摘要:
A method for cleaning the printhead of an ink jet printer includes the steps of separating an ink container from the printhead, connecting a cleaning container containing cleaning fluid to the printhead, and drawing cleaning fluid through the printhead, thereby cleaning the printhead. A device for cleaning the printhead includes a cleaning container connector element and a cleaning container that are shaped substantially the same as an ink container connecting element and an ink container, respectively.
