Abstract
A method and apparatus for automatic corotron cleaning in an image production device is disclosed. The method may include receiving a first dynamic current reading, the dynamic current being the current supplied to a photoreceptor of the image production device, determining if the first dynamic current reading exceeds a predetermined threshold, the predetermined threshold being a threshold set on the allowable variation in the dynamic current value, wherein if it is determined that the first dynamic current reading exceeds the predetermined threshold, sending a signal to a cleaning device to clean the corotron, determining that the corotron has been cleaned, receiving a second current reading, determining if the second dynamic current reading exceeds the predetermined threshold, wherein if it is determined that the second dynamic current reading exceeds the predetermined threshold, sending a signal to prompt a user to replace the corotron in the image production device.
