Abstract

A method increases the ability of a controller in a printer to detect weak or missing inkjets in the printer. The method includes generating a test pattern having at least twice as much ink as a typical test pattern used to detect weak or missing inkjets. The increased ink appropriately stresses inkjets to facilitate detection of weak or missing inkjets and the test pattern is transferred to media and removed from the printer to preserve the capacity of a drum maintenance unit to store residual ink removed from an imaging drum or belt.
