Should you smell something burning, immediately turn OFF the machine, unplug the power plug from the AC power outlet, and contact your local authorized Canon dealer or the Canon help line at 800-652-2666 (800- OK-Canon). Continued use may lead to a fire or electrical shock.
note: - If the machine's power is turned off when there is a paper jam, detection of paper jams in the paper drawers is not possible after the power is turned back on. Clear paper jams without turning the power off.
