Hi,
I can give you the meaning of the code, but I'm sorry I can't necessarily "oasq" as the possibilities are many. The code means that when the copier went through its initial checks to make sure it was ready to perform properly for you, it "detected/percieved" that the scan lamp that illuminates your documents could not reach a brightness that would allow the copier to provide you with the copy quality you would expect.The copier has many ways of compensating for wear and age. Like turning the voltage/ power to the scan lamp UP .The copier has compensated as far as it can. The scan lamp is fried or close to it.What you must understand is that there are MANY variables that may give this code. The most likely is indeed the scan lamp as it is like any other lightbulb it weakens with time. The part # is FH7-3314-000. Now this may help. What happens when you first turn the copier on it does many self checks. One is to push the scan lamp to it's home position which of course is to the left.The lamp(flourecent)  turns on and shines onto a white plate called the "standard white plate". The copier uses that as the standard for what white is and calibrates itself from there. "IF" the standard white plate is dirty (yellowed from time or dirt) then the copier knows no better than to turn up the power to the lamp as it is looking for a reflection that is bright enough to make good copies. If the plate is dirty then the lamp cannot overcome the dim reflection. So, power off the copier, clean the mirrors with a soft cloth and mild cleaner (water and Windex) and clean the underside of where the the lamp sits when it is at rest/"HOME position. What I mean is, when you first turn the copier on, and the document feeder is in the up position, you will see the scan lamp come on. Observe closely the area that it is "illuminating". THAT is on the underside of the far left and also needs to be cleaned.Just make sure that when you seek to clean stuff that the copier is OFF, for YOUR safety. So, we have a code that means the lamp can't get bright enough, and it may be bad.Or , the white plate may be dirty and the lamp can't get bright enough. The mirrors that you see (and there are 3) could be dirty and cause the light to be bad. Those are the basic, most common causes. I hope I helped you, I know I have explained the code and the most common causes. If I had a screwdriver that would reach you I would use it. :-) Pleasse let "oasq" know I helped to some degree, The really cool thing would be if you and I did indeed save you an expensive service call. Take care.  SPINAL
