Latest Patents
Among his latest patents, one is titled "Electrophotographic control in imaging devices, including sensing current between a developer roll and drum pertaining to current of a latent image and a paschen breakdown." This invention involves an imaging device that utilizes a developer roll to provide toner to a photoconductive drum, which develops a latent image for transfer to media or an intermediate transfer member. The device features a power supply that communicates with a controller to set relative voltages on the developer roll and drum. During the toner transfer process, the device determines the current between the developer roll and drum, allowing the controller to adjust the charge and mass of the toner accordingly.
Another significant patent is "Compensation for deficient charge roll in an imaging device." This invention describes an imaging device that includes a photoconductive drum charged by a charge roll and opposed by a transfer roll. The drum is biased to a negative voltage, and the controller switches the bias of the transfer roll to a positive voltage. By determining the delta in charge before and after the switching, the voltage on the charge roll can be boosted to ensure proper imaging, even when the charge rolls are deteriorating or defective.
