XEROX WorkCentre 5735/5740/5745/5755/5765/5775/5790 Information Assurance Disclosure Paper

3.4.4.1.Access

The Xerox Service Technician must be authenticated twice:

1.The first password, called the PSW Lock Facility, is obtained by calling a Xerox service location and providing the CSE employee number and the serial number of the PSW. The password is then given to the Xerox Service Technician, and is valid for 90 days. When the password expires, the Xerox Service Technician must call in again. This password is unique to the client application running on that particular PSW, and is required to log onto the PSW prior to initiating communications with the machine.

2.Once the application is running, the PSW supplies the second password (different from the first) to authenticate the session to the device. This embedded password is automatically passed from the application to the machine, and is never seen by anyone. It is hardcoded in the software of the Marking Engine and the PSW application, and is common to all products. It is not encrypted. Many of the diagnostic routines will require this password in order to function.

3.4.4.2.Communication Protocol

The communication process uses a Xerox proprietary protocol. Each packet passing back and forth will have a unique identifier (session key) with it for authentication and tracking purposes. All protocols are API based – very little information is directly transferred. For example, in order to run any given diagnostic test, the ‘Start Test XXX’ command is sent to the Marking Engine. The Marking Engine runs the test and responds with a “Test XXX passed (or failed)’ reply. This is illustrated in the following diagram:

3.4.4.3.Network Diagnostics executed from the PSW

The PSW allows the technician to execute certain Network diagnostic tests by connecting directly to the serial port on the controller. These tests are executed with the device disconnected from the customer’s LAN.

The tests that are available are echo tests for the various protocols (e.g. IP, IPX), where the controller sends a dummy message to itself to test the transmit and receive capabilities of its own connectivity stacks. Each protocol is tested individually and each test must be invoked separately. The diagnostic sequence is as follows:

1)After the PSW and Marking Engine have established a connection, the PSW must send the expected synchronization message to the machine.

2)The Marking Engine will respond with an acknowledge message containing its serial number.

5790, 5755, 5775, 5735, 5740 specifications

The Xerox 5790, 5760, and 5765 are part of Xerox's well-known line of multifunction printers (MFPs), designed to meet the needs of businesses looking for efficient, high-volume printing, copying, and scanning solutions. These models provide a blend of advanced technology and user-friendly features, making them ideal for offices that demand speed and reliability.

The Xerox 5790 is a standout model in this series, offering exceptional printing speeds of up to 90 pages per minute. It features a robust paper handling system capable of accommodating various media sizes and types, including both standard and custom formats. This model integrates advanced imaging technology, providing high-quality output with sharp text and vibrant colors, thanks to its high resolution of up to 1200 x 1200 dpi.

The 5760 and 5765 models, while slightly lower in terms of speed – with the 5765 reaching up to 65 pages per minute – still maintain impressive performance levels suitable for medium to large-sized businesses. Both devices utilize Xerox's innovative EA toner technology, which delivers fine details and smooth gradients, making them particularly effective for graphics-intensive documents.

One of the key features across these models is their user-friendly touchscreen interface, which simplifies operation and allows for seamless workflow management. Users can easily access scanning, printing, and copying functions, with options to customize workflows according to specific job requirements. Additionally, these MFPs offer advanced scanning capabilities, such as double-sided scanning and scan-to-email features, enhancing productivity.

Connectivity is another highlight of the Xerox 5790, 5760, and 5765. They support a variety of networking options, including Ethernet and Wi-Fi, making it easy to integrate them into existing office networks. Furthermore, they are equipped with mobile printing options, allowing users to print directly from their smartphones and tablets, enhancing flexibility and convenience.

In addition to their powerful performance, these models also come equipped with various security features, such as secure print, user authentication, and data encryption, ensuring sensitive information remains protected. With their strong emphasis on sustainability, Xerox has designed these printers to be energy-efficient and equipped with features aimed at reducing paper waste, such as duplex printing.

In conclusion, the Xerox 5790, 5760, and 5765 multifunction printers combine speed, quality, and advanced technology, making them excellent choices for businesses looking to enhance productivity and workflow. Their range of features and capabilities ensures they can meet the demands of various office environments, all while maintaining a commitment to sustainability and security.
