I've never had it come up even once, so it isn't common and I have no idea if it is just an insignificant thing, or if it means anything.
I wouldn't dwell on it, if it happens again I would call in Xerox to inspect it (Assuming contracted with a maintenance agreement)
If it stays fine after the adjustment I would pretend it never happened and move on with life.
If they were not in the middle I would go find Steve* who works in Accounting and give him <redacted>
You can't trust that guy, he is always causing a ruckus
*It is entirely possible this whole bit should be ignored, if you really do have a Steve in accounting I (think its awesome, what are the odds I could guess that?) apologize for the inappropriateness of the comment
