Tony,

I don't have a 7475 in front of me, but here's the steps to
initiate the self-test:

1. Turn off power
2. Load pens
         Pen 1 = Black
         Pen 2 = Black
         Pen 3 = Red
         Pen 4 = Green
         Pen 5 = Blue
         Pen 6 = Violet
3. Load paper
4. Hold P1 and P2 down
5. Turn on power
6. Release P1 and P2 when plotting begins


Cheers,

Dan
