Some of Binden’s returns also show that they were scanned on a Xerox 7655.
Right. Except for the White House long-form and COLB, the documents created within the same month as the Obama long-form scan all use the same protocol indicating the Xerox machine as the PDF producer, which is a different protocol than all the other scans I can find from 2009-2013, including the long-form and short-form BC’s.
