TLS 1.2 was first released in firmware version 073.xxx.197.28500. However, there have been several releases since then.
As Gabiene stated earlier in this topic, update to the latest firmware here:
Thanks. I have updated the machine successfully, and have now got the TLS Encryption setting, which I have set to 1.2. All seems well so far, and the Office 365 report is now showing TLS 1.2.
Thanks a lot for your help.
Thanks for this. The Workcentre 7855 seems to be different and does not have the TLS Encryption section within Security. See below:
The firmware is 073.040.075.34540, which is the latest. So why can't I see the TLS Encyption section?
