摘要： A conical vent (14) for a cartridge (10) is located on an inner surface (20) of the cartridge. The conical vent includes a conical-shaped member (26) having a base (28) and an apex (30). An opening (32) extends through the center of the conical-shaped member (26) to provide an air passage for a cartridge (10). The opening (32) is adapted to create a capillary force on a small amount of liquid (59) that might enter the opening to prevent any remaining liquid from leaking through the opening. The vent also includes a groove or capillary trap (34) that encircles the base of the conical-shaped member. Also, a pair of upright walls (36) and (38) surround the conical-shaped member and cooperate with the capillary trap to divert liquid to the base of the conical-shaped member and away from its apex. A second conical-shaped member (52) integral with an outer surface (22) of the cartridge can be positioned directly opposite the first-mentioned conical-shaped member to help create and maintain the capillary force created in the opening (32). Another capillary trap (56), extending around the second conical-shaped member, traps any liquid that might escape through the opening.

摘要： An off-axis spring bag ink delivery system for an ink-jet printer/plotter. An auxiliary ink reservoir is located off-axis, and is coupled to an internal ink cartridge spring bag reservoir through a tube and check valve. A sensor determines when ink is to be pumped from the auxiliary reservoir into the interval reservoir. Ink does not flow from the auxiliary reservoir to the internal reservoir unless the check valve break pressure is exceeded, when the ink is being actively pumped in response to the sensor indication. The sensor can be a leaf spring switch built into the ink cartridge, which opens when the spring bag collapses beyond a leaf spring set point. The sensor can also be a pressure switch responsive to the negative pressure within the internal reservoir, which activates the auxiliary reservoir pump when the magnitude of the negative pressure exceeds a set pressure magnitude, indicating the cartridge reservoir ink volume is low.

摘要： In a printer carriage adapted for holding multiple pen cartridges in separate compartments, each carriage compartment includes one or more key-coded barriers at an entrance to the compartment to provide a first level carriage lockout scheme against non-matching cartridge tabs. A second level carriage lockout is provided to differentiate between different families of print cartridges which successfully pass through the first level lockout, which second level is based on predetermined barrier floor configurations in the bottom of each carriage compartment which block non-matching wings on particular print cartridge families.

摘要： An ink-jet pen is disclosed that has a body of resilient felted polyurethane foam mounted in an ink chamber for ink retention and backpressure. A rectangular ink pipe extends from a bottom wall of the ink chamber between the walls of the ink chamber. A wire mesh filter is mounted to the ink pipe. The ink pipe and mesh filter extend into compressive contact with the foam to locally increase the capillarity of the foam. Any air that comes out of solution collects as a bubble in the rectangular ink pipe. This bubble does not block ink flow to the printhead, however, because the corners of the rectangular ink pipe provide a fluid capillary path. The bubble tends to form in a spheroid shape and does not extend into the corners of the ink pipe. In addition, rectangular filters are used, which reduces waste and expense compared to circular filters.

摘要： An off-axis ink delivery system for an ink-jet hard copy apparatus includes a multifunctional ink pump and flow switch device. A semipermanent, negative pressure, pen and printhead has a fluidic coupling to a static, refillable or replaceable, off-axis, ink reservoir via the ink pump and flow switch device.. The pen's mechanism for creating the negative pressure operational condition is used to pull ink from the reservoir when the ink pump and flow switch device is in an "open" position. Negative pressure reset, nozzle priming, pen air purging functions are also provided by the same ink pump and flow switch device. A system for each color ink is employed in the hard copy apparatus.

摘要： A method of detecting fluid drops ejected from a fluid applicator unit having nozzles. The method includes establishing a detection zone to detect detection fluid drops transmitted therein and ejecting a set of detection fluid drops through a set of nozzles of the fluid applicator unit through the detection zone to a detection receiving member. The method also includes ejecting a set of warm-up fluid drops through an other set of nozzles to a warm-up receiving member in a manner in which the set of warm-up fluid drops bypasses the detection zone. The method also includes detecting the set of the detection fluid drops ejected into the detection zone.
