Miscellaneous Problems

Use only dry paper in the machine. Moisture evaporates from damp paper due to the heat generated inside the fixing unit (it is most likely to occur at low room temperatures). This is not a malfunction, but you can prevent this by using a stack of new unopened paper.
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. Continued use may lead to a fire or electrical shock.

Make sure that the telephone cable is correctly connected. Check to see if the telephone cable is connected to the external device port and the device cable is connected to the telephone line port mistakenly.

See the Starter Guide.

If the machine is turned OFF immediately after changes have been made to the settings from the operation panel or the Remote UI, the changes may not be saved on the machine.

Wait for approximately five seconds after changes have been made to the settings and turn OFF the machine.
