    摘要： 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.

    摘要： A system for printing on a multi-dimensional object includes a plurality of print heads, a mounting structure configured to receive an integrated object packaging and holder for an object and to movably mount on a support member, an actuator configured to move the mounting structure along the support member, and a processing device. The system also includes a non-transitory, computer-readable memory containing programming instructions that are configured to cause the processing device to control a movement of the mounting structure relative to the plurality of print heads, and operate the plurality of print heads to eject marking material onto an object mounted on the mounting structure.

    摘要： A print system and a method for curing marking material on an object using an active transparent display in a three dimensional (3D) object printer are disclosed. For example, the print system includes a plurality of printheads, a curing light source, a movable member to hold an object, an active transparent display and a controller to control movement of the movable member to move the object past the array of printheads, to operate the plurality of printheads to eject the marking material onto the object as the object passes the two-dimensional array of printheads, to control movement of the movable member, to control the active transparent display and to operate the curing light source to apply energy to cure the marking material, wherein the amount of energy that is applied to the object is controlled by a mask that is displayed on the active transparent display.

    摘要： An implementation of the present teachings includes a resistor structure for measuring a level of a print material such as a liquid metal print material within a reservoir of a printer such as a magnetohydrodynamic printer. The resistor structure includes a first electrode and a second electrode that are physically and electrically separated from each other. When positioned within the reservoir, the liquid metal physically contacts the first electrode and the second electrode. An electrical resistance between the first and second electrodes changes depending on the level of the print material within the reservoir. As the level of the print material decreases, the electrical resistance between the first electrode and the second electrode increases. The electrical resistance can be measured and used to determine a level of the print material within the reservoir.
