This is my 2nd MFC-L5700DW for my office. It does everything our Ricoh copier does.
2 sided printing, toner saver, scans and faxes. The only downside is the scanned copies are a bit larger in size (KB); but definitely is do-able. Toner costs are cheap too ! I found the best deal at Sam's which surprised me. I usually buy from an East coast electronics company.
