Printer not scanning to email

The saga of the printer continues: I tried to scan to my email this morning, but when I clicked the email button, the screen said “Email Gateway is not responding. Contact Administrator.” I turned it off and turned it back on, and made sure the yellow cable was properly connected. I waited an hour. It still says the same thing. The printer is the HP LaserJet M3035xs MFP, G190007.

I have emailed IT.
