摘要： A method for operating an ink jet printer that includes the steps of performing a printer turn-on printhead service on a printhead cartridge of the printer; resetting a page counter, an uncapped condition time counter, and an ink drop counter, wherein the page counter counts the number of pages printed, the uncapped condition time counter counts the amount of time that the printhead cartridge is in the uncapped condition, and the ink drop counter counts the number of ink drops emitted by the printhead cartridge; printing a plurality of pages of print media; after a page is printed performing a post-prime printhead service if the printhead cartridge was primed during the printing of the page; and after a page is printed performing a print time printhead service if the printhead cartridge was not primed during the printing of the page and if (a) the ink jet printer has printed at least a predetermined number of pages since the page count counter was reset, (b) the printhead cartridge has been uncapped for at least a predetermined amount of time since the uncapped condition time counter was reset, or (c) the printhead cartridge has emitted at least a predetermined number of ink drops since the drop counter was reset.
摘要翻译：一种用于操作喷墨打印机的方法，包括以下步骤：在打印机的打印头墨盒上执行打印机打开打印头服务; 复位页计数器，无盖条件时间计数器和墨滴计数器，其中页计数器对打印的页数进行计数，无盖条件时间计数器计数打印头墨盒处于未加盖状态的时间量，并且墨滴计数器对打印头墨盒发出的墨滴数进行计数; 打印多页打印介质; 如果在打印页面期间打印头墨盒被打印，打印页面之后执行后期打印头服务; 并且如果在打印页面期间打印头墨盒未被打印，并且如果（a）喷墨打印机已经打印了至少预定数量的页面，因为页计数计数器被重置，则打印页面被打印后执行打印时间打印头服务，（b）打印头墨盒已经打开了至少预定的时间量，因为未加盖的状态时间计数器被复位，或（c）打印头墨盒已经发出了至少预定数量的墨滴，因为墨滴计数器被重置。

摘要： A sheet handling assembly includes a frame, a first assembly, and a second assembly, each assembly rotatably supported by the frame and configured to contactingly transport sheet media. A member is configured to rotate the second assembly in response to rotation of the member in a first direction. The frame is configured to pivot in the first direction in response to rotating the member in the first direction, and pivot in a second direction, opposite the first direction, in response to rotating the member in the second direction.
