Abstract: A three-dimensional object printer compensates for variations in ejected material drop volumes by adjusting firing signal parameters. The printer includes an optical sensor that generates height measurement data of columns of material in a test pattern. Differences between the height of columns of material in the test pattern formed by the ejectors in the printhead and the expected height of the columns are compared to a predetermined range to detect drop variations that are out of tolerance. The modification of the firing signal parameter adjust the operation of the ejectors to bring the volume of the drops ejected by the ejector within tolerance range to reduce the ink drop velocities of the ejected drops within a predetermined range.
