics and pictures. The high initial cost and weight are the other setbacks of the B840dn workgroup printer. The B840dn deserves a tiltable display screen for a more comfortable view.
