The System Manager PIN for a MF726Cdw unit was not entered correctly, and the technician cannot recall what was typed instead. Is it possible to factory reset one of these series multi-function printers?

I spent a good amount of time searching for this solution as well because I'm in the exact situation as you. I wasn't able to find anything helpful so ended up calling Canon support. To factory reset a Canon ImageClass MF726Cdw, do the following:
- Press and hold number "4" button
- While holding the button, turn off the printer using the power switch, do not let go of the button
- Continue holding it while switching the power back on until it completely boots and is at the menu screen.
Hope that helps
