摘　　要：为减小激光打印机的几何误差,根据实验得到的设备像素尺寸与其打印位置的关系,推导了目标打印位置随像素尺寸误差变化的公式,给出了由目标打印位置求逻辑打印位置的流程。在有限多的位置附近测得一定范围内的平均尺寸误差后,用分段多项式求任意位置的尺寸误差。多项式系数则通过函数链神经网络学习得到。根据所求的逻辑打印位置进行打印,最大横向几何误差由1.8%降到了0.2%。To reduce the geometric error of laser printer,deduced formulas for describing how the target print position of a device pixel varies according to its dimension error based on experimental conclusions about the relation of its dimension and position.Using flowchart,illustrated a method for calculating the logic print position when knowing its target print position.After determining dimension errors averaged within a certain range around a finite number of positions,use several polynomials to calculate dimension errors of arbitrary positions.Moreover,these polynomials are determined by training of functional link neural network.By printing at the calculated logic positions,maximum horizontal error reduced from 1.8 % to 0.2 %.
