Abstract
In a printer/plotter having a carriage for removably mounting one or more printhead cartridges, multiple pairs of aligned electrical interconnect pads provide signal transmission between printhead circuits and corresponding circuits on the carriage. A compliant foam material is positioned on the carriage to provide increased pressure for assuring conductivity across each interconnect pad junction. In a preferred embodiment, a thick block of compliant foam material having a flat upper surface is installed on the carriage for each printhead cartridge, and is positioned in an elongated rigid cavity of the carriage to push against the peripheral base portions of more than fifty dome-shaped copper interconnect pads which are densely packed on the flexible circuit.
