Thanks guys, Minoltaboss you meant ofcourse the Laserunit and not the Image reader isn't it?
Anyway went there and found the grid extremely dirty cause they are doing some decoration work in that office, lots of dust and paint fumes. BTW the drum is only 60K old as the Grid. Cleaned the grid and will see what happens in the coming days.

@ Minoltaboss: any relation with the former KN company?
