摘要： An improved microelectromechanical device, such as a thermal ink jet die or printhead, is formed by the alignment of two planar substrates bonded together by an intermediate thick film layer of patterned polymeric material, such as polyimide. The improved device has a fully cured, patterned thick film layer which is planarized by chemical-mechanical polishing-to improve the bonding strength between the substrates. The planarization removes topographical formations generated during the deposition of the thick film layer and/or during the patterning of the recesses therein.

摘要： A printhead with a printhead die, an ink manifold and heat sink substrate has a continuous sealing surface surrounding the printhead die which is formed by the ink manifold, heat sink substrate and filler material disposed therebetween. The filler material acts as caulking to eliminate gaps around the printhead die, particularly between the ink manifold and heat sink substrate, and to provide a smooth surface for abutment with a capping member. A fluid-tight seal is obtained between the capping member and the continuous sealing surface on the printhead, thus preventing the drying out of ink in the nozzles through evaporation of volatile ink components. In some priming nozzle configurations, the leaktight seal also facilitates priming of the printhead.

摘要： A method of extending the useful life of a printbar for black ink in a multi-color printbar, full width array color ink jet printer by checking each nozzle in the printbar for droplet ejection; identifying any nozzle which fails to eject a droplet as a problem nozzle, and substituting at least one droplet from a nozzle in another printbar having a different color of ink. The substitute fill-in with a cyan droplet, cyan and magenta droplets, or cyan, magenta, and yellow droplets for process black prevents a missing spot and provides adequate printing quality for black printing, such as, for text, so that immediate printbar replacement is avoided, thereby extending the printbar life.

摘要： A bubble jet printing device is optimized for extended operation by preventing heat buildup within the printhead and ink supply. Several configurations provides for the addition of heat sinks of appropriate dimensions either directly to the printhead or to an electrode board bonded to the printhead. Plated holes through the electrode board increase heat flow away from the printhead. According to another aspect of the invention, the ink supply cartridge has thermally conductive particles dispersed therethrough to effectively increase its capacity to radiate heat away from the printhead.

摘要： A cleaning apparatus for a recording head in a magnetographic printing device of the type having a movable magnetic imaging tape in endless belt form is disclosed. The apparatus is especially effective for cleaning thermal printheads for thermoremanent magnetic imaging systems, and comprises a cleaning member adapted for reciprocal movement into and out of a nip formed by the magnetic tape and the printhead. In one embodiment, the cleaning member is a flexible substrate attached at one end to a rotatably mounted spool. The substrate is wound on the spool with the loose end resting on a guide plate and confronting the nip. The spool is periodically rotated to drive the substrate through the nip while the tape is moving and then is rotated in the opposite direction to rewind the substrate and withdraw it from the nip. In another embodiment, the cleaning member is a flexible substrate which is maintained in a planar configuration by parallel guide plates. A tractor wheel drive reciprocally moves the cleaning member into and out of the nip. The cleaning member may be a non-conductive, woven material having open spaces therein or a two layered composite having a non-conductive screen on one side to contact the tape and a carpet of short bristles on the other side to clean the printhead. Optionally, lateral movement of the cleaning member is provided after it enters the nip and the heating elements of the printhead may be momentarily energized to heat and soften the toner accumulated on the printhead to enhance the cleaning efficiency of the apparatus.

摘要： A priming element for priming or maintaining the nozzles or orifices of an ink jet printhead in an ink jet printer. The priming element applies a vacuum or negative pressure generated by a suction device to the nozzles. The priming element includes a first wall and a second wall spaced from the first wall to define a passageway between the first wall and the second wall. One or more support members connect the first wall to the second wall and span the passageway to prevent the walls of the priming element from collapsing from the applied vacuum or negative pressure.

摘要： A movable priming station, for use with an ink jet printer having a printhead with a linear extended array of nozzles located on a planar surface thereof, is capable of priming a portion of the extended array of nozzles at one time by applying a vacuum to at least one nozzle located on the portion of the extended array. The movable priming station includes a support capable of moving along a length of the extended array of nozzles, a vacuum tube attached to the support for movement with the support and having a vacuum port adjacent to one end thereof. The support is controlled so that the vacuum port does not contact a nozzle-containing surface of the printhead when the support is moved laterally along the linear array of nozzles. The vacuum port can be maintained a predetermined distance, greater than zero, from the planar surface of the printhead by the support so that when the support is moved along the length of the extended array of nozzles while the support contacts the printhead, the vacuum port is located closely adjacent to without contacting the nozzle-containing portion of the printhead. Alternatively, the support can be moved away from the printhead during lateral movement thereof so as not to slide along the printhead.
