Our Verdict

Epson EcoTank ET-3950

Canon Color imageCLASS MF665Cdw

The Epson EcoTank ET-3950 and the Canon Color imageCLASS MF665Cdw target a similar market but differ in their strengths. Both come with fully featured scanners that include automatic document feeders, duplex scanning, and fax capabilities. The Epson is cheaper and it stands out for its low long-term cost per print. Its high-yield, SuperTank cartridges are very cheap to refill. It's also a solid choice for photo printing, unlike the Canon, which relies on laser technology not intended for that purpose. The Canon, on the other hand, is faster and better suited for time-sensitive workloads. It also doesn't clog if left unused for a certain period, unlike inkjet printers. It also produces more detailed scans and printed documents. Overall, while they target a similar market, each printer excels in different areas.
