摘要：
A method of operating a printer enables the mass of the ink drops ejected by the printheads in the printer to maintained in an optimal range without measuring the drop mass being ejected by the inkjets in the printheads. After calibration of the printheads, the printheads are operated with electrical signals having different peak-to-peak voltages. The number of inoperable inkjets for each printhead is determined from image data of the ejected ink on the image receiving member and the number of inoperable inkjets for each printhead is compared to a predetermined threshold. The peak-to-peak voltage for the electrical signals used to operate a printhead is adjusted with reference to the number of inoperable inkjets and the predetermined threshold.
