That is exactly why companies should all pay a little more and buy a Konica Minolta Copier, the HDD security is built into the entire line. ISO 15408 EAL Level 3 architecture. 128 bit AES encryption for any temporary data stored on the HDD, and HDD Overwrite Sanitization to DOD and NSA standards and more.
Of course as a customer you have to specifically ask your tech or sales person to turn that on. Most don't.
(Yes I work for Konica Minolta) 
Not too many of my customers in past have been too concerned with the security of these devices, with the exception of Defense Contractors, but in the future after this report, I am sure that there will be a greater awareness.
I have a few companies that will not let us take a copier without removing the HDD first and leaving it with them.
