The Samsung SF-5100 is also referred to as the SF-5100P or SF-5100PI. It has a good blend of faxing features. Its transmission speed is a bit slow, at only 14.4 kbps, but for the average user, this will likely be fast enough for light-duty use. Faxes and copies print at around 6 pages per minute. The 20-sheet automatic document feeder accepts pages for both faxing and copying, but copying is somewhat limited without a flatbed scanning surface, so scanning larger media like books is out of the question. Copies can be reduced and enlarged from 30% to 150%, and up to 99 copies can be made at once.
