Photo Conductor Small Amount Rotation Control - Konica Minolta BizHub C360 Service Manual

Photo conductor small amount rotation control

• To prevent the same surface of the photo conductor from being left to stand for a long
time, the photo conductor is rotated through a small amount so that its surface sensitivity
can be kept uniform.
• The following image problems can be prevented by letting the photo conductor rotate:
"A difference in sensitivity among different areas of the photo conductor produced as a
result of humidity around the drum unit can cause a black band to occur in the image."
"Ozone that stagnates near the charge corona can reduce sensitivity of the photo con-
ductor, resulting in a white band occurring in the image."
"Nitrogen oxides produced near the charge corona can cause light foggy background to
occur."
A. Start timing
• The control is started under any of the following conditions:
"Upon completion of a print cycle"
"Upon completion of image stabilization control"
"Upon completion of the TCR automatic adjustment operation"
"Upon completion of the auxiliary toner replenishing operation"
"Upon completion of predrive performed when the power is turned ON (only if an image
stabilization sequence does not follow)"
