Hi dupecoop
Thank you for using the Xerox forum.
I would suggest that you review the following "To find a specific fault code, try our Fault Code Search." on the ColorQube 8870 Support & Drivers site.
If that does not resolve your issue you may consider contacting our specific product support experts at the following link:

I'm getting error code 91,720.00:9875 on my Colorqube 8870.
Any idea what might be causing that? I did a search came up empty.
