A thermal inkjet cartridge for an organic solvent-based ink includes a cartridge housing, a printhead attached to the housing, and a collapsible ink reservoir disposed in the housing. The ink reservoir has an opening through which ink is supplied to the printhead in fluid communication with the ink reservoir. The reservoir includes a basin member defining a first major portion of the ink reservoir and a movable plate defining a second major portion of the ink reservoir. At least one of the basin member and the movable plate includes a barrier layer for reducing the migration of solvent from the ink reservoir to an external environment.

A capping device for an ink jet print head, includes a base, the base configured to receive an ink jet print head comprising nozzles for ejecting ink in a print direction, and a cap assembly attached to the base and configured for movement between a closed position when the print head is not printing and an open position to allow for the ejection of ink from the nozzles when the print head is printing. The cap assembly includes a cover support configured for generally planar movement with respect to the base in a direction perpendicular to the print direction and a cover attached to the cover support in a generally planar relationship thereto. The cover is adapted to provide additional movement with respect to the cover support in a direction different from the planar movement in the direction perpendicular to the print direction.

An ink containment system for an inkjet cartridge, for storing ink for printing, comprises a rigid basin member and a rigid moveable plate. A flexible membrane is affixed to a surface of the basin member and to a surface of the plate forming an ink reservoir within the basin member, plate and flexible membrane. A spring-biased mechanism is disposed between the basin member and plate, for biasing the plate apart from the basin member, generating a negative pressure within the ink reservoir and the basin member remaining stationary relative to the movement of the plate. The basin member has a bowl-like configuration and the spring is seated within the reservoir in such a way that when the ink reservoir has collapsed due to depletion of ink, the flexible membrane and moveable plate are substantially flush with surfaces of the basin member.

A printing method includes providing a print head. The print head includes a valve and at least one orifice. Fluid is ejected from the orifice in a generally continuous stream. The fluid includes a conductive material. The fluid is deposited in a pattern on a substrate to form an electrically conductive deposit. At least a portion of the pattern includes a generally straight line.

Stream printing method

A system, including an ink supply system configured to supply ink to a printhead; and an autopurge unit configured to automatically clean the printhead. The autopurge unit includes a solvent supply in fluid communication with a solvent line, a solenoid housing, and a waste container. The solenoid housing includes a first solenoid assembly disposed within an ink line, wherein the ink line is in fluid communication with the ink supply and a first outlet that is configured to be in fluid communication with the printhead; and a second solenoid assembly disposed within a solvent line. The waste container is in fluid communication with a waste delivery line having a waste inlet. The waste inlet is configured to be in fluid communication with a waste line that is in communication with the printhead so that fluid waste from the printhead is deposited into the waste container.

Autopurge printing system

A one-piece, unitary clamp for a longitudinally extending structural member, such as a tube, is provided which can be mounted to a mounting surface such that the structural member received in the clamp is either parallel to or perpendicular to the mounting surface. Additionally, two clamps of the present invention can be fastened together to form a cross-over clamp, a T-clamp, or another compound clamp which will hold two structural members together in a desired relationship. The clamping arms of the clamp have an elastic hinge which allows an upper portion of the clamping arm to move relative to a lower portion of the clamping arm when the clamp is tightened. Additionally, when the clamp is loosened, the elastic hinge of the clamping arms cause the clamping arms to pull away from the structural member received in the clamp to fully release the grip of the clamp on the structural member.

This invention relates to a check valve (,) for use in an ink supply line (,) of an ink jet printing system (,) between an ink reservoir (,) and an inkjet printhead (,) so as to prevent de-priming of the printhead upon the latter being subjected to impact loads or the like. Specifically, the improvement of this invention comprises a one-piece check valve (,) of an elastomeric material having a flapper valve (,) movable between a closed position in which the flapper valve blocks the backflow of ink and an open position in which ink is free to flow past the check valve member to the printhead. The flapper valve (,) is defined by a slot (,) separating the flapper valve from the outer margin (,) of the check valve (,) and the flapper valve is integrally joined to the outer margin by a hinge portion (,) so as to enable movement of the flapper valve between its open and closed positions.
