Appl. No.:

10/044305

Inventors:

Jason S. Dewey - San Diego CA

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

B41J 214

US Classification:

347 49, 347 37

Abstract:

A device and method for supplying ink to ink jet printer heads comprising first and second carriage portions non-rigidly coupled such that the two carriage portions are free to rotate independently about their guide rod axis, but are constrained to move together axially. The first carriage portion contains one or more ink jet cartridges supplied with ink via connecting tubes having self-sealing septum attached to corresponding ink outlets on the second carriage portion. The ink outlets on the second carriage portion preferably comprise valves with actuators. The actuators preferably act to secure the septum within the ink outlets, and are preferably disposed such that the valve is closed when the actuator is raised, and open when the actuator is lowered.

International Classification:

B41J002/01

US Classification:

347102, 400679, 400693, 1014241

Abstract:

An ink drying apparatus for an ink jet printer includes an internal heating apparatus. The heating apparatus comprises gas flow restrictors for air that enters the heating apparatus. The gas flow restrictors may be formed as dual horizontal slots which are sized to maintain a higher air pressure in the heating apparatus as compared to the air pressure in a region within the ink drying apparatus that is outside of the heating apparatus.

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

B41J002/14

US Classification:

347 49

Abstract:

An ink jet printer apparatus is adapted to secure a print cartridge which includes an open container having a top opening; a porous ink-absorbent in the container; a print head in ink communication with the porous ink-absorbent; a top cover lid adapted to be placed on the container, over the top opening, to close the container; and an ink conduit needle mounted on the top cover lid to longitudinally extend in a horizontal orientation above the porous ink-absorbent when the cover lid is placed on the container, so that a print ink can descend freely by the force of gravity from the ink conduit needle onto the porous ink-absorbent and from the porous ink-absorbent down to the print head. The ink jet printer apparatus has a resilient septum; an ink delivery connection to the septum; a stall for receiving the print cartridge in a substantially horizontal direction, so that the ink conduit needle mounted on the top cover lid is horizontally inserted through the septum; and a cover door movable closed to cover the print cartridge when the print cartridge is received in the stall, and adapted to secure the print cartridge in place within the stall to ensure that the ink conduit needle cannot be dislodged from the septum.

Assignee:

Eastman Kodak Company - Rochester NY

International Classification:

B41J 23/00

US Classification:

347 37

Abstract:

An ink jet printer includes a carriage mounted on a guide. The carriage provides a transverse movement to a printhead. The carriage includes an upper carriage component adjacent to a rear support wall of the ink jet printer and a lower carriage component mounted to the upper carriage component. A slider is disposed between the upper carriage and the rear support wall. The slider includes a rigid substrate with a hole or an eyelet forming a hole. A pin secured to the carriage engages the hole and allows the slider to rotate up to 360 degrees around the pin. The slider includes a fabric with extended fibers secured to the substrate or directly to the carriage in order to resist static charge accumulations and lower friction.

Abstract:

A print engine for an inkjet printer which has a media path extending past a printhead assembly along a paper axis, has an elongate printhead carriage extending transverse to the paper axis, a series of interfaces for supplying ink to respective printhead modules spaced along the printhead carriage such that during use, the printhead modules span the media path and ink conduits connected to the interfaces for feeding ink to the printhead modules. The printhead carriage has a series formations to position the ink conduits such that they all extend away from the interfaces in a direction transverse to the long axis to a common side of the printhead carriage.

US Classification:

347 36, 347 34

Abstract:

A printing system that has a media feed assembly for feeding different sizes of media along a media path, the media path having a width corresponding to a maximum width of media that can be printed by the printing system. The system also having a printhead assembly positioned on a first side of the media path and spanning the width of the media path, an aerosol collection duct with an opening on the first side of the media path and a spittoon system positioned on a second side of the media path opposing the first side. The printhead assembly is configured to eject non-printing ink drops from any section not required to print media that is less than the maximum width, and the spittoon system is configured to collect the non-printing ink drops.
