Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
I think that it is likely that the printer appears to be only scanning, but not printing out what it has scanned (i.e. not completing the full cycle of the task of scan-and-print-copy) owing to some defect of the printing system.
Check whether there is blank paper loaded in every tray.
Check whether the printer can do a test print (whether self-generated, or sent from the computer.)
Let me know and I will help you further.
