Using a finned structure on a moving printhead to transfer heat via a thermal coupling agent to a mating large volume finned rack permits significant heat transfer without greatly adding to the moving printhead mass. A major factor limiting the performance of many serial printers is the total amount of heat that can be dissipated safely by the printhead. Typically, a finned heat sink is attached to the printhead and travels with the printhead carriage as it scans back and forth across the page. The moving fins dissipate heat directly to the ambient air by convection. However, if the heat dissipation requirements are severe, the required heat sinks become very large.
