The issue is that the client operating system doesn’t have a way to validate Xerox self-signed/self-generated certificates with an external CA (Certificate Authority) like Verisign for example. New operating systems now have features that ‘flag’ this as a concern and display a security alert when accessing the device from a web browser or using bi-directional features in print drivers. The solution is to download the ‘Generic Xerox Trusted CA Certificate’ from the device and identify it as a ‘Trusted Root Certification Authority’ to the client operating system.
Specific Instructions for your device model can be found in the System Administrator Guide by going to Xerox Support and inputting your specific Xerox product, then choose Documentation and search for the System Administrator. You can also use the Online Support Assistant tool by going to Xerox Support and inputting your specific product and selecting Support from the menu, then typing in your search term.
