6. DETAILS
When an original is scanned or printed, the data for the job is stored temporarily on
the hard disk for jam recovery. After the copy or print job finishes, some of this
temporary data remains on the HDD at random locations until it is overwritten by
the next job.
At the end of every copy and print job, the DataOverwriteSecurity Unit
automatically writes over unneeded temporary data with random data twice and
with a zero (0) once. This is the method recommended by NSA.
