1 | PTR Roller |
2 | PTR Idle Roller |
| 3 | PTR Unit |
4 | Actuator |
5 | PTR Lift Sensor |
6 | Cams (front and rear) |
7 | PTR Separation Motor |
The PTR separation motor in the ITB unit raises and lowers the PTR roller to open and close the nip between the PTR roller and the PTR idle roller inside the PTR unit. The image transfer belt (ITB) runs between these rollers.
- Cams on each end of the PTR roller shaft, rotated by the PTR separation motor, raise and lower the roller to open and close the nip.
- When the rotation of the PTR roller moves the actuator on the end of roller into the gap of the PTR lift sensor, this turns the motor off. This is the home position with the rollers separated.
