I have a Marantz CD6007 that will play commercially manufactured CD's but will play CD-Rs only about 10% of the time. I have read that CD-Rs are only about 40% reflective as commercial CD's. These CD-Rs play 100% of the time in my $40 Sony DVD player. From what I have read, I need to turn up the intensity of the laser a little bit, so it can read a CD-R. The laser has this number on it "EP-C101". Several videos show a Pot on the laser for this adjustment, but I don't see one on this laser. Some videos suggest that the Pot might be on the circuit board that the ribbon cable to the laser is attached. Don't see a pot on this board either. Can someone advise me how to adjust the laser on this CD player?
You are correct that CD-Rs are less reflective than commercially produced CD's but that may not be the reason your unit doesn't always play them.
Could be as simple as the media quality / compatibility or the condition of the CD burner, or even the speed at which the CD-Rs were burned.
Diagnosing and repairing / adjusting a CD player requires the service manual, the proper test equipment, and the proper training, plus experience.
Otherwise it's best not to attempt it as it's easy to do more harm than good, and possibly end up with a unit that doesn't play anything.
