Additional Information
You have to remove a fair amount of orange protective tape and foam inserts (as is typical with any printer). Basic set up was pretty straight forward- plug in the power cord and connect via CAT5 or USB or via Wi-Fi. I did the CAT5 and my computer immediately located the new printer and was able to print. The black and white was crisp and the colors clean on regular laser multi-purpose paper.
The printer does not come with a manual, and unfortunately it is hard to locate the proper manual from Canon. As a matter of fact, when you put in the MF644Cdw to search for a manual, the first unit that comes up on the Canon site is their MF733Cdw.
Fortunately, the help screen on the printer guides you through most necessary set up and use steps. However, if you want to use it as a scanner, you need to go to the Canon site and download both a new driver and their scanner application. Again, be careful to select the MF644 and not the MF733, because it is a different driver.
Once you download the new driver and scanner application, that works very well from either your computer or the lcd screen on the printer.
The printer comes with an additional plastic piece that turns out to be the legal paper size dust cover. You won't find any explanation of this piece with the printer, nor in an on-line manual (if you can find the correct one). I found the answer on a Canon users blog. It is for use when you extend the paper cassette tray to load legal size paper. You then can insert the 'dust cover' into the tray and re-close the tray.
The unit is 16.9" x 16.5" x 16.5" (429 mm x 419 mm x 419 mm) and weighs 48.4 lb. (22.0 kg). It comes with 'starter' toner already installed. Replacement OEM toner $70 to $95 for the black and colors each. There are a number of non OEM toners advertised at about 1/4 the price. I will do an update after several months of use. - JTech
