摘要： Techniques for liquid replenishment in a printer/plotter. An ink delivery system (IDS) is employed wherein the on-carriage spring reservoir of the print cartridge is manually and securely connected to the off-carriage reservoir. A pen cartridge that uses an internal spring to provide vacuum pressure is connected from an inlet port through a unitary coupler to an ink reservoir located off the scanning carriage axis. The coupler serves to align as well as to secure two mating valves to securely hold them together in an open latched position which is not intended to be modified or disconnected until the entire ink supply has been depleted. A replaceable ink supply module for providing replenishment of an inkjet printhead includes a collapsible bag, an enclosure box, a connective tube, and an on/off valve. These four components are incorporated into a composite sealed system which remains intact during shipment, storage, installation and operation. The collapsible bag is placed inside the protective enclosure box and has an end-connect outlet permanently attached to one end of the connective tube. The other end of the connective tube carries a permanently attached on/off valve designed for engagement with an inlet valve of an inkjet printhead.
摘要翻译：打印机/绘图仪中液体补充技术。使用墨水输送系统（IDS），其中打印墨盒的托架上的弹簧储存器手动且牢固地连接到非托架储存器。使用内部弹簧提供真空压力的笔筒从入口端口通过单一联接器连接到位于扫描托架轴线上的墨水储存器。联接器用于对准以及固定两个配合阀，以将其牢固地保持在一起打开的锁定位置，该位置在整个供墨已经耗尽之前不打算被修改或断开。用于提供喷墨打印头补充的可更换墨水供应模块包括可折叠袋，封闭盒，连接管和开/关阀。这四个组件被并入复合密封系统，在运输，储存，安装和操作期间保持完整。可折叠袋放置在保护外壳内，并具有永久连接到连接管一端的端连接出口。连接管的另一端承载设计用于与喷墨打印头的入口阀接合的永久附接的开关阀。

摘要： A unitary coupler and method is provided for interconnecting an ink supply with an inkjet printhead. The coupler includes a first set of latching surfaces for attaching the coupler to the printhead; a second set of latching surfaces integral with the coupler for locking engagement with an inlet valve from an off-carriage ink supply; and alignment guides at one end for receiving the inlet valve. In a preferred method the coupler is initially attached to the printhead and subsequently attached to the inlet valve from the ink supply.
