how do test prints look?? have you done gain auto adj page 13-12 of manual and I am sure you have cleaned the CIS... also if in a dirt place sometimes the Laser needs to be cleaned..

Thanks for your info,Ill try the gain auto adjustment next week the test prints look ok but to be honest I dont know if I left it long enough between prints I didnt look at the laser because its only the first copy then perfect it just feels like optics dont know why

Shading adjust can cause this. So can developing, if you have a scrap of paper or some other contaminant in the developing unit.

I have tried different drum and dev unit as in the past had odd problems down to dev roller what I'm trying to avoid is buying a scrapper just to swap boards fibre optis etc.

Transfer roller? Remove and clean with cold water.
Since you eliminated the drum & dev (most common for light areas), transfer roller may be the issue. If not, that leaves the image unit (not likely) and the fuser - but my limited exp is fusers leave dark or "flaky" areas - not light.

light band
Check the laser unit, if the laser unit shield glass is dirty it will cause light copy/print.
