Image Overwrite
You can set the machine to overwrite data stored in the memory. The machine
overwrites the data with different patterns eliminating the possibilities of
recovery.
This feature may not be available depending on models or option kits
installed.
• Automatic Image Overwrite: When a job is completed, there are temporal
images left in the memory. For security reasons, you can set the machine to
automatically overwrite secure non-volatile memory. If you want to secure
memory space, you can set the machine to automatically overwrite secure
non-volatile memory.
• Manual Image Overwrite: When printing, copying, scanning, and faxing,
the machine temporarily uses memory space. For security reasons, you can
set the machine to manually overwrite secure non-volatile memory. If you
want to secure memory space, you can manually overwrite secure non-
volatile memory. You can set the machine to repeat the manual image
overwrite after the system is rebooted.
• Scheduled Image Overwrite: you can set the schedule to manually
overwrite the image.
• Overwrite Method: You can select the method for overwriting the secure
non-volatile memory(hard).
