The question whether or not the number mangling in scanned documents only occurs at Xerox devices seems to have been answered. I got an eMail of a Brother customer telling me he's able to replicate the issue using my test number sheets on a Brother MFC-9140CDN. He attached the outcoming scan and indeed, there is at least one 6 substituted by a nice, clean 8.

Edit: Brother replied and stated that their devices are not affected by number mangling. At first glance, the Brother MFC seems to substitute a lot less numbers than the Xerox machines. Of course, as I haven't been able to reproduce the error on the machine myself, and additionally, the device ID is not shown in the PDF (there only is to be read “Paperport 12”), so I can't really tell where and how the data has been processed, so please take the information as hearsay. Also, we can never be sure the mails I get are part of some spin doctoring campaign, so be suspicious. I'll be adding potentially affected devices to my “hear-say list of affected devices” though.

Whats more, until now it looked like the newer Xerox devices (WorkCentre 78xx) would not be affected. Unfortunately, I may have to destroy this illusion as I got an email from someone familiar with the topic, telling me that one of his customers is able to replicate the problem on a bunch of eighteen 78xx machines. However, this is no real confirmation at all as I haven't seen any scans of these. Also, I'm investigating what particular 78xx devices are affected.

Next thing: Xerox seems to be telling their support right now. Thus, by someone saying he is xerox support employee (I can't verify this) I got a list of potentially affected devices as Xerox seems to have investigated theirselves. Let's cite the list:

• ColorQube 87XX / 89XX
• WorkCentre 57XX
• WorkCentre 76XX
• ColorQube 92XX / 93XX
• WorkCentre 58XX
• WorkCentre 77XX
• WorkCentre 5030/5050
• WorkCentre 6400
• WorkCentre 78XX (there is something interesting here: I'm getting emails that the 7855 model, unlike other models, does NOT give any warning about character substitution when you select “Normal” on the control panel of the machine.)
• WorkCentre 51XX
• WorkCentre 7220/7225
• WorkCentrePro 2XX / BookMark 40/55
• WorkCentre 56XX
• WorkCentre 75XX

As well: Take it as hearsay. Imagine that Xerox could have scanned the list on one of their own devices.

Edit: Xerox has been preparing some Q&A sheets, have a look:
