Cause:

Due to the leading edge of the paper being curled or wavy directly after fusing, an angled force is applied to the paper until the trailing edge of the paper moves out of the fusing unit, producing oblique creases.

This may occur if:

  • The thickness of the paper is equivalent to Paper Weight 3 or lower

  • Paper smaller than A4Portrait is used

  • Printing solid fills

  • Duplex printing

Note

  • To adjust the following settings, pre-register the type of paper in use as a custom paper. For details about registering custom papers, see "Specifying a Custom Paper", Preparation.
