Analyzing calibration data to detect and correct maintenance issues

Abstract

Systems and methods for detecting printhead misalignment are disclosed. A method includes receiving, for each of multiple printheads, multiple tone response curves (TRCs), each TRC associated with an inkjet of the printhead. The method further includes decomposing each TRC into a linear component and a non-linear component. The method further includes determining, for each printhead, a degree of misalignment based on the non-linear component of the TRCs associated with the printhead. The method further includes determining, for each printhead, a statistical deviation of the degree of misalignment from a norm for the multiple printheads. The method further includes, in response to the statistical deviation of the degree of misalignment exceeding a misalignment threshold, triggering an action.
