Figure 26. High-voltage power supply block diagram 78 Chapter 5 Theory of operation High-voltage power supply circuit The high-voltage power supply circuit applies a high-voltage bias to the primary charging roller, the developing cylinder, the pre-transfer upper guide, the transfer charging roller, the separation static charge eliminator, and the pressure roller through the ASIC (IC 202), according to instructions it receives from the CPU (IC201) on the DC controller PCA. The high-voltage power supply circuit also detects the toner level.
