Epson TM-C3500 Label Unwinder with 3" Core Holder

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

An external power supply 100/240VAC - 2.5A at 24V allows an electronic circuit to provide, through the tension arm, the adjustment of the rotation¶?s speed and rotation¶?s direction. A 2A fuse is used as protection.
