HT: Kevin Vicklund who first raised the Xerox WorkCentre as a possibility.

But based on my poking around, I would put money on the White House having a Xerox WorkCentre color copier/scanner with a “scan to email” feature, rather than anything attached directly to someone’s Macintosh.
The POTUS tax PDF was created on a Xerox WorkCentre 7655 and JPEG shows graylinear just like the Xerox WorkCentre 7655 scans I obtained. So again, we now have a likely candidate for the actual device used. The VP Tax return also shows a 7655 workcentre but it has not been touched by Preview and shows PDF 1.5 encoding, and JBIG2
Given that the SCOTUS PDF was created on a 7655 WorkCentre, I tentatively conclude that the device used to create the Whitehouse birth certificate PDF is a Xerox WorkCentre 7655
I checked the Xerox site for MRC and JBIG2 encoding in the specifications
- WorkCentre™ 7328/7335/7345/7346
- WorkCentre 7755/7765/7775 – Xerox
- WorkCentre 7425/7428/7435 – Xerox
- WorkCentre 7655/7665/7675 – Xerox
Improved scan export compression (MRC, JBIG2) reduces traffic on the network and speeds your documents to their destinations.
