When you remove the transfer cleaner drive
assembly, the ITB cleaning blade [1] is likely to come
into contact with the intermediate transfer belt by the
work of a spring, causing toner [2] to deposit on the
belt surface in the form of lines. The toner can then be
forced against the photosensitive drum by the primary
transfer assembly, thus affecting the photosensitive
drum cleaning blade [3].
