Paper is fed to the transfer belt before image transfer begins. The paper attraction
roller charges the paper to ensure that the paper is attracted to the belt.
The magenta, cyan, yellow, and black color images transfer to the paper while the
transfer belt feeds the paper past the drums towards the fusing unit. A positive
charge is applied to the paper under the transfer belt, opposite each drum, to
transfer the toner from the drums onto the paper. The back-up roller ensures that
the contact area between the drum and belt is sufficient.
The cleaning unit in the transfer unit cleans the belt surface by applying a charge to
a cleaning roller. The waste toner collected from the belt is transported to the waste
toner bottle.
There are two ID sensors. Only the front one detects the image density of the
patterns generated on the transfer belt for process control. The other function of
the ID sensors is for automatic line position adjustment. Both sensors are used for
this.
