If you change the setting to simplex (for one-sided printing), the rating jumps to 26 ppm. Speed and Output Quality By default, the MF4880dw driver is set for duplex printing, which means its default speed rating is also for duplex mode, at 16 pages per minute (ppm). For my tests I connected it to a network using the Ethernet port and installed the drivers on a Windows Vista system. At roughly 14.2 by 15.4 by 17.0 inches (HWD), the MF4880dw is a little large to share a desk with, but small enough so it shouldn't be hard to find space for, even in a small office. If you need more, however, note that there aren't any options available to add more capacity. Together with the duplexer, this should be enough for most micro or small offices and more than enough for most personal use. Paper capacity for printing is limited to one 250-sheet tray plus a manual feed, so you can print on different paper stock without having to swap out the paper in the tray.
For scanning, it offers both a letter-size flatbed and a 35-page automatic document feeder (ADF), which can scan up to legal-size pages.
