Title:
【発明の名称】複写システム作動方法
Document Type and Number:
Japanese Patent JP3380821
Kind Code:
B2
Abstract:
A method of controlling voltages (Vddp,LP,Vbias,Fig. 4) in a latent image development printer (1000). The method comprises deriving first, second and third values, biassing a developing apparatus (1037) to a first voltage (Vbias), charging a substrate (1010) using corotrons (1022,1022) to produce a second voltage (Vddp), such that the difference between the first and second voltages is equal to the first value, and discharging selected areas of the substrate (1010) using a laser (1032) to produce a third voltage, such that the difference between the third and first voltages is equal to the second value, and a ratio between a function of the second voltage and a function of the third voltage is equal to the third value.
