Abstract: A cleaning assembly for a surface of a roller has a dry-ice container, a connector and an injector. The dry-ice container contains CO2. The connector has two ends and one end connects the dry-ice container. The injector is mounted on the other end of the connector, is coupled with the connector and the dry-ice container and allows CO2 to be sprayed out of the injector toward the surface of the roller. Because CO2 is solid when it is sprayed out of the injector toward the surface of the roller, the solid CO2 provides enough kinetic energy to residues in cells of the roller. Therefore, the residues can be removed from the cells. Additionally, after the solid CO2 impacts the surface of the roller, the solid CO2 sublimates directly to a gas CO2, so there is no stain or other spot to be remained on the surface of the roller.
