9 matching models from 48 checkedBest for this need
Our pick

The Canon MF462dw II is a strong starting point for monochrome office work because its 50-sheet feeder scans both sides in one pass. Choose the MF665Cdw when color output matters, or the Brother MFC-L5915DW for larger scan stacks and heavier printing.
Choose a printer that scans both sides automatically. Compare color needs, scan-stack size and the difference between duplex printing and duplex scanning.

What matters in practice
Start with the number of sheets in the incoming packet and whether printed output needs color.
A 30-sheet two-sided contract contains 60 faces. A single-pass duplex feeder captures those faces without asking you to turn the stack for the backs. Feeder capacity is normally expressed in sheets, so 30 suitable sheets fit in a 50-sheet feeder even though the file contains 60 scanned faces.
The Brother DCP-L2640DW and Canon MF751Cdw II print on both sides automatically, but their feeders scan one side at a time. They can still be useful for one-sided originals. They are weaker fits when avoiding manual reversal is the reason for buying a new machine.
A document feeder is for supported loose sheets. Keep a flatbed for bound books, delicate originals and items outside the feeder’s paper limits. Single-pass scanning does not automate turning book pages.
The Brother MFC-L5915DW accepts 70 sheets and is recommended for up to 8,000 printed pages a month. The Canon MF462dw II accepts 50 sheets and recommends up to 4,000 printed pages. A 60-sheet packet or a regular 5,000-page month gives a concrete reason to step up to Brother.
