To print on damp paper
The following problems may occur.
Steam is emitted from the machine's output area.
Water droplets form on the back side of the operation panel and in the output area.
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.
