摘要： An ink jet printer apparatus is adapted to secure a print cartridge which includes an open container having a top opening; a porous ink-absorbent in the container; a print head in ink communication with the porous ink-absorbent; a top cover lid adapted to be placed on the container, over the top opening, to close the container; and an ink conduit needle mounted on the top cover lid to longitudinally extend in a horizontal orientation above the porous ink-absorbent when the cover lid is placed on the container, so that a print ink can descend freely by the force of gravity from the ink conduit needle onto the porous ink-absorbent and from the porous ink-absorbent down to the print head. The ink jet printer apparatus has a resilient septum; an ink delivery connection to the septum; a stall for receiving the print cartridge in a substantially horizontal direction, so that the ink conduit needle mounted on the top cover lid is horizontally inserted through the septum; and a cover door movable closed to cover the print cartridge when the print cartridge is received in the stall, and adapted to secure the print cartridge in place within the stall to ensure that the ink conduit needle cannot be dislodged from the septum.

摘要： An ink delivery system in an inkjet printer includes a printhead mounted on a carriage in the inkjet printer. The printhead has nozzles to eject ink droplets for image printing. The system includes an ink reservoir for delivering ink to the printhead. The ink reservoir is positioned so that the ink level is from 0 to 8 inches below the printhead. A pulsation dampener is connected between the ink reservoir and the printhead. The pulsation dampener includes two chambers within a body, wherein a weir separates the chambers. A resilient member is located in one of the chambers and a membrane covers the chambers and the resilient member. The resilient member provides a recovering force against the membrane. Embodied herein is a method of delivering ink to a printhead mounted on a movable carriage using the embodied ink delivery system.

摘要： An ink delivery system delivering ink with satisfactory ink flow rate and dynamic back pressure from a stationary ink supply station to a print cartridge on a movable carriage in an inkjet printer is disclosed. The ink delivery system comprises an ink container and an ink reservoir both residing in the ink supply station, and a flexible tubing connecting the ink reservoir to the print cartridge. The ink container has an internal cavity not open to atmosphere holding a supply of ink, and an air inlet channel and an ink exit channel. The ink reservoir has fluid channels to mate with the air inlet channel and ink exit channel on the ink container, and an air opening on the upper portion to connect the internal space of the reservoir to atmosphere and an ink exit port. The ink level in the ink reservoir is controlled by allowing the ink to rise to a level where the ink blocks the air channel into the ink container thereby preventing air to flow therethrough. Consequently, ink is stopped from flowing from the container into the reservoir until the level of ink falls such that it no longer blocks the air channel into the ink container.

摘要翻译： 公开了一种墨水输送系统，其将油墨具有令人满意的油墨流动速率和动态背压从固定供墨站传送到喷墨打印机中的可移动托架上的打印墨盒。 墨水输送系统包括墨水容器和位于供墨站中的墨水储存器，以及将墨水储存器连接到打印墨盒的柔性管道。 墨水容器具有不向保持供墨的大气开放的内部空腔，以及进气通道和出墨通道。 墨水储存器具有与墨水容器上的空气入口通道和墨水出口通道配合的流体通道，以及在上部的空气开口以将储存器的内部空间连接到大气和墨水出口。 油墨容器中的油墨水平通过使油墨上升到油墨将空气通道阻塞到油墨容器中从而防止空气流过其中的水平来控制。 因此，墨水停止从容器流入储存器，直到油墨水平下降，使得其不再将空气通道阻塞到油墨容器中。
