Current monitoring to detect photoreceptor scratches |
摘要 |
A method monitors an electric current supplied to an electrostatic brush within a printing device. The electrostatic brush contacts and cleans a photoreceptor surface within the printing device. The method records a current spike pattern of when the electric current exceeds a first current threshold during the monitoring; however, the method will stop operations of the printing device if the electric current exceeds a second current threshold that is greater than the first current threshold. Further, the method can determine whether a scratch is present on the photoreceptor surface based on the current spike pattern. |
