Canon MultiPASS C3500 User Manual page 56

The platen (a roller on the inside of the printer) may become inked
if you print data beyond the width of the page. If this happens, clean
the platen with a soft cloth. (For details on cleaning the platen, see
page 9-4.)
Depending on the density of your printed pages, the ink may need
time to dry. Within two to three seconds, the ink becomes smudge
resistant. After drying for several minutes, the ink becomes water
resistant.
Do not try to load paper into the sheet feeder beyond the paper
limit mark ( ) or the tab on the right side of the sheet feeder;
stacking too much paper may cause paper feeding or printing
problems.
Make sure there are no gaps between the stack of paper and the
paper guide or the right edge of the sheet feeder.
