I have a Canon MF6500 Series and received this System Error E197 error while printing a document from Word. I was low on paper in the tray but not out so I refilled the paper tray and turned the printer off for about 30 seconds and it worked fine after that. I guess I'm lucky.

I believe a E197 error refers to a power problem relating to the fuser. I would remove any covers to access the fuser, remove it and reseat it and any nearby connectors.
