Abstract:
A fluid cartridge, such as a cartridge for filling with ink for use in ink jet printhead includes a housing enclosing a wick chamber, the housing including a top wall. The housing also includes an ink chamber. A fluid conduit connects the ink chamber and the wick chamber. The outer surface of the top wall of the housing is formed with a recess. A vent opening through the top wall of the wick chamber, at the recess, provides communication between the wick chamber and the recess. A covering over the top surface of the housing encloses the recess. An outlet opening through an outer wall other than the top wall of the wick chamber provides fluid communication for the ink to flow from the wick chamber. One end of an overflow tube is in fluid communication with the recess in the top wall of the housing. The other end of the overflow tube opens to the ambient environment at another point on the exterior of the housing near the outlet opening so that the potential “wet” spots on the exterior of the cartridge are in the same area.
Abstract:
An image recording media determination system is used with an imaging processing device and is operative for determining whether to form an image on a sheet of image recording media that is fed from a media source. The image recording media determination system includes a determination device and a controller device. The determination device determines whether the sheet of image recording media is compatible with the image processing device. The controller device which is in communication with the determination device permits forming the image on the sheet of image recording material by the image processing device when the determination device determines that the sheet of image recording media is compatible with the image processing device. The controller device also prohibits forming the image on the sheet of image recording media by the image processing device when the determination device determines that the sheet of image recording media is incompatible with the image processing device. A method for practicing the invention is also described.
Abstract:
An apparatus which advances a sheet through a transfer zone and into registration with information developed on a moving member. The sheet is advanced to a position wherein a leading portion thereof is immediately ahead of the transfer zone relative to the forward direction of movement of the moving member and a trailing portion thereof is within the transfer zone. The leading portion of the sheet forms a presentation angle of 7-10 degrees with the horizontal. The trailing portion of the sheet is advanced through the transfer zone at a first velocity and the leading edge of the sheet is advanced in a region immediately ahead of the transfer zone at a second velocity, which is less than the first velocity, so as to create a buckle in the leading portion of the sheet positioned immediately ahead of the transfer zone relative to the forward direction of movement of the moving member. The buckle functions to eliminate relative velocity between the photoconductive belt and any portion of sheet within the transfer zone so as to substantially eliminate slip between the sheet and the photoconductive belt.
Abstract:
A marking assembly includes a substrate and a marking device. The substrate includes a first portion made from a first material including a plurality of alignment features, and a second portion made from a second material affixed to the first portion of the substrate. The marking device is affixed to the second portion of the substrate and aligned to the alignment features of the first portion of the substrate.
Abstract:
A thermally-conductive fluid ejector carriage device is used to dissipate heat from a thermal fluid ejector module in a fluid ejection device. The thermally-conductive fluid ejector carriage device is molded from a polymer, or a polymer material including at least one thermally-conductive filler material. The thermal fluid ejector module is brought into contact with the thermally-conducting polymer carriage to dissipate heat. The polymer can be a highly thermally-conductive polymer. A method of manufacturing the thermally-conductive polymer carriage includes molding the carriage at least partially from a polymer that includes thermally-conductive filler materials, and contacting the thermally-conducting polymer carriage with the fluid ejector module. A method for use of the thermally-conductive fluid ejector carriage device includes establishing a heat flow path from the fluid ejector module to ambient air through the thermally-conductive fluid ejector carriage device.
Abstract:
A refillable fluid container system having a pressure control architecture in which persistent air bubbles are released from a capillary or foam fluid reservoir and are directed from an optical level sensing system in a liquid fluid reservoir.
Abstract:
A fluid reservoir sensing system includes a pair of optical prisms that reflect light when a fluid level is below one of the pair of prisms. The pair of optical prisms includes a low prism usable to sense a low liquid level in the fluid reservoir, and a high prism usable to sense a high liquid level in the fluid reservoir. The fluid reservoir sensing system optionally includes an emitter and a photosensor. The emitter projects light through at least one of the low prism to the low incident surface and the high prism to the high incident surface. The photosensor senses light reflected from the low prism while the liquid is below the low prism. The photosensor also senses light from the high prism while the liquid level is below the high prism.
Abstract:
A fluid cartridge for dispensing fluid, such as liquid ink for a drop on demand ink jet printer, includes a housing that encloses a capillary chamber, and has an outlet port through the one wall of the housing into the capillary chamber. Capillary material in the capillary chamber is arranged so that it has a higher density adjacent the outlet port than away from the outlet port, to enhance the flow of the fluid toward the outlet port. The interior of the capillary chamber is structured to provide greater compression to the capillary material around the outlet port, and provide stability to retain the variable compression of the capillary material.
Abstract:
An ink tank which has an ink delivery port chamber and one or more free ink chambers is provided with free ink chamber ceiling heights which are lower than the ceiling height of the ink delivery port chamber to reduce the amount of air trapped in the ink tank when the ink tank is filled with ink, and to locate air trapped in the ink tank in the ink delivery port chamber.
Abstract:
A printer determines the characteristics of the ink of the replaceble ink cartridge by set of ink cartridges. Each ink cartridge is formed of a housing and includes marks on the exterior surface of the housing. The marks on the cartridge housing are arranged so that the marks on the several ink cartridges collectively form a pattern of marks. The printer electronically scans the pattern of marks, and automatically produces an indication in accordance with the pattern of marks to identify the brand and/or type of ink contained in the set of cartridges, the ink capacity of the cartridges, as well as to verify that an appropriate combination of cartridges has been installed. Printer performance characteristics, such as expected print yield, can be determined based on the indication produced by scanning the pattern of marks.
