1. A media loading device to receive a media roll having a leading-edge, the media loading device comprising:
a motor to rotate the media roll in a winding direction and an unwinding direction, being the motor to be controlled by a processor; a leading-edge sensor comprising:
a pivot arm to contact the media roll; and,
a detecting element protruding from below the pivot arm, the detecting element having a contacting surface and being to issue a leading-edge presence signal to the processor upon contact with the leading edge,
wherein the detecting element comprises a rolling element having the contacting surface and the detecting element comprises a sensor to detect a rotation of the rolling element, wherein the contact with the leading edge causes the rotation of the rolling element, and wherein the sensor is to issue the leading-edge presence signal to the processor based on the detection.
