First check your power voltages.then check your primary charging of black drum
looking at your samples, classic fusing issue, but you say you have replaced the fuser.
Are you using genuine toner?

I've seen similar on a C5035, printing on A3 Glossy paper.
Temp. of the fuser dropped while printing, so first copies came out perfect, then fixing temp started dropping until it was to to low to properly fuse the toner to the paper, next copies started giving smudges...
You can see the temp. dropping in Servicemode, i think it was in DISPLAY-ANALOG-FIX-* but not sure...
I've set the papertype to HEAVY and issue was solved..
