Uneven Gloss: Wavy

When duplex printing is performed on paper whose paper thickness level is between 1 and 4, wavy
density fluctuations may occur on side 2.
Cause:
When printing solid fill or other image that consumes lots of toner, the fusing unit temperature rises,
affecting the paper separation from the pressure roller, resulting in glossiness.
• To adjust the following settings, pre-register the type of paper in use as a custom paper. For details
about registering custom papers, see "Registering a Custom Paper", Paper Settings.
Solution:
Carry out the following sequence of procedures. Terminate the sequence as soon as the problem is
resolved.
