Abstract: In one example, a printer having a rotation mechanism coupleable to a liquid-ejecting printhead in the printer. The printer includes a controller coupled to the rotation mechanism to control the rotation mechanism to intermittently rotate the printhead, during a non-printing time, from a first orientation relative to vertical to a second orientation relative to vertical and back to the first orientation.

Abstract: A fluid supply includes a container (100, 300) containing a bag (102, 302) and a valve (104, 304).

Abstract: A fluid supply includes a container, a bag within the container and a cap. The cap provides a fluid interface in communication with an interior of the bag and a pressurization interface in communication with an interior of the container adjacent an exterior of the bag. The pressurization interface has a channel that concentrically extends about the fluid interface.

Abstract: A labyrinth seal structure includes a gland structure for providing a fluid seal between a first surface and a second surface, and redundant labyrinth fluid flow paths between a first side of the seal structure and a second side of the seal structure.

Abstract: Example embodiments of pressure sensors are illustrated and described.

Abstract: Alternative methods for refurbishing a single-use ink delivery container for a printing system are described. The refurbishing methods include electrical and mechanical reconfiguration or replacement of original elements on the ink delivery container. Each method utilizes an existing ink fluid outlet, electrical connector and an information storage device on the ink delivery container.

Abstract: 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.

Abstract: A printhead assembly includes a carrier having a fluid manifold defined therein, a plurality of printhead dies each mounted on the carrier and communicating with the fluid manifold, and a fluid delivery assembly coupled with the carrier and communicating with the fluid manifold.

Abstract: Techniques for air management in an inkjet printing systems. A method includes providing an ink supply for holding a supply of liquid ink, the ink supply including high barriers to air diffusion, filling the ink supply with a quantity of liquid unsaturated ink, storing the filled ink supply for a storage time interval or until needed, installing the ink supply in an inkjet printing system including an inkjet printhead, supplying unsaturated ink from the ink supply to the inkjet printhead for printing, and allowing the unsaturated ink to absorb air introduced into the printing system, and ejecting droplets of the liquid ink from the printing system during the printing.

Abstract: An ink supply for an inkjet printing system, the ink supply having one or more areas of relatively high air diffusion through one or more structures comprising the ink supply. One or more air diffusion barrier structures shield the one or more areas of relatively high air diffusion from air diffusion, and a quantity of liquid unsaturated ink is disposed in the ink supply.

Abstract: The described embodiments relate to a print cartridge that can be configured to receive ink from one of at least two possible ink paths depending upon a desired printer configuration. In one exemplary embodiment, the print cartridge has a body configurable to receive ink from at least two different ink supply configurations, and a fluid interface that when coupled with the body effectively selects one of the ink supply configurations.

Abstract: In the preferred embodiment, an inkjet printer includes a replaceable print cartridge which is inserted into a scanning carriage. An ink tube extends from the scanning carriage to a separate ink supply located within the printer. A fluid interconnect on one side of the print cartridge connects to a fluid interconnect on the carriage when the print cartridge is inserted into the carriage to complete the fluid connection between the external ink supply and the print cartridge. In one embodiment, the fluid interconnection is made between the print cartridge and the ink tube simply by placing the print cartridge into a stall in the scanning carriage. The print cartridge has contact pads on another side. The contact pads electrically contact electrodes on the carriage when the print cartridge is placed in the stall.
