The Brother MFC-8420 looks like a massive pale-gray rectilinear mushroom. The flatbed scanner lies atop the printer body, which serves as its foundation. The machine’s plastic automatic document feeder (ADF) is integrated into the flatbed scanner’s cover. When we closed the lid, we observed that the ADF rattled. The printer’s output tray is located in the center of the machine, immediately below the control panel. The printer’s main input tray is located at the bottom of the machine. Even by multifunction standards, the complete stack is 21.3 inches broad by 17.8 inches deep and 18.8 inches high.The Brother MFC-8420 is an ungainly but endearing multifunction device (MFD) that is top-heavy in terms of both design and price. Home-office users with a large equipment budget may be enticed by its rapid, clear, laser-printed text, but busy small-office workers may be disappointed by the printer’s slow copy speeds and poor scans. Because of the higher consistency of their components, inkjet-based multifunctions are a superior buy. The MFC-8420’s control panel, which protrudes from the machine’s upper front, features a five-line LCD and three buttons labeled Fax, Copy, and Scan. The buttons, which emit a greenish glow when touched, allow you to activate each function independently of the computer; navigation buttons to the right of the LCD allow you to filter through the menus for each function. There are 40 speed-dial buttons to the left of the LCD panel, as well as small clusters of print and fax controls. On the right side, you’ll find copy-specific buttons, as well as a numeric keypad (for dialing numbers the old-fashioned way) and On/Off switches.
