MGI DP60 PRO : marks

Hello everyone,
I've a big printing problem with a MGI DP60 PRO. In fact, after a paper jam the cleaning blade of the belt cleaner unit was reversed, after cleaning and refitting I had 528mm horizontal spots each 3 sheets so I replaced the Intermediate Transfer Assy + Belt Cleaner Unit with another functional, now I have spots all over the width of the sheet every 95mm that normally should be the 2nd Transfer Roller, I did all the procedures but nothing, after disassembly I noticed that the plastic piece "TRANSFER FULCRUM BEARING" ref. 65AA 4507 0 at KM is broken which explains the pb so change by another one but the same default is always present ... I do not know what to do ..
Need Help please!!

 

Hi, could you attach some pictures of printed paper?
