kyocera mita KM 3050

[Renuen]

I have a problem with a Kyocera KM 3050. I have a two centimeter film toner points horizontal. 8 cm from above.

The machine:

Life count 570170
maintenance count 170000

I switch the transfer roller, no chance
corona, no change

I use a new developer, the points are darker :confused:

I remove the developer and use the old one

The points are very small and anemic

Thank you very much for any help :)

The spots that you are looking at are probably arc marks between the primary and the drum. You'll need to replace the drum unit to resolve this issue.
