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. This is hit and miss, as some manufacturers have good products, other poor. The printer is quietest with Canon OEM cartridges. However, when one OEM cartridge is as expensive as 5-6 after market products, the noise is not an issue.
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." In fact they say they know what is wrong when they get the call for a won't print repair.
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. It lets you put a full ream of paper in the tray at once, and you can still use the side "multi-purpose tray" for printing on special paper such as labels. 2) The scanner/copier glass is bigger than most other printers.
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. Well, let me just say whoever is complaining about this machine is way off base. First, it came with a Windows VISTA disc so it worked seemlessly with my VISTA computer. Second, it is nearly twice as fast as the PC980 (23 pages vs. 12).
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. I love the auto duplexing, the large scanning bed, and the speed of printing. I like the way it goes to sleep between jobs and wakes up so quickly.
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. This is a decision made at corporate headquarters in Japan, and the locals at Canon USA are apologetic but powerless.
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. Since we bought the Canon four months ago, we've been through the starter toner and two new toners ($140 each). I figure I'm paying $90/month for 1,000 copies (or less).
