My Canon iPF6300 imagePROGRAF , which has been a workhouse for the past few years, just died a sudden death few minutes ago. death being defined as : not powering up after a shut down ,>wait> and restart cycle due to a Multi-sensor error message. I have check my AC feed (AC mains > UPS > printer. Both the mains feed and UPS are good)
And what the heck does the multi-sensor do anyway and how do I fix it, if I can get the beast back to running?
