An understanding of the mechanics of paper separation is very importan
t to the design of reliable photocopiers, and in this paper a model is
developed to simulate friction feed paper separation. The importance
of such system parameters as roller acceleration and compressive load
is demonstrated. The variability of friction coefficients is shown to
have a significant effect on feeding reliability. Experimental data ar
e shown to be in good agreement with predicted results. Recommendation
s are made for the design of reliable friction feed paper separators.
