Abstract
An inkjet printhead includes: a manifold having a plurality of ink outlets defined in a manifold surface; a plurality of printhead chips mounted to the manifold surface, each printhead chip having an odd number of color channels and each color channel having one or more respective rows of inkjet nozzle devices. A central color channel of each printhead chip is a dummy color channel that does not receive ink from the manifold.
