2.5.3.1. ITB Unit overview

The toner on the four drums is moved to the ITB by the first transfer roller (T1 roller).
The image overlapped by four colors is moved to the paper by the second transfer roller (T2 roller). The remaining toners
are removed by the cleaning blade and moved to the waste toner container.
This process is done with one rotation of the ITB. The arrow on the diagram shows the direction of ITB rotation. The
rotation is made by the friction between the drive roller and transfer belt. The tension roller provides tension to prevent slip.
There are three ACR(Auto Color Registration) sensor and one photo sensor. Two of them are for the line position adjustment
and the other is for process control. One photo sensor controls the position of the first transfer roller.
