Cause:
A temperature difference occurs on the toner surface between the sides with and without contact
between the transport drive roller and the image. Furthermore, the roller pressure changes the surface
properties of the toner, resulting in a gloss difference.
Occurrence conditions:
• When printing on thick paper equivalent to Paper Weight 8
• When printing on slippery paper
