effect is not generated between the paper fiber and the toner. Consequently, the toner is
separated from the paper and attaches to the fusing belt.
(d) Static electricity noise
When the paper is discharged too much, the electrostatic absorption power between paper
and toner is reduced. When the image enters to the fusing nip, it gets effect of the electric
field and scatters the image, causing darker density.
(e) Trailing edge noise
Paper charging amount at the trailing edge is high on of the thick paper. This potential
remains on the fusing belt and affects the next image. (Color lines if toner is scattered or
white line if toner is separated)
(3) Solution
1. Check the fusing heat roller ground
Check the conduction between fusing heat roller and fusing unit frame using the tester.
See the photo below.
There should be electricity conduction (less than several hundreds Ω)
Should contact with tip
(side) of roller's core metal
