Oki B840n Toner Cartridges Printer Review

Expert review of the Oki B840n printer 11 January 2013

Our Verdict:

A small but busy office can easily produce presentable documents and business correspondence with the versatile Oki B840n monochrome laser printer. The network-ready Oki B840n mono LED printer is compatible with A3 formats and it can easily be shared by a network, though a growing workplace should consider a more affordable printer to purchase and upgrade rather than settling for this device.


The box-shaped yet compact LED technology printer won't take up much space on a desktop because it measures 450mm deep and 485mm wide. The Oki B840n networked laser printer stands 373mm tall and weighs approximately 24Kg, but it may need additional installation space in front because of two paper trays. The Oki B840n printer is integrated with a PowerPC 533MHz processor and runs on 128MB of RAM. Default connectivity includes 10/100-TX Ethernet, high-speed USB 2.0, and parallel ports. The small control panel with a mini display screen allows onboard configuration.


This A4 printer can handle A3 formats, too. The print speeds are up to 40ppm on A4-sized media. The Oki B840n A3 mono LED laser printer only needs up to 19 seconds to warm-up and the first page will be ready in about 5 seconds. A small workgroup can share the Oki B-840n mono laser printer through Ethernet connectivity, and the RAM can be increased to 640MB. Users can get three-year warranty by registering the Oki B840n LED printer upon purchase. The easy to change Oki B840n toner can be installed or removed without any fuss.


There are limited expandability options with the Oki B840n mono printer. The maximum paper capacity cannot exceed 1,690 sheets, and the duplexer is optional. Users might be disappointed with the quality of pictures and the detail in images when printing with the B840n laser printer.
