Additional Information:
This System disk contains the Linux Operating System and stores executables, fonts, and settings files. During normal
operation, job files do not remain stored on this disk. One exception is “Print From”, “Saved Jobs” feature. Customer jobs saved
on the machine’s hard disk using this feature must be manually deleted by the customer. If On Demand Overwrite and full is
selected all saved jobs will be erased.
The Image partition stores images in a proprietary encoded format in non-contiguous blocks. Customer image data is only
stored to the image partition if EPC memory is full. User data and image data may be completely erased with a full Overwrite
using a three-pass algorithm which conforms to U.S. Department of Defense Directive 5220.22-M, and the entire image
partition is erased and checked.
