摘要： To provide a printing apparatus and a method for determining a service life of a cleaning mechanism, capable of more accurately determining a service life of a cleaning mechanism. For the purpose, a service life of a recovery unit is determined by multiplication of a number of times a blade wipes a face surface by a coefficient different depending on a quantity of liquid adhering to the face surface.

摘要： The present invention intends to provide a printing apparatus that can lessen a reduction in ejection performance caused by thickening, solidification, or the like of print liquid in an ejection port of a printing unit even in the case of stopping a print operation by the printing unit to perform a post-process on a print medium. The printing apparatus includes a post-processing part configured to, in a state of stopping the print operation by the printing unit, perform the post-process on a printed print medium as well as including an open/close unit configured to selectively perform a closing operation or an opening operation of the ejection port provided in the printing unit. Further, when the print medium is stopped in the post-processing part, the open/close unit is controlled so as to bring the ejection port into a close state.
摘要翻译：本发明旨在提供一种打印装置，即使在停止打印单元的打印操作的情况下，也可以减少在打印单元的喷射口中的打印液体的增稠，凝固等引起的喷射性能的降低以在打印介质上执行后处理。打印装置包括：后处理部，被配置为在停止打印单元的打印操作的状态下，在打印的打印介质上执行后处理，并且包括打开/关闭单元，其被配置为选择性地执行关闭操作或设置在打印单元中的喷射口的打开操作。此外，当打印介质停止在后处理部分中时，控制打开/关闭单元以使排出口处于关闭状态。
