Inkjet printhead assembly having very high drop rate generation

摘要

An inkjet printhead assembly (12) includes at least one inkjet printhead (40/140/240/340/440) including N primitives (50/250/350/450) and an address having M possible address values. Each primitive includes a group of at most M drop generators (41/141). The address is cycled through all M address values to control a sequence of which one drop generator in the primitive is fired at a given time. One drop generator in the primitive can be fired simultaneously with one drop generator in each of the other primitives. A primitive to address ratio (N/M) of the printhead is at least 10 to 1. <IMAGE>
