Abstract
An image forming device includes a roll tensioner adapted to hold a medium roll rotatably mounted thereon for providing a printable medium strip to the imaging device. The roll tensioner comprises a torsion mechanism exerting torsion to the printable medium strip that tends to pull back the printable medium strip and, thus, to prevent slack of the printable medium strip, the roll tensioner further including a torsion control mechanism to prevent the torsion from getting too large to stop the rotation of the printable medium roll, the roll tensioner also including a clutch mechanism to prevent damage to the torsion mechanism.
