The toner is moved from the four drums to the ITB by the four image transfer rollers. This is
done with one rotation of the ITB (four toner images are super-imposed onto the belt). The
arrow above the C and M drums on the diagram shows the direction of ITB rotation.
The ITB drive roller then moves the four-color toner image from the transfer belt to the
paper. The paper transfer roller is an idle roller.
The cleaning unit in the transfer unit cleans the belt surface with the cleaning blade and
roller. The used toner collected from the belt is transported to the toner collection bottle.
There are seven ID sensors. Three of them are for the line position adjustment. Four of
them are for process control.
