Oki MB770dfn Toner Cartridges Printer Review

Expert review of the MB770dfn printer 06 March 2015

Our Verdict:

The heavy-duty Oki MB770dfn A4 mono multifunction printer is quite cheap for its kind. This workhorse features a large touchscreen display for ease of use and is integrated with a large hard drive. The well-connected Oki MB770dfn black and white MFP is ideal for workgroups of 30 or more. It has excellent paper handling capacity that is scalable and even comes with an internal finisher.


The Oki MB770dfn mono laser printer comes with a flatbed scanner on top along with a 100-sheet RADF. Its control panel features a 9-inch colour touchscreen display, function buttons and a numeric keypad. For paper handling, the Oki MB770dfn laser MFP can carry over 600 sheets but with optional trays it can be increased to 3,160 sheets. This model is integrated with 2GB of system memory and a 160GB hard disk drive. The Oki MB-770dfn printer measures 811 x 522 x 564mm and weighs 60kg.


The reliable Oki MB-770dfn mono multifunction laser printer with fax can handle 200,000 pages per month. This robust unit has quick print and copy speeds of 52ppm with the first page out in less than 10 seconds. Scanning speed is also quite quick and can offer a maximum resolution of 600 x 600dpi. For continuous and unattended use, the Oki MB770dfn features a reversing automatic document feeder and a duplexer. For connectivity, workgroups can connect via Ethernet. To ensure security, the Oki MB770dfn all-in-one laser printer has functions such as disable USB host, secure print, storage device encryption, and more. Toner replacement costs for the MB770dfn printer are fairly affordable, especially when users install the more productive Oki 45439002 high capacity black toner.


Although the MB770dfn laser multifunction printer has standard Ethernet, it would be better if Wi-Fi was also built-in and not optional.
