Black Streaks
Short black streaks appear on a black halftone image.
Cause:
A sheet is bent at the entrance to the fusing unit and comes into contact with the edge of the paper
delivery tank, where static electricity builds up on the sheet through friction. This causes scattering of
unfixed toner on the paper surface.
This may occur if:
