Let it run like this for a while, more than likely it's an auto alignment process. Once started, you can power off and power back on and the printer will start it right back up until finished.
It's a bit confusing as no message shows on the screen. If it does this for longer than around 15 minutes then there might be another issue.
The issues of the head moving back and forth, no ink coming and no paper moving most often are the auto alignment process. There is no rhyme or reason when this process will start.
