I have a Minolta Bizhub 750. The prints are OK, but the copies appear to have two grey stripes up and on the middle of the page. I have make all the automatic settings * drum peculiarity*, i have cleaned the lens and glasses from the scanner but the stripes are still there. Any ideeas?

I have had scanner lamps fail on these, is it lighting evenly front to back ?

Light seems to be even .I have reduce the intensity of the exposure lamp from Drum pecularity manual from 120 to 80 (min.=77) and the grey bands are almost gone... but I am not confortable with the ideea....
