Subject:

Measures against white lines in sub scanning direction due to deformation of Primary Fan Duct

Detail:

White lines occur in the sub scanning direction.

<Cause>

A Primary Fan Duct [FL2-3018] is partially warped to the Primary Corona Assembly (to the left) [1]. Then, a Cleaner

Pad stops during its operation to cause white lines in the sub scanning direction.

Add a tap hole to the position a scanner stays in the copier and fix the Primary Fan Duct (FL2-3018) with a screw so

as to prevent it from warping.
