OKI B840dtn Printer Review

Expert review of the OKI B840dtn printer

Our Verdict:

Aimed at small workgroups, the Oki B840dtn A3 mono duplex network laser printer with second tray offers versatile media handling and expandability options. It uses Oki's digital LED technology, with the option to print on A3-sized formats for bigger and more presentable documents, but while it is affordable to run, users may find the Oki B840dtn printer expensive to purchase and lacking some important features.

Design

Unlike its siblings, the Oki B840dtn A3 mono laser printer is larger and may take up more space on a standard desktop because it measures 575mm deep, 485mm wide, and 520mm tall, and weighs approximately 35Kg. The B840dtn A3 LED laser printer runs on 128MB of RAM and a 533MHz processor, with room for an optional 16GB SDHC memory card. The box-shaped unit connects to a computer via high-speed USB 2.0 or a parallel port, and to a network via 10/100-TX Ethernet. Default paper handling includes a 100-sheet multi-purpose tray, a 530-sheet input tray, and 100-sheet face-up and 250-sheet facedown output bins. A small display screen is part of a control panel with one-touch operational functions.

Advantages

Oki offers a three-year warranty for this device. The print speeds are up to 40ppm on A4 media and 22ppm on A3 paper. The Oki B840dtn mono laser printer can easily be shared by a workgroup via Ethernet, and it supports a wide range of network protocols. Text documents, line art, and graphs are printed well in 1200x1200dpi. Two-sided printing is a standard feature in the Oki B840dtn LED printer. Minimum effort is required in maintaining the machine which simply uses a single black Oki B840dtn laser toner cartridge to print up to 20,000 pages of black and white documents.

Disadvantages

Very complicated graphics and high quality images may lose some of their details when printed using the Oki B840dtn workgroup printer because it can only produce output in monochrome. The device doesn't offer further expansion options for the paper capacity beyond 1,690 sheets. The B-840dtn is also criticised for the high initial cost, and users may need to spend more if they want to upgrade the input capacity and memory.
