Tell him that he is not alone. The theatre I am currently at smartly avoided installing SDDS. What he probably needs to do is have a tech come in and change out the LED arrays inside the reader.

I emailed some info directly to you. As I said in that email:

It is important to keep in mind that CCD output gain adjustment alone may not resolve the problem. In fact, it may only hide the real problem temporarily until the LED's age further. Your best bet for a properly operating unit is to have a technician experienced with the SDDS equipment do a complete reader alignment. This will entail
aligning the light pipe outputs to the CCD's as well as the timing disk on the back of the sprocket with its emitter/detector assy. Keep in mind that the unit should have, at the very least, a yearly alignment as they are notorious for falling out.

Good Luck!
