A method including: (a) positioning a hollow substrate having a first end and an open second end in a solution, wherein the open second end is submerged in the solution, wherein gas is present in the hollow portion of the substrate between the solution and the first end, thereby defining a quantity of trapped gas molecules; (b) removing the substrate from the solution; and (c) changing the quantity of the trapped gas molecules by (i) withdrawing a portion of the trapped gas molecules, or (ii) introducing additional gas molecules into the hollow portion, wherein (i) and (ii) are accomplished through the second end of the substrate, thereby controlling the pressure of the gas in the hollow portion.

Substrate interior pressure control method

This invention discloses an apparatus for holding and transporting a hollow flexible belt throughout a coating process. The apparatus includes a spring and shaft assembly which is placed into the hollow portion of a seamless flexible belt. The spring portion of the assembly until it is transformed into a belt carrying chucking device. The chucking device is then attached to a mechanical handling device, and the the belt is transported through the dipping and coating process. This allows the belt to be transformed into an organic photoreceptor. The chucking device and flexible belt are then removed from the mechanical handling device, and the chuck is removed from the inside of the photoreceptor.

Spring and shaft assembly for handling and dipping flexible belts

A method for forming an electrostatographic photoreceptor includes the steps of selecting a desired sensitivity range and a desired light intensity for a photoreceptor and forming the photoreceptor having the desired sensitivity range and desired light intensity. The photoreceptor includes a supporting substrate and a photogenerating layer including a charge generating material, formed by coating the photogenerating layer on the supporting substrate. The charge generating material is formed by a process including dispersion milling a photogenerating material for a selected period of time, selected in accordance with the desired sensitivity range and the desired light intensity, to adjust the desired sensitivity range and desired light intensity of the photoreceptor.

Tunable imaging members and process for making

This invention discloses a method of holding and transporting a hollow flexible belt throughout a coating process. The method includes placing a spring and shaft assembly into the hollow portion of a seamless flexible belt, and expanding the spring portion of the assembly until it is transformed into a belt carrying chucking device. The chucking device is then attached to a mechanical handling device, and the the belt is transported through the dipping and coating process. This allows the belt to be transformed into an organic photoreceptor. The chucking device and flexible belt are then removed from the mechanical handling device, and the chuck is removed from the inside of the photoreceptor.
