Morning, these models are the worst models I have in the fleet, I hate them! I haven’t seen this before but it looks like the the transfer roller is causing the issue but if this has been changed, is this being caused by the fuser, only it looks like the distance is about right if the lead edge of paper is in the fuser? I chased intermittent creasing paper for months (only on A3 paper) and it turned out to be the fuser. I had discounted the fuser because it looked brand new but that was the cause! Good luck!

Try with different fuser transport speed.
