Transfer belt contact
The transfer belt does not touch the color PCUs (cyan, magenta and yellow) when
the machine makes a black and white print.
The transfer belt contact motor [A] turns the CMY contact cam shaft [B] when the
machine starts to make a color print. The CMY contact cam lifts the belt transfer
roller unit for CMY [C] to the transfer belt. Because of this mechanism, the life of
the transfer belt is longer (it is not necessary for the transfer belt to touch the color
PCUs when the machine makes a black and white print).
The transfer belt contact sensor [D] detects if the transfer roller unit for CMY
touches the transfer belt. If it does not touch the transfer belt during color printing,
the machine stops and shows SC 442.
