Belt Unit
After passing through the registration unit, paper is electrostatically
fed by the transfer belt through the positively charged feed roll at the
inlet of the belt unit and fed by the running belt. The belt runs at the
same speed as the photosensitive drum causing the image on the
C, M, Y and K developer to transfer to paper.
Since the photosensitive drum has a small diameter and the paper is
electrostatically fed by the transfer belt, the paper is easily
separated, after toner image transfer, and fed to the next developer.
Excess toner is scraped from the drum with a cleaning blade and
recovered into the waste toner bottle.
Adjust the registration when the belt unit is replaced. The
registration is adjusted at the leading edge of the image or by
adjusting the color image. This should be adjusted in maintenance
mode, when the belt unit is replaced.
The transfer belt is conductive and seamless. If the transfer belt is
damaged, toner can cling to the belt and contaminate the paper.
When fingerprints or other stains appear on the belt, wipe them
away with a dry cloth or cloth moistened with alcohol.
A density sensor is positioned facing the belt drive roller for
automatic density adjustment and registration adjustment. A
mechanism is provided to clean the sensor surface, which is
interconnected with the opening and closing of the front cover.
