US Classification:

347 19, 347 50, 347 86

Abstract:

An ink container for holding a supply of liquid ink for use in an inkjet printing system. The container includes a collapsible ink reservoir for holding a supply of liquid ink, and a multiple functioned chassis. The chassis rigidly supports an air inlet for receiving pressurized air from the printing system and an ink outlet for delivering pressurized ink to the system. The chassis supports a collapsible ink container by providing an attach surface over which the collapsible container is attached. The attach surface allows a relatively simple pleated bag construction to be used by providing a surface whose normal is substantially perpendicular to the longitudinal axis of the container. The chassis is adapted to engage with a pressure vessel opening, providing a seal that separates the pressure vessel from an outside atmosphere. The chassis provides a surface for outside electrical contacts along with locating means for a mating electrical connector, and provides pathways for them to be routed into the pressure vessel region. An efficient method of assembly of an ink container is described.

International Classification:

B41J 2175

US Classification:

347 86, 347 7

Abstract:

An ink container for an off-carriage printing system including an ink supply station. The ink container contains a collapsible reservoir filled with ink that is in fluidically connectable to a conduit that leads to a pressure regulator. The outlet of the regulator delivers ink to a printhead. A pressure vessel surrounds the reservoir. The system pressurizes the pressure vessel, which results in pressurized ink being delivered to the regulator. The ink container has a sensor that infers the actual volume of ink in the reservoir by sensing the relative position of the reservoir walls. This sensor is mounted between the pressure vessel and the collapsible reservoir. The sensor is electrically connected to pads that are accessible from the outside of the ink container. Leads route from the pads, through a seal zone, and to the sensor. The seal is provided by a compressed o-ring.

International Classification:

B41J 214

US Classification:

347 50

Abstract:

The present invention is a replaceable ink container for providing ink to an off-axis printing system. The printing system responsive to electrical signals from the replaceable ink container for controlling printer parameters. The ink container has a leading edge and a trailing edge relative to a direction of insertion of the ink container into the printing system. The replaceable ink container includes a fluid outlet disposed toward the leading edge. The fluid outlet is configured for fluid connection to a hollow needle associated with the printing system. The hollow needle extends in a direction opposite the insertion direction. Included in the ink container is a plurality of electrical contacts disposed on the ink container. The plurality of electrical contacts are configured for engagement with complementary electrical contacts associated with the printing system. Also included in the ink container is a guide member extending from the ink container along the insertion direction.

International Classification:

B41J 2175

US Classification:

347 86

Abstract:

An ink supply for an inkjet printer is provided with a main reservoir, which is typically maintained at ambient pressure. The main reservoir, which has flexible side walls supported by a rigid frame, is coupled to a variable volume chamber via a check valve which allows the flow of ink from the reservoir to the chamber and limits the flow of ink from the chamber to the reservoir. The chamber is coupled to a fluid outlet which is normally closed to prevent the flow of ink. However, when the ink supply is installed in a printer, the fluid outlet establishes a fluid connection between the chamber and the printer. The chamber is part of a pump provided with the ink supply that can be actuated to supply ink from the reservoir to the printer.

International Classification:

B41J 2175

US Classification:

347 86

Abstract:

The ink supply has an ink reservoir, a valve, a pressurizable chamber, and an outlet. The refilling is accomplished by directing ink from the outlet into the reservoir while the chamber is otherwise unpressurized so that the valve remains slightly open to permit the refill flow therethrough.
