5.2.4 Photo Conductor small amount rotation control
• Ozone stagnant in areas near the Charge Corona Unit reduces sensitivity of the Photo
Conductors, causing white bands to occur in the image.
• To prevent this image problem, the Photo Conductor is turned so as to allow its surface
facing the Charge Corona Unit to deviate, thereby preventing the surface sensitivity from
being reduced.
A. Photo Conductor small amount rotation timing
• The number of execution sequences is determined when the post process following a
print cycle is completed. The control is executed while the Color PC Drum Motor (M2) or
Intermediate Transport Motor (M3) is in the standby state.
• If the color Photo Conductors need to be turned a small amount during the monochrome
mode, the control is executed also for the color Photo Conductors.
