Normally the ITB is in contact with the ITB transfer roller and the drum (there is no motor mechanism to automatically change the position of the ITB).
There are two drum, transfer belt, and PTR separation mechanisms:
- Before the ITB unit is pulled out of the machine, pressure lever [A] must be lowered to separate the drum [B] and the belt [C], and the PTR unit must be removed to prevent scouring of the paper transfer roller.
- When lever [D] is lowered before pulling out the drawer, this separates the PTR from the drum and belt.
