Every spec, no guessing

The M725f is the same 41 ppm B&W enterprise MFP as the M725dn with fax added as a built-in module. If your office still receives faxes — legal pleadings, medical referrals, vendor PO confirmations, insurance authorizations — fax built into the MFP beats a separate fax box that nobody maintains and that's the first thing to break when the phone line gets touched. Same 11x17 capable engine, same scan and copy, same network connectivity. The fax module supports T.30 and T.38 (over IP) depending on configuration. Where buyers regret it: not setting up fax-to-email forwarding from day one. The fax line should drop incoming faxes into someone's inbox automatically as PDFs; if you're walking to the device to pick up paper faxes, you're wasting 2018-era convenience and burning paper on every junk fax. Configure forwarding before deployment and assign someone to monitor the destination inbox. Best for legal, healthcare, and old-school B2B offices that still receive real fax traffic on a daily or weekly basis.
