  • Publication number: 20120120164
    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.

  • Patent number: 7591549
    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.

  • Publication number: 20040257413
    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 the ink source, an ink outlet in fluid communication with the 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

  • Patent number: 6371605
    Abstract: The invention provides an improved ink jet cartridge for an ink jet printer and a method for making the improved ink jet cartridge. The method includes providing a thermoplastic, flexible web having an edge portion, a first side and a second side and providing a substantially inflexible frame member having at least one peripheral edge. Disposing the first side of the flexible web adjacent the peripheral edge of the frame, thereby defining a substantially closed cavity. Heat welding the edge portion of the web and peripheral edge of the frame to one another using a heated platen using a heat welding structure and conditions which minimize thinning of the flexible web on the bonding surface at least adjacent the substantially closed cavity. Minimizing the thinning of the flexible web adjacent the closed cavity substantially improves the weld and resulting reliability of the ink cartridge.

  • Patent number: 5002375
    Abstract: In a laser printer, light beams need to be focused onto a printing surface to form points where print indicia are to effect a print image. In a printer where it is desirable to have variable pitch print characters, a new method has been employed to create variable print character pitches. Multiple non-parallel points of light are emitted through a collimating lens onto a wedge shaped optical component which directs the multiple beams of light into parallel alignment. The optical wedge has one planar surface perpendicular to at least one light beam emitted through the collimating lens. This light beam is normal to the perpendicular planar surface and passes through the wedge without being deflected. The optical wedge also has one or more planar surfaces that direct the other light beams into parallel alignment with the undeflected light beam.

  • Patent number: 4943815
    Abstract: When cover (8) of the laser printer (3) is closed, absence of the replaceable cartridge (15) or the shroud assembly (9) will activate both an electrical and a mechanical interlock. A moveable switch actuator (16) on the shroud assembly will be absent if the assembly is omitted and will not find a guide ramp (46) if the cartridge is absent, thereby assuring power to the light source remains off. A shutter (13) also blocks the normal light path and is moved aside by a pin (14) on the cartridge, and therefore blocks light unless a cartridge is installed. Walls (31) on the cartridge surround the shutter during normal use to form a protective light baffle. The laser printhead (2) is fixed within the shroud so that separation requires a necessary electrical cable (72, 74) to be disconnected.

  • Patent number: 4790672
    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.

  • Patent number: 4616945
    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.

  • Patent number: 4606662
    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.

  • Patent number: 4592670
    Abstract: A paper feed release system is disclosed wherein a camming member is mounted on and acts with respect to the platen shaft to depress a paper feed release bar extending entirely across the paper feed mechanism such that only one end of said bar is depressed while the second end provides a pivot with respect to the frame supporting the paper feed mechanism. The paper feed rolls and shafts are supported on support plates which are engaged by the paper feed release bar and are caused to be depressed by the pivoting movement of the paper feed release bar with respect to the frame member, under the influence of the camming release member.
