Summary: I have had this printer for years and it prints very good BUT there is a major problem with the driver or firmware. If a print job is sent to the printer with the wrong paper (letter size paper in the cartridge and job sent as legal) the printer will fault after printing one page and you cannot clear the printer job from the printer memory.
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: I have only had this unit for 1.5 years. Intermittently, there has been a strange error message (Download Connected/Download Standby), which Canon support says indicates a problem inside the printer that needs to be serviced. I have managed to get the problem fixed to date by unplugging and replugging the power cord, but it is unpredictable as to when it will be fixed. Could be minutes, could be hours.
Summary: We needed a less expensive alternative for church leaders to use in preparing materials to share in their various projects. Took me a little longer to set up than I expected because there is a plastic piece that goes on the back of the machine I couldn't figure out how to install from the directions. It turned out to be vital in holding the paper tray in place so it would stay shut. Once I got that figured out, it has worked well.
Summary: I bought this product just 18 months ago, and it has become completely inoperable on two separate occasions. First, there was an irremediable paper jam for which I had to send the product back to Canon. Then they sent me a replacement printer that broke down for no apparent reason - just decided to freeze one day. Also beware that this product has a strict one-year warranty that does not extend to replacement parts Canon sends.
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: Great Laser printer. Fax works well with good features. Copier with document feeder works very well. Scanner works well, but must use USB cable for scanner - not network capable. All other features are network ready. I am very pleased with my purchase.
