White spots/white streaks on image due to lubricant attached
[Symptom]
White spots [a] or white streaks [b] may be generated.
The arrow [c] indicates the direction of feeding.
[Cause]
Lubricant is applied to the bushings of some rollers/gears to prevent their abrasion.
If the lubricant applied is attached to a part such as the feed guides [a] within the area between the paper pickup assembly and
the secondary transfer assembly, the lubricant would be scraped off with the leading edge of paper when paper is passed through
and would move onto the ITB in the secondary transfer assembly.
It becomes hard to transfer toner onto paper at the spots where carries lubricant on the surface of the ITB, hence the
aforementioned symptom occurs.
