Quick view

The Brother MFC-7840W is a multifunction laser printer designed for small office and home office environments. It integrates printing, copying, scanning, and faxing capabilities within a compact footprint. This model offers wireless 802.11b/g connectivity, allowing flexible placement without network cabling constraints. The print engine utilizes monochrome laser technology enabling a maximum resolution of up to 2400 x 600 dpi. The device features a 250-sheet input tray and a 35-sheet automatic document feeder (ADF) for efficient handling of multi-page documents. The scanning component supports color scanning at optical resolutions up to 2400 x 1200 dpi.

The MFC-7840W is equipped with a 32MB standard RAM memory expandable up to 288MB, which aids in faster processing of complex print jobs. The printing speed reaches up to 20 pages per minute for letter-sized paper. Operating with Brother’s proprietary toner cartridges, it balances cost-efficiency and print quality. The device supports various connectivity interfaces including USB 2.0 Hi-Speed, in addition to wireless networking, making it versatile for diverse office setups.

Device control is managed through a 16-character by 2-line LCD panel enabling menu navigation and configuration. The fax component employs ITU-T Group 3 fax standards with a transmission speed of approximately 3 seconds per page. This model runs on standard Brother drivers supporting Windows and Mac OS platforms, facilitating easy integration into existing systems.

The Brother MFC-7840W offers reliable monochrome laser printing with high resolution ensuring sharp text outputs. Wireless connectivity is a major advantage, providing siteless office convenience and reducing cable clutter. Its integration of four functions (print, scan, copy, fax) enables space-saving and efficient workflows. The device’s automatic document feeder enhances productivity for batch scanning and faxing. Strong compatibility with multiple operating systems allows seamless usage across diverse office setups. The relatively fast print speeds and expandable memory support handling of substantial office duties without frequent delays.

As a monochrome-only device, the MFC-7840W lacks color printing and scanning capabilities which limits use cases that require color documents. The input tray capacity, while adequate, may be insufficient for larger volume offices requiring fewer paper reloads. The print resolution of 2400 x 600 dpi is decent but may not meet high-detail graphics demands. The fax modem speed and technology correspond to older standards, which can be slower compared to modern alternatives. Firmware and driver updates are limited due to its discontinued status, potentially affecting compatibility with latest operating systems. The device does not support network printing protocols beyond basic wireless, limiting advanced network management features.
