Abstract:
A consumable supply item for an imaging device holds an initial or refillable volume of fluid. Users orient a housing to deplete the fluid in a direction of gravity toward a bottom surface of the interior en route to an exit port. The imaging device has a rotating latch to keep in place the supply item during use Users activate the latch to eject the supply item. The latch mates with a notch on the supply item. A first face of the notch angles to allow the latch to swing into and away from contact with the notch while a second face substantially parallels a side of the latch when the latch is engaged with the first face. The faces have differing angles and differing lengths. Further embodiments note angular degrees, biasing members, container slots, and consumer features of the supply item, to name a few.

Abstract:
A regulator adapted to regulate the throughput of an ink between an ink source and a print head includes: (a) a pressurized chamber including an ink inlet in fluid communication with and ink source, an ink outlet in fluid communication with a print head, and at least one flexible wall; and (b) a lever including a flexible arm extending along a portion of the flexible wall and an opposing arm operatively coupled to a seal biased to close the ink inlet when the lever is in a first position and to open the ink inlet to allow fluid communication between the ink inlet and the pressurized chamber when the lever is pivoted to a second position; where a lower pressure differential across the flexible wall causes the flexible wall to actuate the flexible arm, pivoting the lever to the first position (inlet closed), where a higher pressure differential across the flexible wall causes the flexible wall to actuate the flexible arm to pivot the lever to the second position (inlet open), and where a pressure change from the lower pressure differential to the higher pressure differential across the flexible wall causes the flexible wall to actuate and flex the flexible arm without causing the lever to pivot.
Abstract:
A pressed sleeve bearing is disclosed which is moldable out of plastic and which will provide a superior retaining characteristic, while at the same time will retain the designed interior diameter of the bearing, unaffected from the pressing forces and deformation. The region of engagement between the bearing and the supporting part is displaced axially from the bearing region so that any deformation of the sleeve will not be communicated to the bearing surface. The interior of the sleeve in the region of engagement is relieved to provide clearance for the shaft that will be inserted into the bearing.
Abstract:
A method of controlling a height of an encapsulant material on an inkjet printhead is provided. The method includes dispensing the encapsulant material on an outer portion of the inkjet printhead. The encapsulant material is then depressed to reduce its height on the outer portion of the inkjet printhead. The encapsulant material may be depressed directly after dispensing or before it completely cures. The encapsulant material may be completely cured before reducing its height. The height of the cured encapsulant material may be reduced by removing a top portion of the encapsulant material through machining operation. Reducing the height of the encapsulant material on the inkjet printhead minimizes the distance of the nozzle plate of the inkjet printhead to the printing media, thus improving print quality.
Abstract:
A consumable supply item for an imaging device holds an initial or refillable volume of ink. Users orient a housing to deplete the ink in a direction of gravity toward a bottom of the interior. The imaging device has a rotating latch. The latch mates with a top of the supply item to keep in place the supply item. Fluid exit and air venting ports reside on a side of the housing that gets inserted first into a container slot of the imaging device. A space separates the ports so a biasing member can push against the housing to assist in ejecting the supply item upon users activating the latch. The ports are separated a maximum distance to facilitate the ejection, while the exit port remains near a bottom to minimize stranding ink. Further embodiments note arrangements, distances and consumer features, to name a few.
Abstract:
A cartridge 12 for correction tape 22 is disclosed which utilizes a cam follower 40 operated pawl 50/ratchet 52 for feeding of the tape 22, where the pawl 50 is operated as a result of the movement of a cam follower 40 against a cam 40 on the support frame 10. As the cartridge 12 oscillates, the pawl 50 is displaced to increment the ratchet 52 to effect feed.
Abstract:
A single stepping motor 10 driven to effect ribbon feed, ribbon lift, correction tape feed, correction tape lift is disclosed. The stepping motor 10 controls a cam 60/follower 64 pair to effect lift through a connection link 54 to a depending coupling 56 on the ribbon cartridge 22. The link 54 provides accurate positioning of the ribbon cartridge 22 without regard to the cam position and further transmits ribbon feed motion through to the depending coupling to the ribbon driver 30. Correction tape feed is effected through link 54 controlling the oscillation of the cartridges 22, 24 relative to a tape feed cam member 44.

Abstract:
A method and system for purging bubbles from a fluid chamber of a micro-fluid ejection head containing a plurality of fluid chambers, an ejection actuator respectively associated with each of the fluid chambers, and a common fluid supply area for the fluid chambers. According to this exemplary method, one or more of the ejection actuators are pulsed with energy sufficient to expand a bubble present in one of the fluid chambers without substantially boiling the fluid in the common fluid supply area. A first temperature of the ejection head is maintained for a first period of time during bubble expansion so that the bubble in the fluid chamber is urged away from the fluid chamber. The ejection head temperature is decreased over a second period of time to lower the ejection head temperature to a second temperature lower then the first temperature.
