features. An Image Overwrite Security kit is available which enables both Immediate and On-Demand overwrite of
any temporary image data created on the NC disk. The Network Controller also incorporates an open-source web
server (Apache) that exports a Web User Interface (WebUI) through which users can submit jobs and check job
and machine status, and through which System Administrators can remotely administer the machine. The
Network Controller is sometimes referred to as the Electronic Subsystem (ESS).
The Network Controller (NC) runs Wind River Linux, kernel v. 2.6.20+. (Note: Consistent with Flaw Remediation, this
baseline may be updated as indicated by the ‘+’ sign. Unnecessary services such as rsh, telnet and finger are
disabled in the OS. FTP is used in client-only mode by the optional Network Scanning feature for the filing of
scanned images and the retrieval of Scan Templates; however the NC does not contain an FTP server.

Scanner
2.4.1.
Purpose
The purpose of the scanner is to provide mechanical transport of hardcopy originals and to convert hardcopy
originals to electronic data.
2.4.2.
Hardware
The scanner converts the image from hardcopy to electronic data. An optional document handler moves originals
into a position to be scanned. The scanner provides enough image processing for signal conditioning and
formatting. The scanner does not store scanned images. All other image processing functions are in the copy
controller.
The scanner has 1MB of non-volatile executable code and 128KB of scratchpad RAM.
