摘要： An image output device includes a marking engine and a media path adjacent the marking engine. The media path has a media transportation direction and a media transport element (e.g., a nip drive, a belt drive, a suction drive, an air pressure drive, etc.) within the media path that moves the media along the media path in the media transportation direction. A drive motor is operatively connected to the media transport element. The drive motor provides drive force in a forward direction that causes the media transport element to move media along the media path in the media transportation direction. The drive motor can also provide the drive force in a reverse direction opposite the forward direction. A one-way drive transfer device (e.g., a one-way clutch, a one-way swing arm mechanism, etc.) is operatively connected to the drive motor. The one-way drive transfer device only transfers drive force from the drive motor when the drive motor operates in the reverse direction. The reverse direction drive of the motor, in conjunction with a one-way drive transfer device, can be used to perform the lock/unlock or the open/close of a jam clearance mechanism, baffle, or shield.
摘要翻译：图像输出装置包括标记引擎和与标记引擎相邻的介质路径。媒体路径具有媒体传送方向和介质路径内的媒体传送元件（例如，夹持驱动器，皮带驱动器，抽吸驱动器，空气压力驱动器等），其沿着介质路径沿着介质路径移动介质媒体运输方向。驱动马达可操作地连接到介质传送元件。驱动电动机沿向前的方向提供驱动力，使得介质传送元件沿着介质传送方向上的介质路径移动介质。驱动马达也可以向与正向相反的方向提供驱动力。单向驱动传递装置（例如，单向离合器，单向摆臂机构等）可操作地连接到驱动马达。当驱动电机反向工作时，单向驱动传输装置仅传输驱动电机的驱动力。电动机的反方向驱动与单向驱动传动装置相结合可用于执行卡锁间隙机构，挡板或屏蔽件的锁定/解锁或打开/关闭。

摘要： A method for purging an ink jet print head to clear ink jet orifices is provided. A purge cap forms a vacuum seal over the orifice plate of the print head. Multiple low pressure differential vacuum pulses are applied to the purge cap to remove debris and trapped air bubbles from the ink jet orifices. The low pressure pulses avoid cavitation inside the print head and reduce the amount of ink expelled during the purging process.

摘要： An integrated module for installation within a printer may include a module frame and a plurality of printer subsystem components. The module frame is configured to fit within a predetermined space within a printer and to connect to a printer frame positioned about the predetermined space. The plurality of printer subsystem components are configured to mount to the module frame. At least one printer subsystem component includes a default module media path and at least one diverter-directed module media path within the printer subsystem component. The at least one printer subsystem component is configured to connect to the module frame at a position that enables the default module media path and the at least one diverter-directed module media path to complete a printer media path through the predetermined space when the module frame having the printer subsystem component is connected to the printer frame.

摘要： An impact printer has a print band moving longitudinally around pulleys with one side of the band moving in contact along a rigid platen and the other side having engraved characters presented along a print line of a print medium (e.g. paper and ink ribbon). The leading edge of platen is squared off (e.g. sharp) to scrape contamination off the band. A row of hammers impact the print medium against the band between the hammers and an impact surface of the platen. The impact surface of the platen contains multiple longitudinal grooves which start slightly back from the leading edge of the platen and which prevent increased friction force between the band and platen from occurring as the band wears the platen impact surface smooth.
