Additional Information:
The disk contains 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 de-allocated to be available for new images.
* All residual customer data in de-allocated space can be overwritten using a three pass algorithm which conforms to U.S. Department of Defense
Directive 5200.28.M. Xerox provides Immediate Image overwrite that overwrites user image data as soon as the job is complete plus the ability for the
SA to overwrite the entire spool partition, if desired.
Data stored on disk can be encrypted using Encryption option

External Connections
The controller printed wiring boards are physically mounted in a tray with external connections available at the
rear of the machine. In the single-board configuration the tray contains a power distribution board and a single
controller board. A optional fax board may also be installed. Disk(s) are mounted on the underside of the tray.
Below the controller tray are other connectors that distribute power and communications to external options such
as a finisher or high-capacity paper tray. There is also a port that provides debug access to the solid-ink marking
engine. This port is used to monitor functional status of the printhead. There is no internal path from this port to
the controller.
