I have blowed with compressed air everywhere, cleaned everywhere, still the same.
I stop with that, am going to order the inverter sensor based on the code that points to that sensor.
Really silly question it's not the tray above the output tray in the wrong place blocking the top output area

No questions are silly.
One peculiar observation is that when the print is optimized for speed the paper are just 10mm short of clearing the inverter sensor. When I set that setting to "Normal" and the feed speed go down to a low speed the paper are several cm short of clearing the inverter sensor. And as I wrote in an earlier post, A4 SEF, A4 LEF and A3, all of which have different feed lengths, all stop at the same position from the trailing edge of the paper, despite A3 having been feed twice as long past the inverter sensor with its leading edge compared to A4 SEF. It is almost like I feel there might be a misconfiguration somewhere, dont know if that can be possible at all.
If you wonder about the print already at the top side of the paper it is because I have reused some sheets.
This is how it looks after the machine have stopped with speed set to normal, that is slower print speed than when it is set to speed priority:
Now that I have seen those pics, I can say I have had to pull inverter assemblies before to clean the solenoid (which was causing misfeeds), although not on this model. If you do, make sure the small, short harnessed connectors are seated upon reassembly.
NEVER ASSUME ANYTHING
A correction to my previous post.
It was not the speed/quality setting that determines the print speed and how far the trailing edge is from clearing the inverter sensor, it is the dpi setting which I changed at the same time. However, the connection between feed speed and the lenght missing for clearing the sensor remains, low feed speed and the paper misses with about 25-30mm, high feed speed and it misses by just 10mm.

remove the paper reversal section where the paper gets stuck, it should be a breeze for you now since you have reassembled the fuser unit well; ) and check the rubber rollers that do not touch the plastic perhaps a little deformed by the heat of the fuser, if so you should file around them.
