8.5.31 Feathered image
Fig.8-40
1) Confirmation
This phenomenon may occur when 10 K sheets of paper with a low printing ratio (lower than 3%) are
being printed continuously in the 2-sheet intermittent mode.
When the image shown above appeared, the developer material in the developer unit is probably
decreasing. In this case, pull out the process unit and then take out the drum cleaner unit of the same
color as the image. Then visually check the developer sleeve in the developer unit of the corresponding
color if the layer of the developer material is formed evenly over the roller. If the layer of the developer
material on the area corresponding to the feathered image is thinner than that on the other areas or
totally lacking, replace the developer material.
However, the replacement of the developer material must be performed at the very end. Proceed to “2)
Investigating the cause / taking measures”.
Lack of developer material layer on developer
sleeve (rear side)
The developer material has greatly decreased.
Most of the surface of the mixer shaft is exposed.
