A web material dispenser includes a housing and a pivotable roll support assembly provided therein. A first mandrel is provided at a first attachment location of the roll support assembly to support a first roll of web material. A second mandrel is provided at a second location of the roll support assembly to support a second roll of web material. The web material dispenser permits one-handed operation to replace the rolls of web material and to change positions of the mandrels within the dispenser. The roll support assembly may have a linkage arm and/or a roll support arm. Positions of the first and second mandrels relative to the dispenser's opening can be switched by pivoting the linkage arm relative to the housing and by pivoting the roll support arm relative to the linkage arm. A method for switching positions of rolls in the web material dispenser is also provided.

A mandrel includes a shaft that can hold a supply roll of film. A primary button and one or more secondary buttons are located on the shaft. The primary button and the one or more secondary buttons are biased toward an extended position and are capable of moving to a retracted position. The primary button and the one or more secondary buttons retract to the retracted position during at least a portion of loading the supply roll of film onto the shaft. The retraction of the primary button to the retracted position causes retraction of the one or more secondary buttons to the retracted position. When the supply roll of film is in an aligned position on the shaft, the supply roll of film is maintained in the aligned position in part by one of the primary button and the one or more secondary buttons in the extended position.

A rotating member for a wrap dispenser includes a first portion defining an outer surface and an inner surface, the outer surface defining an outer diameter and the inner surface defining an inner diameter; a second portion defining an outer surface and an inner surface, the outer surface defining an outer diameter and the inner surface defining an inner diameter, wherein the inner diameter of the first portion is less than the inner diameter of the second portion, and wherein the outer diameter of the first portion is less than the outer diameter of the second portion; and a transition portion extending between the first portion and the second portion, the transition portion defining an inner surface, the inner surface defining an inner diameter, wherein the inner diameter of the transition portion tapers from the second portion to the first portion.

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.
