Abstract
A media roll holder assembly for a roll is detachably supported in a printing system. A rotational drive includes a roll engaging element configured for fittingly engaging and driving a drive engaging element of a roller, for example an Oldham coupling. A first guide surface is configured to support and direct the roller in a loading direction. A second guide surface at least partially extends at an angle with respect to the first guide surface, such that movement of the roller over the first guide surface brings the drive engaging element in contact with the second guide surface. The second guide surface directs the drive engaging element into a predetermined orientation, which orientation aligns the drive engaging element with the roll engaging element in a loading orientation, such that further movement of the roller in the loading direction inserts the drive engaging element into the roll engaging element.
