Hi..

I have to change some parts for better results.
That parts are..

2.cd-rot unit toner fully cleaned with blower changed with new toner.
3.new fuser film .
4.laser dust glass clean with smooth cotton.

But no result..???

I can make prints and scan it will comes very clearly..
But only copies are very lightly on upside only..
