1. A roller cleaning assembly including:
a main body support; a contact portion including an elongate cleaning surface for contacting an outside cylindrical surface of a roller, the contact portion being coupled to the main body support and moveable therefrom between a retracted position where the cleaning surface is remote from the roller and an engaged position where the cleaning surface is in contact with an outside cylindrical surface of the roller; a bladder positioned between the main body support and the contact portion, wherein the bladder is able to change between a deflated state and an expanded state by changing the pressure of a fluid contained within the bladder, wherein when the bladder changes from the deflated state to the expanded state the bladder pushes the contact portion into the engaged position and away from the main body support; and a bias coupled between the main body support and the contact portion wherein the bias acts to move the contact portion back to the retracted position when the bladder changes from an expanded state to a deflated state; wherein the main body support, the contact portion, and the bladder are elongate and substantially the same length as the length of the outside cylindrical surface of the roller, wherein the contact portion is positioned between the roller and the main body support, and wherein the bias is in the form of two elongate resilient sheets wherein a first elongate resilient sheet is located along one of the sides of the roller cleaning assembly and is attached between the main body support and the contact portion and wherein the second elongate resilient sheet is located along the other side of the roller cleaning assembly and is attached between the main body support and the contact portion.
