Our pick

The Canon MF665Cdw is a useful starting point for color handouts and two-sided document stacks. Choose the Brother MFC-L3780CDW for a 30-sheet multipurpose tray and higher rated color speed, or the Canon MF662Cdw when copying is limited to books and individual sheets.
Choose a color laser-class printer around incoming documents, double-sided scanning and paper handling, with alternatives for books and longer print batches.

What matters in practice
Pick the scanner for incoming originals and the paper trays for outgoing jobs.
The MF662Cdw and MF665Cdw both have a 26-ppm rated Letter print speed. The MF662Cdw has only a flatbed, while the MF665Cdw adds a 50-sheet single-pass duplex feeder. A stack of two-sided forms therefore makes the MF665Cdw a much more convenient fit despite similar printing headlines.
Canon’s single-sheet feed is sufficient for occasional supported special sheets. Brother’s MFC-L3780CDW supplies a 30-sheet multipurpose tray, which reduces repeated loading during short batches on alternate stock. Check the tray’s media limits rather than assuming every label or envelope can use its full capacity.
Both Canon models have a flatbed. If nearly every original is bound or a single card, the MF662Cdw keeps that ability without paying for a feeder that cannot turn book pages. Choose the feeder when loose multipage documents are a recurring job.
Color charts and mostly black text consume different amounts of toner. Standardized cartridge yields provide a comparison basis, but they do not establish a monthly bill without current prices and an assumed document mix. Include separate maintenance supplies where the manufacturer specifies them.
