[Misc] 1050 pro strange second side..

[Michko]

Hey.

I can't find out whats wrong with this machine.... A college did a pm service 750k a week ago and now it looks like this...
I changed separations unit and cleaned everything.

You can already see a little bit of this on the first side but not like this....
It gets better if I change paper weight to higher and yellow paper embossed. But nothing if I change power settings in service mode.

Looks like either a dirty grid/charge wire or needs a new drum. (I take it the tramlines are in the feed direction?)

[MAJSTOR]

it seams that drum has a few scars, but real problem is in the corona/greed. you can clean it or better change it. kind rgds

yes it is....
but grid and corona are changed a week ago when the service was made. Even developer and drum was changed...
