摘要:
An image quality control apparatus controls quality of xerographic images formed by a xerographic imaging system onto a recording medium when at least one sensor which is operative to provide signals to the xerographic imaging system for quality control malfunctions. The image quality control apparatus includes a controller device in communication with the xerographic imaging system. The controller includes a data collection device, a determining device and an input generating device. The data collection device collects and processes sensor data received from the at least one sensor while the at least one sensor is operative. The determining device determines whether the at least one sensor malfunctions. The input generating device generates a controller input signal by using the sensor data collected by the data collection device and provides the controller input signal to the xerographic imaging system to control quality of the xerographic images when the determining device determines that the at least one sensor has malfunctioned. A method for controlling quality of a xerographic print after malfunction of a quality control sensor is also described.
