To increase manufacturing yield, an array of ejection chambers in an inkjet printer includes at least one redundant ejection chamber. For each ejection chamber, there is a possible nozzle window, and these nozzle windows overlap. The ejection chambers are tested prior to nozzle formation to identify any non-functioning chambers, appropriately positioned within the respective nozzle windows to form uniformly spaced dots on a substrate, with at least one ejection chamber.
