Abstract

One of the primary components in a Xerox copier is the print engine. The center of this engine is comprised of a photoreceptor, which is a roller/belt module mounted to a frame. The belt revolves around the module acquiring and transposing toner to sheets of paper as they come into contact with the module. The initial design of these modules can often lead to registration and print quality problems later in the assembly and application phases of design. The current analysis procedure includes lengthy commercial FEA packages that require high designer investment. For this reason, many new ideas are never given the opportunity to develop. The implementation of a low investment analysis step which is designed to reveal problems with a design's general formulation could save the corporation both time and money. The means of statically approximating designs before they are modeled in commercial FEA packages could allow for more module configurations to be analyzed and considered. This low investment means of approximation has been developed here. A user friendly Excel spreadsheet based generic photoreceptor module analyzer is derived, explained, and correlated in the ensuing analysis. Although approximate, the ability to compare designs and choose the best one for the application makes this analysis successful. The generic modeling capability is automated such that user interaction is minimal and navigation is relatively simple. Also included in this thesis is a step by step instruction set for inputting module parameters and running the program. A Nastran FEA model was constructed and correlated to this solver, which was shown to retain the correct order of magnitude (micron level) and overall deformation shape. Future adjustments and other software capabilities are also discussed.
