Canon i-SENSYS MF664Cdw Wireless Colour Laser Multifunction Printer

Not on features — it is a fully capable colour all-in-one. It closes the ranking because it has only two ratings, so there is almost no track record to judge its reliability on, and it is the most expensive machine here at GBP 343. We do not mark a product down for being new; we simply flag that a better-proven colour all-in-one, such as the HP LaserJet Pro 3302fdw above it, is the lower-risk buy.

It is a colour laser, so it feeds four toners — the listing names all eight cartridge SKUs, the standard 067 and high-yield 067H in black, cyan, magenta and yellow. Four cartridges mean a much higher cost per page than a mono machine, which is the trade-off for colour that our whole ranking flags.

It prints, scans and copies in colour, with an automatic document feeder and a flatbed scanner so it handles both single sheets and stacks. It has automatic two-sided printing, a touchscreen, Wi-Fi and scan-to-cloud, printing at 21 pages a minute and up to 1200 dpi.

The listing's model field reads "MF655Cdw" even though the product is sold as the MF664Cdw — most likely a catalogue field carried over from a sibling model. It does not change what you receive, but it is exactly the kind of listing detail this ranking makes a point of reading carefully.

Only if you specifically want Canon colour with the full function set and are comfortable being among the first reviewers. Canon's support network is established, but with two ratings there is little evidence on long-term reliability, and the four-toner running cost is high. For most buyers the better-proven HP colour all-in-one is the safer spend.

It is a substantial desktop machine at 22.6 kg and about 46 x 45.1 x 41.3 cm, holding 251 sheets — the heaviest and one of the largest printers in this ranking, as you would expect from a full colour all-in-one.
