Toner accumulates on the edge of the ITB cleaning
blade. Turning the ITB clutch Off/On forces accumulated
toner on the blade edge to drop on the ITB while there is
no image on the ITB, and then this toner can be
removed. If this is not done, toner may drop on the
image. These SPs adjust the time and number of times
for blade cleaning.
