FS-6025 jamming no wast toner bottle

[Haggy0310]

Hi guys,

I am pretty new to Kyocera. Try to fix a FS-6025 with an odd problem. Copy or print jams all the time in the middle of the fuser unit.
Remove paper close door. Machine showes wast toner bottle missing. Open close front door starts to print again. Same procedure.
Replaced exit unit. fuser unit all boards, Developer and drum, checked all sensors OK. Any ideas much appriciated.
Thanks
