False OPC low message on Xerox and Mac.

Lately, we've seen several occurrences of a problem with Xerox Phaser 6350 and 6360 series print drivers on Mac OS/X 10.6 and 10.7.

The driver causes a false message to display that the OPC or Optical Photo-conductor unit needs to be replaced.  The message is displayed only on the Mac, not on the printer.  Having checked the supplies via the embedded web page or the supplies status info on the printer, it shows the correct status is not low or needing replacement.

We have not seen this problem on Windows systems.

I was confused the first time I heard this from a client because Xerox does not use the term Optical Photo-conductor.  That was my first clue. Xerox refers to this consumable item as an Imaging Unit.

In an attempt to correct the false message, we deleted the driver and all files related to Xerox on the Mac.  Then we re-installed the driver from a fresh download.  This made no change or improvement.  The false message was still there.

With this false message, the printer will function normally.  The only effect is the annoyance of a pop up message.

At this time, we have no solution for this problem.  We expect Xerox will issue an update to the printer driver at some point.

Hang in there for now.
