Abstract
A printhead assembly that includes an elongate support beam having a silicon core, an intermediate elastomeric layer mounted to the core and an outer support structure mounted to the elastomeric layer. A plurality of printhead modules is mounted to the support beam. The printhead modules and support beam are configured so that the printhead modules are misaligned when the printhead assembly is at room temperature and move into alignment when the printhead assembly heats up to operating temperature.
