1. An apparatus for cleaning an advancing surface in a printing device, comprising:
- a continuously recirculating cleaning belt having a perimeter;
a cleaning press roller to bring the cleaning belt in contact with the surface;
a cleaning drive roller to continuously recirculate the cleaning belt; and
a steam guiding member interiorly located within the perimeter of the cleaning belt to direct a steam flow towards the cleaning press roller at an opposite side of the cleaning press roller to a side at which the cleaning press roller is to bring the cleaning belt in contact with the surface;
wherein the steam flow interacts with a substance on said surface to clean a portion of the surface.

12. An apparatus for cleaning a roller surface in a printing device, the apparatus comprising:
-
a chamber having walls defining an open side facing the roller surface; a continuously recirculating cleaning belt having a perimeter; a cleaning press roller arranged inside the chamber to bring the cleaning belt in contact with the surface at a contact area; a cleaning drive roller to continuously recirculate the cleaning belt; a manifold interiorly located within the perimeter of the cleaning belt to guide a steam flow towards the cleaning press roller at an opposite side of the cleaning press roller to a side at which the cleaning press roller is to bring the cleaning belt in contact with the roller surface; a plurality of barrier units inset and separate from the walls of the chamber to confine the steam flow and prevent the steam flow from exiting the chamber at the roller surface, the contact area positioned between the barrier units, a portion of the roller surface exposed between ends of the walls at which the walls are closest to the roller surface and the barrier units along an outwardly direction from the barrier units towards the walls and parallel to the roller surface; and an outlet formed in the chamber to exhaust the steam flow from the chamber. - View Dependent Claims (13)

14. A method of cleaning a surface in a printing device, comprising:
-
continuously recirculating a cleaning belt via a cleaning drive roller, the cleaning belt having a perimeter; bringing the cleaning belt in contact with the surface via a cleaning press roller; guiding a steam flow towards the cleaning press roller at an opposite side of the cleaning press roller to a side at which the cleaning press roller is to bring the cleaning belt in contact with the surface, via a steam guiding member interiorly located within the perimeter of the cleaning belt; wherein the steam flow interacts with a substance on the surface to clean a portion of the surface. - View Dependent Claims (15, 16)
