Conclusion: The Canon imageClass MF5550 is a personal all-in-one with a built-in fax modem and 50-sheet automatic document feeder. It lacks some conveniences—notably a driver to fax from any program—but it will serve as a copier, fax machine, scanner, and monochrome laser printer with good to excellent output quality.
Pros: Excellent text quality. Good graphics and photo quality. Built-in fax mode and 50-sheet automatic document feeder. Good performance.
Cons: Copies only from front panel. No fax printer driver. The only way to fax from a PC is via the drag-and-drop feature in Presto! PageManager.
