ABSTRACT:
A printhead assembly for an A4 pagewidth drop on demand printer includes a number of printhead modules situated along a metal channel. The metal channel is typically of a special alloy called “Invar 36”. Preferably the channel is nickel plated to help match it to the coefficient of thermal expansion of silicon, being the major component of each individual printhead module. The channel captures the printhead modules in a precise alignment relative to each other and the similar coefficient of thermal expansion of the “Invar” channel to the silicon chips allows similar relative movement during temperature changes.
