"Checking Paper" error on 9125e

I received a new HP OfficeJet Pro 9125e today, 01.31.24.  In trying to set it up, it continues endlessly to "check paper."  When I try to get assistance, I am asked for the S/N.  I quote the S/N from both the box and the rear of the machine, yet I am told that the S/N is incorrect.  It wold be nice if someone, preferably a human, would contact me to help.  Thank you.

The S/N shown is:  TH49JG604K.  On the rear tag and the box.
