Separation Static Eliminating Bias PCBThis circuit is controlled by two signals (Figure 4-611) from the DC controller PCB,and generates the separation static eliminating DC bias and the separation static elimi-nating AC bias for application to the separation static eliminating assembly.The voltage applied to the separation static eliminating assembly is turned on and offby the separation static eliminating DC bias drive signal and the separation static elimi-nating AC bias drive signal. The level of the biases (both AC and DC) is kept to a specif-ic level.The DC controller PCB generates the separation static eliminating AC bias drive sig-nal to suit the type of paper and the conditions of the environment.Figure 4-611CHAPTER 4 IMAGE FORMATION SYSTEM4-33Separation static eliminating high-voltage PCBDC controller PCBSeparation staticeliminating biasgeneration circuitIntermediatetransfer drumSecondarytransfer beltSeparationstaticeliminatingassemblySeparation static eliminating AC bias driveAC+DC (positive)Separation static eliminating DC bias drive signalDownload free service manual at http://printer1.blogspot.com
