Summary: I have owned the ImageClass MF5770 for almost three years and use it for printing, scanning, and faxing for business purposes on my Vista-based laptop. Here are my impressions based on my experience with my machine: PROs: It still prints, scans, and faxes after three years. The printed documents look fine. The scanning software does what I need it to do for PDF's and JPEG's.
Summary: Things I wish were better with the MF5770: 1.) A seperate tray for Letter and Legal Paper. 2.) The error setting and requirement to change paper if a Legal document is sent to the printer when it is configured for Letter leaving the printer useless until you reconfigure it and change paper. A real pain. The rest of the functions of the MF5770 seem to function as advertized.
Summary: I ordered this printer because I have another one that does not have the network interface. I would have rated this 5 stars due to the ease of use, setup, cost of supplies, and its shear speed. I took two stars away because there is absolutely no mac support nor any plans to add it. This is a great printer but Canon's attitude is costing it a great deal of business. If you have an PC only business than you can't go wrong with this printer.
