Transfer Roller Contact
6
The transfer roller [A] is kept away from the transfer belt during the machine ready condition.
When printing starts, the transfer roller contact motor [B] turns the cam shaft [C]. This shaft has two cams
[D] and an actuator [E]. The two cams push the transfer roller contact levers and these push the transfer
roller against the transfer belt. The actuator turns on the transfer roller contact sensor [F] when the cam shaft
turns. Then, the machine detects that the transfer roller touches the transfer belt.
