Transfer corona is bad or too close to drum.

Re: ir 5000

did you reset the counters for corona/corona wire in service mode? If you forget this, the mashine thinks: "hey, there are really worn corona wires... i will give it an extra boost"
The result is, that the mashine fires up the coronas with all her might and this leads to spark impact of the drum surface.
