the memory. The machine overwrites the data with
different patterns eliminating the possibilities of
recovery.
• 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
