Adjusting the Image Clear Level of the ITB (Intermediate Transfer Belt)

When automatic cleaning is not sufficient to remove the toner residue on the transfer belt, toner residue may transfer to the paper, and this could adversely affect the quality of the image. In this case, adjust the image clear level of the ITB for the custom paper type.

This function is displayed only if the settings are made available by your local authorized Canon dealer.
