Paper Abstract

A color copy may exhibit more severe curl than a black-and-white copy due to profound shrinkage difference between multiple toner layers and the base paper after the fusing process. An untreated curled copy may cause paper handling problems and it is unacceptable to customers. This paper analyzes factors contributing to copy curl developed after the fusing process with an emphasis on the stiffenss and shrinkage interactions between the toner layer and the paper. Specifically, a bi—material curl model of toner— paper composite is formulated in terms of ratios of toner/paper thickness, modulus of elasticity and expansion coefficient. The curl model regards the temperature and moisture changes as the driving forces for the curling of a fused copy. Besides predicting away—from—image and toward—image curls, the model can be used to determine requirements of toner modulus,layer thickness and fusing temperature to meet specified curl limits of fused copies.
