Hi...

I found this in one of the posts...

For the future, since every board is a different color... Use a piece of white copy paper on the board and crank the head down and measure the Board Sensor. A 156 is perfect a 90 is a dirty window.

I am getting a 14 - 12 (it starts at 14 and goes down to 12).

What is that telling me?

Thanks...
