Summary: Purchased this printer in December 2006 from Amazon, primarily for duplex capability. Have printed thousands of pages and scanned hundreds. Still functions great. As OEM cartridges are $150, I've relied on after market products.
Summary: This product has a known defect that the company is keeping quiet. The defect is the "laser shutter" a little bracket that apparently is not strong enough to do its job. Repair people say they are getting many calls on this "known problem.
Summary: This printer could be great with a little bit more attention from Canon. I won't repeat the details from the other reviews, but here's a summary of what I like about the printer and the problems I've had. 1) The paper capacity is good.
Summary: I purchased the Canon MF6550 to replace a Canon PC980 copier, and to replace an HP 6210 All-In-One which my office used as a FAX. I was slightly worried because the reviews here were only lukewarm, but on other sites they were better.
Mixed feelings about what should have been a great item

Summary: I'm sure I don't yet have a complete grasp of this machine, but that fact itself, given that it is far from my first multifunction office machine OR my first laser, and I've had it for a couple of months, shows that perhaps it's not as easy to get used to as it could be.
Summary: Looks like Canon has enough money, or hasn't read sales statistics over the last few years. They do not provide drivers for the scanner portion of this unit for Macs, nor will it work, they claim, over a network.
Summary: My office has used this printer for four months now. It isn't very user friendly----it seems to require extra time to get things done, but the printing, faxing, and copying are good. My big complaint is the cost of toner replacement. I'm used to paying about $5/month for toner usage.
