Ricoh MP C2503 Series User Manual

Each item of data is overwritten by a random number, then by its complement, then by another
random number, and is then verified.
• Random Numbers
Temporary data is overwritten multiple times with random numbers. The number of overwrites can
be selected from 1 to 9.
• The default method for overwriting is "Random Numbers", and the default number of overwrites is
3.
• NSA stands for "National Security Agency", U.S.A.
• DoD stands for "Department of Defense", U.S.A.
Using Auto Erase Memory
• When Auto Erase Memory is set to [On], temporary data that remained on the hard disk when
Auto Erase Memory was set to [Off] might not be overwritten.
• If the main power switch is turned off before Auto Erase Memory is completed, overwriting will stop
and data will be left on the hard disk.
• Do not stop the overwrite mid-process. Doing so will damage the hard disk.
• Should the main power switch be turned off before Auto Erase Memory is completed, overwriting
will continue once the main power switch is turned back on.
• If an error occurs before overwriting is completed, turn off the main power. Turn it on, and then
repeat from step 1.
