Abstract: A printer detects inoperative inkjets during printing of three dimensional objects. The printer includes an electrically conductive substrate onto which a printhead ejects building material in a test pattern. A plurality of electrically conductive members arranged in a pattern corresponding to the test pattern are moved a predetermined distance towards the substrate so ends of the members either contact the surface of the substrate or the building material on the substrate. An electrical current source coupled to the substrate produces a current in those members contacting the substrate. Thus, the inkjets corresponding to the members in which an electrical current is produced are identified as inoperative and the printing of an object can be suspended to take remedial action with regard to the printhead.

Abstract translation: 在打印三维物体时，打印机检测到不可操作的喷墨。 打印机包括导电基板，打印头以测试图案喷射建筑材料。 以对应于测试图案的图案布置的多个导电构件向衬底移动预定距离，因此构件的端部可接触衬底的表面或衬底上的建筑材料。 耦合到衬底的电流源在与衬底接触的那些构件中产生电流。 因此，对应于其中产生电流的部件的喷墨打印机被识别为不可操作，并且可以暂停打印物体以对打印头采取补救措施。

Abstract: A sheet-receiving surface comprises retractable bars movable between a first position and a second position. The first position is a first distance away from a mounting support. The second position is a second distance away from the mounting support. The first distance is greater than the second distance. Pivot arms, having a first end and a second end opposite the first end, are rotationally attached at the first end to the retractable bars and rotationally attached at the second end to the mounting support. Bias elements, operatively connected to the pivot arms, bias the retractable bars to the first position. A link is operatively connected to the retractable bars and an actuator. The sheet-receiving surface accumulates sheets of media into sets of sheets. Responsive to operation of the actuator, the link applies a force to move the retractable bars to the second position, forming an opening to allow the sets of sheets to drop, forming a stack of sets of sheets.
