Additional Information:
These disks contain OS, stored executables, fonts, device settings and images, etc. Scan to Local File is supported on this device The
“Stored Job” files remain on the disk until deleted during normal operation. Other job files are deleted during normal operation.
The spooling space is dynamically allocated to each job; at the job completion this space is deallocated to be available for new images.
The images and files spooled to the hard drive and not being used can be erased during normal operation using Immediate Image
Overwrite, Scheduled Image Overwrite, and On Demand Image Overwrite.
All residual customer data in dellocated space can be overwritten using a three pass algorithm that conforms to U.S. Department of
Defense Directive 5200.28.M.
Data stored on disk can be encrypted using Encryption option.
