Abstract
An apparatus and method for a dispenser with nozzles configured to eject lines of droplets of formable material onto a substrate in response to ejection signals. The fluid dispenser dispenses a first line of ejected droplets of formable material onto a first location on the substrate. A line camera generates camera signals that are representative of the first line of ejected droplets. The camera signals are analyzed to identify malfunctioning nozzles. The fluid dispenser dispenses a second line of ejected droplets of formable material onto a second location on the substrate that compensates for the one or more malfunctioning nozzles.
