System and method for compensating for weak, intermittent, or missing inkjets in a printhead assembly

摘要

A system enables surrounding inkjets to be used to compensate for missing, intermittent, or weak inkjets without requiring additional passes of the image substrate or slowing the printing process. The system includes a printhead firing signal generator (204) configured to generate a plurality of inkjet firing signals with reference to a set of predetermined firing signal parameters (212), and a firing signal adjustment circuit (208) configured to modify at least one predetermined firing signal parameter to increase a first mass of liquid ink ejected by an inkjet proximate a defective inkjet in response to a signal identifying the defective inkjet.
