A system for monitoring an inkjet printing device and predicting failures or maintenance needs. The system includes one or more memory devices; a print analysis engine stored in the one or more memory devices to monitor the print output from the inkjet printing device, operation of the inkjet printing device, or any combination thereof; and one or more processor devices to perform actions, including: monitoring print output from the inkjet printing device, operation of the inkjet printing device, or any combination thereof; based on the monitoring, predicting a failure or maintenance need of the inkjet printing device; based on the prediction, suggesting or performing maintenance on the inkjet printing device to address the predicted failure or maintenance need; and, after maintenance has been performed, monitoring the print output, operation of the printing device, or any combination thereof to determine whether the predicted failure or maintenance need has been resolved.

Systems and methods for predicting printing device failures or maintenance needs

A method for adjusting a modifiable printing parameter of each of a plurality of printing elements of a printing device includes printing a plurality of test charts for each of the printing elements at different values of the modifiable printing parameter; measuring a variance of a printing density for each of the test charts; analyzing the measured variances for each of the printing elements; individually selecting a value of the modifiable printing parameter for each of the printing elements based on the analysis; and applying the selected value of the modifiable printing parameter for each of the printing elements to the printing device. Software density compensation can be applied to further reduce the variance of the printing density.
