    • Apparatus and methods for maintaining flowability of solid-ink pellets when delivering solid-ink pellets from a container to an image-forming apparatus. The apparatus includes an extraction tube inserted into the container and also connected to a vacuum source. Suction produced by the vacuum source impels pellets into the extraction tube through an extraction inlet, but pellet agglomerations may clog the system. Such a clog produces an immediate pressure spike within the extraction tube, an event detected by the clog detector. An actuator, responsive to the clog detector, drives an agitating structure that breaks up agglomerations and restores smooth pellet flow. Alternative embodiments can include devices having only the clog detector or the agitating structure along with the clog detectors. Alternative implementations of the agitating structure provide means for accomplishing the pellet break up. The accompanying method detects the occurrence of a clog and responds by operating the agitating structure to break up agglomerations.
    • 当将固体油墨颗粒从容器输送到图像形成装置时,用于保持固体油墨颗粒的流动性的装置和方法。 该装置包括插入容器中并连接到真空源的抽出管。 由真空源产生的吸入通过萃取入口将颗粒推入萃取管中,但颗粒团聚可能堵塞该系统。 这种堵塞在提取管内产生立即的压力尖峰,由堵塞检测器检测到的事件。 响应于堵塞检测器的致动器驱动分解结块并恢复平滑颗粒流动的搅拌结构。 替代实施例可以包括仅具有堵塞检测器或搅拌结构以及堵塞检测器的装置。 搅拌结构的替代实施方案提供了完成颗粒分解的方法。 伴随的方法检测堵塞的发生并通过操作搅拌结构来分解聚集来响应。
