Versant 280, error 076-101 not found?

[Rusty.Harris]

Only does it every 800-900 copies. Can't locate the RAP in the machine, GBC punch, decurler,
Inserter, finisher, HCF.
Any ideas? Looks to only do it when duplexing

Apparently, the NVM value 765-523, was set at the factory to 1, and should be 0
Once the tech changed it, problem went away.
