Abstract

Systems and methods of determining a predicted usable life of components, such as a photoreceptor, associated with an imaging device. The systems and methods include a power source configured to increase an electric field across the photoreceptor. A sensor or array is configured to detect charge deficient spots (CDS) in a charge transport layer (CTL) of the photoreceptor as a result of increasing the electric field. The systems and methods are configured to determine the predicted useable life of the photoreceptor based on the detected CDS. The systems and methods are further configured to output a report of the estimation. The estimation is conducted at fixed or variable intervals throughout the life of the photoreceptor and/or imaging device.

Claims (28)

1. A method of determining a predicted useable life of a photoreceptor of a device that performs imaging operations for one or more customers, the method comprising:

increasing, by the device, an electric field across the photoreceptor subsequent to the device performing one or more imaging operations of a customer;

detecting, by the device, charge deficient spots (CDS) in a charge transport layer (CTL) of the photoreceptor as a result of increasing the electric field;

detecting, by the device, a voltage applied to the photoreceptor at which the CDS are detected;

determining the predicted useable life of the photoreceptor based on the detected voltage; and

updating the predicted usable life of the photoreceptor at a plurality of intervals during a life of the photoreceptor.

2. The method of claim 1 , wherein the charge deficient spots (CDS) are detected using a full width array (FWA).

3. The method of claim 1 , wherein increasing the electric field across the photoreceptor comprises increasing a voltage on a surface of the photoreceptor.

4. The method of claim 1 , wherein determining the predicted useable life of the photoreceptor based on the detected charge deficient spots (CDS) comprises:

detecting a number of the CDS that appear as a result of increasing the electric field; and

determining the predicted useable life of the photoreceptor based on the detected number of CDS.

5. The method of claim 1 , wherein the charge deficient spots (CDS) are detected across a length and circumference of the photoreceptor.

6. The method of claim 1 , further comprising providing an output report of the predicted usable life of the photoreceptor.

7. The method of claim 6 , wherein the output report is provided via a graphical user interface (GUI).

8. The method of claim 1 , wherein the output report is provided to at least one of the customer or a supplies ordering system.

9. A system for determining a predicted useable life of a photoreceptor of a device that performs imaging operations for one or more customers, the system comprising:

a power source configured to increase, by the device, an electric field across the photoreceptor subsequent to the device performing one or more imaging operations of a customer;

a scanner configured to detect, by the device, charge deficient spots (CDS) in a charge transport layer (CTL) of the photoreceptor as a result of increasing the electric field; and

a processor configured to detect, by the device, a voltage applied to the photoreceptor at which the CDS are detected, determine the predicted useable life of the photoreceptor based on the detected voltage, and update the predicted usable life of the photoreceptor at a plurality of intervals during a life of the photoreceptor.

10. The system of claim 9 , wherein the scanner is a full width array (FWA).

11. The system of claim 9 , wherein the electric field across the photoreceptor is increased by increasing a voltage on a surface of the photoreceptor.

12. The system of claim 9 , wherein the processor determines the predicted useable life of the photoreceptor by:

detecting a number of the CDS that appear as a result of increasing the electric field; and

determining the predicted useable life of the photoreceptor based on the detected number of CDS.

13. The system of claim 9 , wherein the charge deficient spots (CDS) are detected across a length and circumference of the photoreceptor.

14. The system of claim 9 , wherein the processor is further configured to provide an output report of the predicted usable life of the photoreceptor.

15. The system of claim 14 , wherein the output report is provided via a graphical user interface (GUI).

16. The system of claim 14 , wherein the output report is provided to at least one of the customer or a supplies ordering system.
