Loose pieces in Printer (Pro 300)

[Udriku]

I received a Pro 300 today in the mail, used from eBay, and when I turned it on, I got Error Code 5100. I was supposed to check if there are any foreign objects in the printer, and I found two white plastic parts. I think they may have come loose during shipping. Does anyone know what those are?

Maybe you bought the printer this person had back in July?

If it came broken, you can put in a return on eBay, even if the listing said "No Refunds". Get rid of this dog.
