When Printing on Coated Paper, Stripes Appear near the Leading Edge of the Paper

Remedy
When using paper where the finishing type of the front and back surface differs, change the direction of the paper to improve this situation.
If streaks appear near the leading edge of the paper from the first side in low humidity, the paper may have been curled before loading. Changing the paper to the one that is not curled may improve this situation.
To improve this situation, select the Image Quality Priority for [Switch Fixing Temperature Adjustment Mode].

This function is displayed only if the settings are made available by your local authorized Canon dealer.
