One of our readers, Tomo dropped us a note in order to assist getting the word out on this one as this issue has a potential to be very far reaching into the fields of military, medical and construction to only name a few where lives could be impacted.
It appears there is a possibly long standing issue where copy machines are using software for some scanning features. These features are using a standard compression called JBIG2, which is discovered to have some faults that change the original documents.
Xerox has released two statements to date. If you are interested in the latest info, jump to link two.  
There is plenty of reading on this issue. I wanted to get something out to you as soon as possible. A very good analysis was produced by David Kriesel.  He has been very good at updating that page with consist and relevent links. A job well done by David.
David also provides very good analysis of the feature that is causing the issue with the Xerox Workcentre devices. Those are the devices in his deploy. He cites model numbers in every post and even a work around for those affected by the issue.  It has also been discovered that since JBIG2 is a standard compression software, that other copy machine manufacturers are likely affected. 
Please take this discussion to the forum and share any facts that you can.
