  • Patent number: 6585359
    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.

  • Patent number: 6386675
    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.

  • Patent number: 6375301
    Abstract: A replaceable reservoir cartridge is provided for use in an inkjet apparatus, wherein a reservoir cartridge with a first ink has been installed and which is to be replaced by a reservoir cartridge including a second ink. The replaceable reservoir cartridge includes a supply of fluid for flushing the first ink from the pathways in the inkjet apparatus. A memory is carried by the replaceable reservoir cartridge and couples to a processor within the inkjet apparatus when the replaceable reservoir cartridge is installed. The memory includes parameters, which, upon being accessed and utilized by a procedure stored in the processor, causes a printing of a plurality of disposable media sheets to enable a flushing of the first ink from pathways in the inkjet apparatus. The replaceable reservoir cartridge may be incorporated into a kit which further includes a storage media (i.e., a diskette) with a procedure for controlling the inkjet apparatus to enable operation of the flushing action.

  • Patent number: 6312116
    Abstract: One aspect of the present invention is a replaceable ink supply cartridge for providing a pressurized supply of ink to an ink-jet printhead of an ink-jet printer. The replaceable ink supply cartridge includes an activation portion for receiving a linear actuator associated with the ink-jet printer. The linear actuator has an activated state and an inactivated state. In the activated state the linear actuator is biased toward an extended position into engagement with the activation portion. In the inactivated state the linear actuator is in a retracted position. The ink supply cartridge portion provides a source of pressurized ink in response to the activated state of the linear actuator. Wherein in response to the inactivated state of the linear actuator the source of pressurized ink is non-pressurized.

  • Patent number: RE37874
    Abstract: In the preferred embodiment, an inkjet printer includes a replaceable print cartridge which is inserted into a scanning carriage. The print cartridge contains a regulator valve. An ink tube extends from the scanning carriage to a separate, disposable ink supply cartridge located within the printer. A second valve connected between the ink tube and the ink supply cartridge is automatically actuated when it is determined that the printer is not being used. The valve seal is more reliable than the inexpensive one-way valve seal in the disposable ink supply cartridge. The reliable valve seal prevents any air bubbles in the tube from expanding toward the ink supply cartridge, enabling the use of more flexible tubes which have less stringent air diffusion characteristics. In another embodiment, instead of a valve, a pressure source is connected to the ink tube to maintain the partial air pressure within the tube at approximately ambient pressure.
