Canon Fax B840 Printer Review

Expert review of the Canon Fax B840 printer 11 December 2012

Our Verdict:

The Canon Fax B840 printer integrates high quality fax, an answering machine, and a telephone in one stylish and affordable device with ample memory capacity. Also aimed at home users, the Canon Fax-B840 bubble jet fax machine boasts a stylish façade and an easy-to-use control panel, but it could have been better with a faster fax modem, higher print resolution, and more fax features.

Design

The Canon Fax B840 fax features a stylish frame with a sheetfed scanner and bubble jet printing technology. It is a standard fax machine with a handset and telephone answering machine, so users can enjoy full telephony features. The Fax-B840 has a 16-character, one-line display screen, an easy-to-use control panel, and a 15-sheet automatic document feeder. The Canon B840 fax machine weighs 3.5Kg and measures 366mm x 265mm x 281mm with the handset and extended trays.

Advantages

Users can fax worry-free even when paper or ink runs out because of the 120-page fax memory. To lower running costs, ink saver mode can be activated in the Canon Fax-B840 inkjet fax. UHQ (ultra high quality) imaging technology and UcanTalk voice recognition dialling are also among the outstanding features of the Canon Fax-B840 inkjet printer. Saving money on the consumables is possible by installing a cheap compatible Canon B840 fax cartridge made from recycled materials.

Disadvantages

The features of the fax machine are limited to auto redialling, verification reports, and activity reports. The Canon B840 fax printer can only record up to 10 minutes worth of voice messages in the answering machine. A larger display screen could serve the Fax B-840 printer better. Transmission speeds are sub-par to newer and faster fax machines because of the 14.4Kbps modem.
