I don't think there is. The last firmware update for that model was in late 2016 and I don't see any mention of TLS 1.2 in the change log.
bye for now.
Hello mikeyb,
It would be best to speak with a software analyst to see if TLS 1.2 is an options for you. I would recommend contacting your local Xerox Support Department for more assistance. Please call 1-800-821-2797.
We would like to disable TLS 1.0 and TLS 1.1, and only use TLS 1.2
Does the Xerox 7428 WorkCenter support TLS 1.2
Thanks
