摘要:
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. The guide member is configured for engaging a tapered guide member receiving slot associated with the printing system. This engaging repositions the complementary electrical contacts relative to the hollow needle to ensure proper alignment of complementary electrical contacts with the plurality of electrical contacts during insertion of the ink container into the printing system
摘要:
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 support an air inlet for receiving pressurized air from the printing system and an ink outlet for delivering pressurized ink to the system. The chassis support 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.

摘要:
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.

摘要:
An ink container for an inkjet printing system is described, including an assembly of a simple housing with caps bearing indicia and protective surfaces to enable effective handling, aligning, keying and latching of the ink container. The ink container includes an ink container housing, the housing including an ink reservoir and a fluid outlet in fluid communication with said reservoir. The fluid outlet is for providing ink to the inkjet printhead. The container further includes a separately fabricated first cap attached to an end of the housing, the first cap having a plurality of mechanical features that provide mechanical functions for the ink container. The end of the housing is a leading end relative to a direction of insertion of the ink container into the printing system. The mechanical functions can include positioning the ink container relative to the supply station, a keying function for preventing installation of an ink container in the supply station without a cap providing the keying function. The mechanical features can include a boss for protecting a leading surface of the ink container and the fluid outlet from physical damage. The trailing end of the housing has attached to it a second cap having a latch feature for latching the ink container in the supply station, and an oversized handle that prevents backwards insertion. The housing includes a pressure vessel that surrounds the ink reservoir, and the first cap is secured to the pressure vessel.

An ink container that includes a collapsible ink reservoir having first a side and a second side that are opposing, a first spiral conductive coil attached to the first side, a second spiral conductive coil attached to the second side, stiffeners disposed over the first and second coils, and a pressure vessel for pressurizing the outside of the ink reservoir.
摘要:
A printing system including an ink container having a memory and an ink level sensing circuit, a print cartridge having a memory, and a printer controller. Remaining ink level in the ink container is estimated pursuant to ink drop usage information provided by the ink container memory and ink level sense information provided by the ink level sensing circuit.
摘要:
A large variety of ink delivery systems for an existing ink-jet printing system are provided. The ink delivery systems include ink reservoirs of varying configuration and size which are capable of accommodating a variety of ink use rates. Each ink delivery system also has an electrical connector and an information storage device which are suitable for the various ink use rates. The information storage device may be a memory device circuit that provides enabling information to the printing system.
