Abstract
A printhead cartridge for a multi-printhead ink jet printer includes an array of ink jet nozzles and a heat sink for controlling the temperature of the nozzles. The heat sink is made up of a copper block and thinner copper wing regions extending from the block parallel to the array of nozzles. A passageway for coolant water is formed in the block and extends into the wings as a thinner channel. The block and the wing regions are mounted in thermal contact with the array of ink jet nozzles. The heat sink has the advantage that it allows the cartridges in the printer to be stitched together to cover the full width of a substrate.
