Take the following into account when installing the high voltage power supply board.
- Install the board so that the transfer pressure spring [A] firmly contacts the secondary transfer output terminal [B], making sure that the spring does not buckle.
- In B/W mode, print out a test pattern on two sheets of A4 paper consecutively. Then, make sure that there are no abnormalities in the image.
