Secure Disk Erase
You might need to protect deleted data from unauthorized access on the MFP hard drive.
Secure Disk Erase is a security feature that you can use to securely erase print and copy
jobs from the hard drive.
Secure Disk Erase offers the following levels of disk security:
Non-Secure Fast Erase. This is a simple file-table erase function. Access to the file is
removed, but actual data is retained on the disk until it is overwritten by subsequent data-
storage operations. This is the fastest mode. Non-Secure Fast Erase is the default erase
Secure Fast Erase. Access to the file is removed, and the data is overwritten with a
fixed identical character pattern. This is slower than Non-Secure Fast Erase, but all data
is overwritten. Secure Fast Erase meets the U.S. Department of Defense 5220-22.M
requirements for the clearing of disk media.
Secure Sanitizing Erase. This level is similar to the Secure Fast Erase mode. In
addition, data is repetitively overwritten by using an algorithm that prevents any residual
data persistence. This mode will impact performance. Secure Sanitizing Erase meets
the U.S. Department of Defense 5220-22.M requirements for the sanitization of disk
