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.
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.
