The headline of the HN article is a bit misleading.

"using a forensic software program available for free on the Internet, he ran a scan - downloading tens of thousands of documents in less than 12 hours."

Since he had to use special software to extract the files, it looks like the software deletes the files, but not securely. Basically, it uses 'rm' instead of 'scrub'.

As explained below, storing scanned pages temporarily is good when photocopying (or faxing) multiple pages.

Also, the creator of the software mentioned (securely wipes photocopier harddrives) is a very smart marketer. The article is basically an advertisement for his software, "INFOSWEEP," and he's the one who showed the journalist this vulnerability in the first place.
