ITB cleaning control
This controls the removal of the residual toner from the ITB to prevent an image defect.
The following is the sequence of this control.
1. The cleaning blade on the ITB is always in contact with the ITB and scraping the
residual toner off the ITB. (See callout A in figure
Figure 5-45. ITB cleaning control,
below.)
2. The toner scraped off the ITB is transferred onto the waste toner conveyor belt by the
ITB cleaning screw.
3. The waste toner is delivered to the waste toner container, sitting inside the ribs of the
conveyor during transfer. (See callouts B and C in figure
Figure 5-45. ITB cleaning
control, below.)
