Note

The high-voltage power supply contains a flyback transformer to generate high voltages for the primary corona, transfer corona, and developing bias from the 24V section of the DC power supply. Digital signals from the DC controller activate the high-voltage supply. A print density dial is located on the side of the high-voltage supply, which is accessible by the operator. This dial comes in several different colors.

The high-voltage power supply has been revised several times. The original part number was RG1-0213-000, which was revised to -070 and is pictured in Diagram 125 above. A second version, always used in CXD printers and later CX models, is RG1-0469-050. This version has a different cover and is also pictured above, labeled 'Revised Version'. The HP service manual lists the part number for it as RG1-0649-000. We believe that HP made a typographical error and the correct part number is actually RG1-0469-050.
