Copy looks like it has dark waves . I checked dev roller and those waves came from dev roller indeed. I cleaned only the roller had some small improvement. Do i have to clean and remove all toner from dev unit or have to look at somewhere else?

I hope the devunit /roller has got a life span expressed in terms of no. of copies. Find that stats from the manual and compare with the actual copycounter to judge if time is not up for replacement.

This wave from the dev cylinder happens when a different toner is loaded, solution = adjust by lowering the doctor blade until the wave is gone...
