Take the following into account when installing the high voltage power supply board.

  1. Install the board so that the transfer pressure spring [A] firmly contacts with the secondary transfer output terminal [B], making sure that the spring does not buckle.
  2. In B/W mode, print out a test pattern on two pieces of A4 paper consecutively. Then, make sure that there are no abnormalities in the image.
