Weird, you even put in bold type that you had the General release, which is absolutely not the one I linked to above.
Especially weird since mine running the 60.001.13.000 SMPR3 version doesn't fail with a Qualys and did on the GR that you posted you are running.
I guess you are going to have to call Xerox and get them to to figure out how your printer is different than the others. Or just submit a report here.
The latest firmware is already installed.
Latest version is here
I'm facing the below issue with the newly installed xerox WC3345 Printer and firmware level is 60.001.13.000.
any patches or fix is available on this issue.
