Uneven density on the second side of a black halftone image
[Symptom]
Uneven density [a] may appear on the second side of a black halftone image.
The arrow [b] indicates the direction of feeding.
[Cause]
After the first side has passed through the fixing assembly, the paper may have wavy curls [a].
If printing in two-sided mode on the paper sheet with the wavy curls, it allows gaps between the ITB and the sheet during the
secondary transfer, toner scatters in the gaps and results in the aforementioned symptom.
