The syncronicity of feeding mechanism and drum is lost. The sound was the jumping of the toothed belt.
Seems that the stripping finger or the blower is stuck in the clamp mechanism blocking the drum moving forward.
This problem can be caused by a worn rubber reel. So the stripping finger is not lifted enough any more.
Remove the back cover. Locate and check the rubber reel running at the excenter of the print drum.
Do not turn the machine in forward direction till this is solved. Else you may damage the clamp mechanism.
To restore synchronicity you have to remove tension of the toothed belt by loosening the 3 screws around the paper feed clutch. Turn the mechanism clockwise and fix a screw temporarily in this position.
Now it should be easy to lift the toothed belt over a tooth, moving a bit, and so on.
You have to move the drum driving mechanism till the sensor there meets the small hole. At this position the sensor at the paper feed mechanism should match the cutted semi-circle. Synchronicity restored. Restore tension at thoothed belt and test.
I had this problem too: just unlock the hook under the drum; disengage the drum then pull out the drum; then check the home position if not in position open the behind cover, pull the belt until you get the puller to the home position. You will get the same problem if you will not put the main drum puller to the home position. firstname.lastname@example.org
