Haha..... Birth Certificate....

Hopefully you can find the "birth certificate" for that machine, the paper that comes with new machines from Ricoh that shows all of the adjustments from the factory. If you can find that, I'd recommend you check that the adjustments listed there are correct first before you try any other new adjustments.
(It sounds a little bit like somebody did a memory reset to the machine when one was not needed. I'm probably wrong, though.)

yes that's what Ricoh calls the SMode settings sheet for the machine.. it used to be stored under an inner cover on the front side of the machine..

it IS actually called the " Birth Certificate "

In other words you actually followed the service manual directions for replacing the laser diode unit. That must have been a radical concept for you.
