Abstract
A method and system for monitoring a print drum maintenance system of an image producing machine is disclosed herein in various embodiments. A test pattern is printed on the print drum, and imaged with an image-on-drum detector to determine a printed pattern response. The print drum is then cleaned again imaged with the image-on-drum detector to determine a cleaned print drum response. A cleaning efficiency is computed by comparing the imaged test pattern response to the imaged cleaned print drum response and determining if a failure condition exists by comparing the computed cleaning efficiency to predetermined limits. A corrective process is performed if the failure condition does exist, the corrective process including changing parameters of the drum maintenance system according to the computed cleaning efficiency. The changed parameters are compared to predetermined thresholds and, if not exceeding the thresholds, the cleaning is repeated after the parameters are changed.
