摘要： A method of operating a device to receive a print medium is disclosed. Rotation of a receiving device to receive a print medium is detected, whereby the rotation is caused by an external force. An assisting force is applied to further rotate the receiving device in response to the detected rotation.

摘要： According to an example, a media loading device may comprise a motor and a leading-edge sensor. The motor may rotate a media roll having a leading-edge in a winding direction and unwinding direction, the motor being controlled by a processor. The leading-edge sensor may comprise a pivot arm and a detecting element. The pivot arm may contact the media roll and the detecting element may issue a leading-edge presence signal to the processor upon contact between the detecting element and the leading-edge occurs.

摘要： According to an example, a media roll support may comprise a sliding element movable along a guide, a hub to receive the media roll and a coupling plate. The hub may comprise an elastic element biased towards a first side of the media roll. The coupling plate may be attached to the hub and to the sliding element. Upon holding the media roll, a deformation of the elastic element may tilt the sliding element. The tilting of the sliding element may lock the sliding element movement, thereby preventing its movement.
