The invention described in the specification relates to an improved ink jet printer cartridge structure which includes a substrate carrier or nose piece upon which semiconductor devices for ink jet printheads are mounted. The substrate carrier has a top surface containing one or more substrate locator wells each well having well walls, a well base and at least one ink feed slot in each well base and side walls attached to the top surface along the perimeter thereof. One or more of the side walls contain fins for heat removal from the substrate carrier and at least two alignment devices attached adjacent at least one of the side walls for precisely aligning the substrate carrier in a printer carriage. Among the advantages of the substrate carrier is that it provides a suitable means for substrate alignment for multiple substrates, a means for cooling multiple substrates, a means for fixedly or removably attaching the carrier to a ink reservoir body and a means for accurately aligning the carrier and reservoir body in a carriage of a printer.

A heater chip module is provided comprising a carrier adapted to be secured directly to an ink-filled container, at least one heater chip having a base coupled to the carrier, and at least one nozzle plate coupled to the heater chip. The carrier includes inner side walls and a support section which together define an inner cavity. An edge feed heater chip is coupled to the carrier support section. The heater chip includes side walls. The support section includes first and second passages which define first and second paths for ink to travel from the container to the inner cavity. The inner cavity and the heater chip are sized such that a first side wall of the heater chip is spaced from a first inner side wall of the carrier and a second side wall of the heater chip is spaced from a second inner side wall of the carrier. A nozzle plate is coupled to the heater chip and the carrier. The nozzle plate has a width such that the nozzle plate extends over an outer surface of the carrier. Sealant material is provided in the inner cavity such that at least a portion of the first inner side wall of the carrier, at least a portion of the first side wall of the heater chip, a first section of the nozzle plate and the sealant material define a first sealed ink cavity for receiving ink passing through the first passage. Additional sealant material is provided in the inner cavity such that at least a portion of the second inner side wall of the carrier, at least a portion of the second side wall of the heater chip, a second section of the nozzle plate and the additional sealant material define a second sealed ink cavity for receiving ink passing through the second passage.
