Abstract

A method of operating a printing system includes identifying groups of nozzles of a plurality of nozzles of a printhead device. The method also includes ejecting fluid drops by the printhead device from nozzles thereof and along corresponding firing paths. The method also includes controlling movement of a detector carriage including a plurality of drop detectors of a drop detector array with respect to the printhead device by a control module to align each one of the drop detectors with the respective firing paths corresponding to the respective nozzles at a predetermined time. The method also includes sensing the firing paths corresponding to the nozzles to detect a presence of the fluid drops by the drop detectors such that each one of the drop detectors senses at a same time a respective firing path corresponding to a respective nozzle for a plurality of groups of nozzles.
