An inkjet printhead comprising:
- 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, each color channel having at least one respective row of thermally-actuated inkjet nozzle devices, each one of the inkjet nozzle devices having one corresponding nozzle,
- wherein a central color channel of each printhead chip is a dummy color channel having non-ejecting nozzles that do not receive ink from the manifold.
A printhead chip having an odd number of color channels, each color channel comprising at least one row of thermally-actuated inkjet nozzle devices, each one of the inkjet nozzle devices having one corresponding nozzle, wherein a central color channel of the printhead chip is a dummy color channel having non-ejecting nozzles that do not receive any ink.
