Abstract
A pagewidth inkjet printer including: a printhead assembly having an elongate pagewidth array of inkjet nozzles, chambers and thermal bend actuators formed using MEMS techniques; wherein the array extends at least 36 inches (914 mm) in length; and, the printhead assembly being constructed and arranged such that adequate heat dissipation occurs at equilibrium operating conditions without a forced heat exchange system.
Claims4
A pagewidth wide format inkjet printer that comprises
- a printhead assembly having an elongate pagewidth array of micro electro-mechanical inkjet nozzles, chambers and thermal bend actuators;
- wherein the array extends at least 36 inches (914 mm) in length;
- and
- the printhead assembly is configured so that power consumed by the printhead assembly is sufficiently low to cause a majority of heat generated by the thermal bend actuators to be dissipated by ink ejected through the nozzles.
