ABSTRACT:
A method and apparatus for predicting blade life in an image production device is disclosed. The method may include retrieving a number of print starts, a number of print cycles, a wear rate for print starts, and a wear rate for print cycles from a memory, calculating wear of a cleaning blade based on the number of print starts, the number of print cycles, the wear rate for print starts, and the wear rate for print cycles, wherein the wear rate for print starts and the wear rate for print cycles are weighed differently, determining if the calculated wear of the cleaning blade exceeds a predetermined threshold, wherein if it is determined that the calculated wear of the cleaning blade exceeds a predetermined threshold, sending a notification that the cleaning blade needs to be replaced.
