Symptom

In high humidity environment, dark vertical line under 5mm in width [a] may appear on halftone image. [b] is the feeding direction.

Cause

Wax component contained in toner may attach to drum when pressed by drum cleaning blade.

When moisture gets on the area where wax is attached in high humidity environment, less amount of electricity is charged in such area. The above-mentioned symp-

tom occurs due to the difference in the amount of electricity charged between the areas where wax is attached and where it is not attached.
