DI-850 SC 29-04 / 26-03 and PM

[potro_salvaje]

I recently bought this machine to average use, works great at first, but now I get these two errors repeatedly, starting and stopping the machine and operate normally, am very concerned about this because I have no manuals, would greatly appreciate any ideas that are .

I also lately appeared PM preventive maintenance call for service

29-04 is gamma correction error & 26-03 is seperation corona error.
I would at least replace the coronas and clean the ID sensor under the cleaning unit.
At most I would do the full PM, just so you know the image area is all new.

Thanks for the quick response, 26-03 is exactly as I say and already fixed.
And I think the PM is because the cycle of copies is 500 K and the machine currently with 535 K, in my old machine just to reset the counters, in this type of machine to do the same?, I can reset the counter ?
