Hard Disk Overwrite
You can select either of the following two methods to overwrite data:
Once Overwrite
Overwrites the entire area used to store old document data with zeroes to reject recovery of the data. The entire hard disk is overwritten with zeroes during a format operation.
Overwrites the entire area used to store old document data twice with a random pattern and then a third and final time with zeroes. It takes longer to execute than the Once Overwrite, but because even highly- sophisticated recovery methods are unable to recover the data, this method provides higher security. The area to be overwritten is the same as for the Once Overwrite.

Old data has been overwritten.
Important! To avoid damaging the hard disk, do not turn the copier power off during overwrite (while the hard disk icon is alternating between the two icons).
