Installing the board
There are two basic interface board designs. These boards differ with respect to how the frame ground (FG) wire is attached. This slight difference changes the way the boards are installed in the printer, but does not affect the operation of the interface in any way. Look at the following illustration to see which type of interface board you have and then follow the installation procedure for that type of board.
