The scanner uses a flatbed setup with a resolution up to 600 x 2400 dpi for detailed image capture. The device's memory allows for fax storage and efficient operation with varied document sizes. It supports standard connectivity options including USB 2.0 alongside wireless, catering to different user setups. The MFC-7840W runs on Brother's embedded firmware optimized for reliability in mixed office environments.

Drivers and software are compatible with major Windows and Mac OS versions from the period, facilitating ease of integration. The multifunctional design helps to minimize desktop clutter while offering essential office functions in one device. Its relatively low power consumption during operation and ready modes makes it an economical choice for regular office printing needs.

The Brother MFC-7840W offers versatile multifunction capabilities including print, copy, scan, and fax within a single compact device. Wireless networking allows multiple users to share the printer without physical cables, enhancing office flexibility. A high print speed of up to 20 ppm improves workflow efficiency for higher volume jobs. Its 250-sheet standard paper capacity reduces the need for frequent paper refills during large print tasks. The inclusion of an automatic document feeder facilitates easy handling of multi-page documents for faxing or copying. Furthermore, compatibility with various operating systems ensures broad usability and simple installation.

The Brother MFC-7840W is limited to monochrome printing and does not support color output, which restricts it for users requiring color documents. Its print resolution, while sufficient for text documents, may not meet the quality demands for high-resolution photo printing. The device's fax modem speed, capped at 33.6 Kbps, is considered slow by modern standards. The scanner, though capable, is a flatbed type without duplex scanning capability, limiting efficiency on double-sided documents. Memory capacity is modest, which may constrain fax storage and complex print job management. Also, as a product from 2008, driver updates and software support for newer operating systems could be limited or unavailable.
