How do the included toner yields compare?
Brother lists the MFC-L3780CDW with starter black toner rated at approximately 2,300 pages and each starter color toner at approximately 1,200 pages. For the MFC-L3720CDW, Brother lists approximately 1,000 pages for each starter cartridge. These are estimated yields, not guaranteed output: Brother says cartridge yield depends on factors such as page size, print coverage, graphics and job characteristics. Brother’s toner-yield guidance
The MFC-L3720CDW brochure identifies TN229-family toner and DR229CL, BU229CL and WT229CL supplies. That does not establish that every listed supply fits both printers. Before ordering, use Brother’s current compatible-supplies listing for the exact model rather than assuming compatibility from a shared family name.

What is established about the MFC-L3780CDW’s paper and document workflow?
Brother describes the MFC-L3780CDW as a color all-in-one for printing, copying, scanning and faxing. Its listing specifies duplex printing, scanning and copying, a 50-sheet ADF and a 250-sheet main tray. The same listing says an optional lower paper tray can bring total capacity to 500 sheets.

The cited MFC-L3720CDW information does not establish a complete side-by-side comparison for fax, duplex scanning, security features or optional paper capacity.
