Method and apparatus for automatic corotron cleaning in an image production device
First Claim
1. A method for automatic corotron cleaning in an image production device, comprising:
- 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 and being determined by the default resolution of the image production device, 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.

9. An image production device, comprising:
-
a dynamic current monitor that monitors the dynamic current from the transfer power supply, the dynamic current being the current supplied to a photoreceptor of the image production device; and a corotron management unit that receives a first dynamic current reading from the dynamic current monitor, determines 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 and determined by the default resolution of the image production device, wherein if the corotron management unit determines that the first dynamic current reading exceeds the predetermined threshold, the corotron management unit sends a signal to a cleaning device to clean the corotron and determines that the corotron has been cleaned, receives a second current reading from the dynamic current monitor, determines if the second dynamic current reading exceeds the predetermined threshold, wherein if the corotron management unit determines that the second dynamic current reading exceeds the predetermined threshold, the corotron management unit sends a signal to prompt a user to replace the corotron in the image production device. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
