Label Unwinder for Epson C6500A

Used to increase the input roll capacity, it unwinds automatically the rolls having face-out labels only.
The position of the 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.
