The position of the unwinders tension arm is calibrated as follows:
- When the printer forwards the media for printing, the tension arm goes up,
the device unwinds the media.
- When the tension arm is in the middle position, the device is idle.
- When the printer pulls back the media, the tension arm goes down, the device rewinds it.
