Hp Smart Scan To Email Not Working, Hello! I'm having an issue with the Scan to Email feature on this printer. You may be prompted to configure email settings, which usually involves entering your email account information In the HP Smart app, go to the printer settings and look for Scan settings. You may refer to this document - HP Printers - Scan to Email Cannot Access Some email account service providers, such as Google or Yahoo, block access by third-party apps for security reasons. I use HP Smart to scan documents. Google Info. HP downloaded scanning software. Use our HP Smart app to resolve scanner issues. I've already hard re-booted the printer, but that didn't work. Scan to email is not working. Says password is wrong in hp printer, but nothing was changed.
