Image Overwrite

User information created during the copying, printing, network scanning, scanning to e-mail, or scanning to server
processes is immediately recorded on the MFP's hard drive. To secure this information, the MFP software implements an
image overwrite function to erase image data created during the copying, printing, network scanning, scanning to e-mail,
or scanning to server processes. The MFP software performs three overwrite passes of the data using the methods defined
in Department of Defense (DoD) 5220.22-M (ECE). The MFPs can perform the following image overwrites:
•

Automatic Image Overwrite

•

Manual Image Overwrite

8.2.1 Automatic Image Overwrite
The Automatic Image Overwrite feature overwrites temporary image files automatically after the completion of each MFP
task.
8.2.2 Manual Image Overwrite
The Manual Image Overwrite feature allows the MFP System Administrator to manually perform a data overwrite of the
HDD data.
8.2.3

Scheduled Image Overwrite

The Scheduled Image Overwrite feature allows the MFP System Administrator to reserve a data overwrite of the HDD data
base on assigned schedule (Frequency, Day, Week, and Time).
8.2.4

Image Overwrite from the Local UI.

The system automatically overwrites temporary files created during processing and manually overwrites temporary files
created during processing on a specially-reserved section of the hard drive (Automatic Image Overwrite).
The image overwrite security function can also be invoked manually by the system administrator. Once invoked, it cancels
all print and scan jobs, halts the printer interface (network), overwrites the contents of the reserved section on the hard
drive, and then it reboots the main controller. When a power failure interrupts the manual overwrite, the process will
restart automatically after the power returns allowing it to finish overwriting all of the remaining files (Manual Image
Overwrite).
