My wife’s old Samsung S5 would not work with our MG7520 via NFC. I heard it was a poor phone antenna. We just got new S10e phones and I tried printing photos the other morning via NFC and it worked great!
Later that evening I bragged up and went to show off the feature to a visitor, but though the NFC connection was made, only blank 4X6 pix came out! That was embarrassing! It still kicks out blanks after a dozen tries with both phones.
Why would it work in the morning and then not again? Do I need to reload the Selphi apps on the phones, or is the glitch in the printer?
