tested on pc version Adobe Indesign CS6 8.1

All imported pdf color scans from Xerox WC78xx copiers fail to create a new PDF in Indesign when using 'High quality Print' setting in Indesign PDF preferences.
The only workaround is choosing convert to CMYK (or press quality) in Adobe indesign pdf preferences.
Xerox now knows about this (I contacted them as first) but they say it's not their fault, Indesigns handels their scans wrong.

my Xerox contact is Bart.Knops@xerox.com

Please help ASAP, as this affects all users of indesign with Xerox machines (a lot!)
