Hi there and welcome
It is likely the motor is not turning correctly, or the rollers are not picking up the paper correctly.
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
Can you open the printer and wipe down all the rollers, making sure they are as clean as possible, then let it dry for 10 minutes, close it back up and tell me if it now prints better please.
