The product's hard disk is used as a temporary storage area for print jobs. The Secure File Erase Mode utility
can erase information from the hard disk to prevent unauthorized access.
It provides three different levels of security:
●
Insecure Mode: In this mode, all file pointers to the data (table indexes) are erased. The contents of the
file remain on the hard disk until the disk space they occupy is needed for other purposes, the space is
then overwritten. This is the fastest mode of operation.
●
1-Pass Mode: In this mode, file pointers are erased and the disk space where the contents of the file
were stored is overwritten with a fixed character pattern. This mode of is slower than Non-Secure Fast
Erase, but all data is overwritten.
●
5-Pass Mode: In this mode, file pointers are erased and the disk space where the contents of the file
were stored is overwritten 5 times using an algorithm that prevents any residual data. This mode may
affect product performance.
Execute the Secure File Erase utility as follows:
1. In the Service Utilities submenu, scroll to Secure File Erase Mode and press this menu option.

Mode or 5-Pass Mode).
3. Wait for the diagnostic result and press OK.
NOTE: Erasing the files of the Hard Disk drive using either of the 1-Pass Mode or 5-Pass Mode is a very slow
process; 6 hours for the 1-Pass mode and 40 hours for the 5-Pass mode.
