Appendix A Overwrite All Data Function (HDD Sanitization) At the 'End of Life' or 'End of Lease' where the MFP is to be discarded the Overwrite All Data function overwrites and erases all data stored in all spaces of the HDD. This function also resets all passwords back to factory default settings, preventing any leakage of data.

Overwrite All Data takes less than one hour in [Mode 1] at the minimum and approximately 9 hours in [Mode 8] at the maximum.
