摘要： A replacement cartridge for replacing spent ink ribbon on a continuous printer. The cartridge interfaces with the printer including a print head past which a document is advanced, a drive for feeding the ribbon tape, and a source of vacuum for effecting vacuum zones in which the feeding tape is buffered against acceleration shock. Included in the cartridge are a supply and takeup reel for the ribbon and between which the ribbon extends in a defined feed path through a pair of tape buffering vacuum chambers upstream and downstream of the print head. Magnets secure the cartridge to the printer at a guided interface in registry with the operative components of the printer. Pre-loading the ribbon in the cartridge entirely threaded throughout its feed path, enables replacement to be performed in a minimum of time requiring only the removal of the spent cartridge and immediately replacing it with the cartridge containing the reload of fresh ribbon.
摘要翻译： 更换墨盒，用于更换连续打印机上的废墨带。 盒与打印机的接口包括打印头，文件被提前通过，用于馈送带带的驱动器和用于实现真空区域的真空源，其中进给带被缓冲以防止加速冲击。 墨盒中包括用于色带的供应和收卷卷轴，并且色带在限定的进给路径之间延伸穿过打印头上游和下游的一对带缓冲真空室。 磁铁将墨盒固定在打印机的引导界面上，与打印机的操作部件配准。 将墨带预先装入墨盒中，整个螺纹穿过其进纸通道，可以在最短的时间内进行更换，只需要卸下废墨盒，并立即用包含重新装入新色带的墨盒更换墨盒。
