The new OKI B840 A3 mono printer has the speed, versatility and footprint of an A4 only device and yet can print on A3 as well as A4 sized media. The compact design of the B840 allows it to be positioned close to the workgroup and provides fast print speeds of up to 40ppm A4 and 22ppm A3.

There are three variants of the OKI B840 printer: the B840n which is network ready and has a single paper tray; the B840dn which adds duplex; the B840dtn which comes with two paper trays as standard.

The OKI B840 has PCL/PostScript built-in for maximum platform flexibility and application support and has a 533Mhz processor with 128MB standard RAM (upgradeable to 640MB) for fast processing of large print jobs. A 16GB SDHC memory card option provides a ‘Secure Print’ function that ensures confidential documents remain that way by encrypting data as it travels across the network and requiring a PIN code to retrieve the document.

Standard paper capacity is 530 sheets plus a 100 sheet multipurpose tray. Maximum capacity is 1,690 sheets from 4 paper sources (when fitted with 2 x 530 sheet additional tray). Media weight handling is up to 200gsm from the multipurpose tray and up to 176gsm from all other trays. Duplex is optional on the B840n and standard on the B840dn and B840dtn.

An easy-to-change, single piece high capacity print cartridge delivers up to 20,000 A4 pages to ensure maximum uptime with minimum user intervention.

Recognising that printers spend more time not doing anything than actually printing the OKI B840 comes with a deep sleep mode that consumes less than 1.2watts and that will save energy and reduce C02 emissions at the same time.
