Hi there and welcome
Please follow the steps on my link below which will take you through all the areas a paper jam can occur and how to clear it
Let me know please how you go
ok sorry you feel that way about me,
If you see no paper then it is not going to be caused by paper but a sensor.
Can you please remove the power to the printer (so unplug it from the power socket).
Then wait 10 minutes, connect the power again to the printer, turn it on and tell me please if it is now operating correctly.
Let me know the results please
