    Abstract: A self-advancing cleaner and a method of operating the self-advancing cleaner. In an embodiment, a rotatable member can engage a transport belt, wherein the rotatable member includes a cleaning surface comprising a surface sufficiently rough to collect and take away ink debris from the transport belt. During a cleaning operation the cleaning surface remains stationary while the transport belt moves in a sliding relative motion with respect to the cleaning surface, which allows the ink debris to be collected on the cleaning surface. Once an ink contamination level associated with the ink debris attains a threshold and a set friction exceeds the threshold, the self-advancing cleaner advances.

    Abstract: What is disclosed is an object holder for securely retaining an object while it is being printed in a direct-to-object print system and a direct-to-object print system configured to use various embodiments of the object holder of the present invention. In one embodiment, the object holder comprises a back support configured to slideably traverse a support member positioned parallel to a plane formed by at least one printhead configured to eject marking material on to a surface of an object A top and bottom arm are attached to the back support. At least two support braces are attached to the top and bottom arms. At least one restraining bar is slideably attached to the support braces such that the bar can be raised or lowered on to the object seated between the top and bottom arms. The bar physically retains the object while the object is being printed.

    Abstract: Disclosed is a system and method for cooling paper within a printer assembly that includes at least one misting assembly designed to mist an aqueous solution onto an unprinted surface of paper stock after a first side is printed. At least one convection accelerator assembly is designed to accelerate evaporation of the aqueous solution before the printed paper stock arrives at the at least one printing station for printing on the unprinted surface. At least one or more of a paper temperature, machine temperature, printhead temperature, and humidity sensor are operationally coupled to at least one controller assembly programmed to control at least one or more of misting, humidity, and airflow. The at least one controller assembly is designed to determine the heat to be dissipated into the airflow from the printed paper stock to obtain a targeted paper temperature and, therefore, the amount and placement of aqueous solution misted.
