The Brother MFC-9870 multifunction laser printer includes the same printing, scanning, and faxing features of other models in its line but adds PC faxing capabilities for small or medium offices that want to save time and effort. Optional upgrades make it easy to customize the machine to fit varying needs, and the low cost of Brother MFC-9870 toner keeps operating costs lower than competing models. The optional upgrades allow for flexibility and customization as well. Paper capacity can be upgraded from 250 sheets to a total of 500 sheets by adding an additional tray, and an optional ethernet module can be added to share the machine across a network of users. Standard printer toner for the machine has a page yield of 3,000 pages for a very low cost per page. Using high-yield Brother MFC-9870 toner cartridges will net users up to 6,000 pages, however, making them a better value. Compatible Brother MFC-9870 toner cartridges are also available from many resellers.
