Vertical White Streak Roller Marks

When duplex printing of halftone images is performed, roller marks may appear as vertical white streaks
on Side 1.
This is prone to occur when textured media is used.

Cause:
This is caused by the main relay roller.
When duplex printing is performed, the nip of the main relay roller 1 [A] becomes separated when
shifting for horizontal registration on Side 2. During that, the drive roller (circled in blue in the figure)
stops rotating at the position protruding on the paper guide's side, resulting in Side 1 of the paper
coming into contact with the drive roller and creating roller marks as vertical white streaks.
