Graphical User Interface (Gui); Marking Engine (Also Known As The Image Output Terminal Or Iot); System Software Structure - Xerox WORKCENTRE 7755 Information Manual

XEROX WorkCentre 7755/7765/7775 Information Assurance Disclosure Paper
2.4.3. Control and Data Interfaces
Scanned images are transmitted from the scanner to the copy controller across a proprietary interface.

2.5. Graphical User Interface (GUI)

2.5.1. Purpose
The GUI detects soft and hard button actuations, and provides text and graphical prompts to the user. The GUI is
sometimes referred to as the Local UI (LUI) to distinguish it from the WebUI, which is exported by the web service
that runs in the Network Controller. Images are not transmitted to or stored in the GUI. The Start hard button is
located on the GUI panel.
2.5.2. Control and Data Interfaces
The GUI communicates with the copy controller across a proprietary interface.
2.6. Marking Engine (also known as the Image
Output Terminal or IOT)
2.6.1. Purpose
The Marking Engine performs copy/print paper feeding and transport, image marking and fusing, and document
finishing. Images are not stored at any point in these subsystems.
2.6.2. Hardware
The marking engine is comprised of paper supply trays and feeders, paper transport, laser scanner, xerographics, and
paper output and finishing.
2.6.3. Control and Data Interfaces
Images and control signals are transmitted from the copy controller to the marking engine across a proprietary
interface.

2.7. System Software Structure

2.7.1. Open-source components
Open-source components in the connectivity layer implement high-level protocol services. The security-relevant
connectivity layer components are:
•
Apache 2.2.4, with mod_ssl integrated (http and https)
•
OpenSSL 0.9.7h (SSL)
•
SAMBA 3.3.30 (SMB)
•
Netsnmp 5.0.9 (SNMPv3)
2.7.2. OS Layer in the Network Controller
The OS layer includes the operating system, network and physical I/O drivers. The baseline for the product launch
version of the Network Controller
from kernel.org and modified by Xerox.
consistent with Flaw Remediation, in which case the Xerox portion of the version number will be incremented.
The crypto library for IPSec is provided by the kernel.
