Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
How new is the printer? if it has worked before this in its current installation, that makes the object being 'shipping tape' somewhat less likely.
Sometimes pulling the paper out can disorder or even 'break' the printer, so when paper is jammed in a printer, it is as well to follow procedures given for your printer, exactly.
The question is: Was that indeed shipping tape, do you think, or was it something else?
And, does the printer feed in paper, after the paper has been reloaded into the paper tray, and not more than 30 sheets loaded, and the printer is also (while the paper is being reloaded carefully) turned Off for at least 5 minutes ?
