I am not sure what you want to know. I can talk you
through taking the CX
engine apart, and what the 'DC contorller board' -- the print engine
cotnroller with a 7811 microcontroller and a gate array that controls the
laser intensity does. And how the various PSUs, laser scanner, etc work.
Sorry for bothering you, I was just out of curiosity, I remember having
read this great work and wanted to remember. Great job you did,
