The 420cn's scans turned out only fair. Black-and-white scans looked so faint that light areas of the test document disappeared completely, and fine areas of the gradient appeared fuzzy and indistinct. The printer's color scans were also pale, faint, and overexposed. In scanning speed, the Brother averaged some 3ppm for both color and grayscale documents, about average, as was its 2.3ppm photocopying speed.
This model worked well throughout the testing process. CNET Labs tested the unit at the default manufacturer settings, which can be adjusted to better the performance.

Performance analysis written by CNET Labs project leader Dong Van Ngo.Installing the Brother MFC-420cn is a simple matter of plugging it in and connecting it to your computer via a USB cable. To access the USB 2.0 port, you'll have to lift the top cover, thread the cable into its port, then replace the cover. The Brother MFC-420cn comes with plenty of documentation, including a printed user guide. The lengthy printed booklet covers setting up the 420cn for faxes, copies, prints, and media-card reader use. For detailed information about connecting the 420cn to a network, using the software, and scanning, you'll have to consult the CD-ROM manual. Brother also provides both digital and print quick-setup guides to lead you through the simple installation.
