Re: Canon imageCLASS MF5770

Download connected is a sign that it has some how got into a firmware update mode. If reseting the unit with all cables (USB and Phone) disconnected for about 2 hours doesn't resolve the issue it will require servicing

I have the same problem. You can't use Canon Toolbox 4.9x. It does not work. You will have to download and intall the x64 driver only from the Canon website for the MF5770.

Unpack the x64 driver and install it.

Go to the Start-menu and click on Units and Printers. Right-click with your mouse when hovering over the printer, then choose scan, fax or print.

We can only hope that Canon will solve the problem in the future, most likely not since MF5770 is an older Multifunction-machine.

Paper feed broken

You broke a part. It is a low end machine. The repair will cost close to the repalcement cost of the machine. I would replace it and start with a new warranty.

Finally fixed it myself. I ended up having to take the auto document feeder apart with a screwdriver and put this tiny plastic piece back onto its little cradle thingy. Working great now!
