Xerox Standard Accounting; Automatic Meter Reads; Encrypted Partitions - Xerox WorkCentre 6400 Information Manual

4.2. Xerox Standard Accounting

Xerox Standard Accounting (XSA), intended primarily for use as an accounting service, can be used as an internal
authorization service. XSA tracks copy, scan (including filing and email), print and fax usage by individual user1. The
system administrator can enable/disable the feature via the LUI or Web UI, add or delete users, and set usage limits by
service for each user. If XSA is enabled, a walk-up user must enter a valid XSA ID before being allowed access to the
device. The device will confirm that the entered XSA ID matches an authorized user, and that the usage limits for the
selected service have not been exceeded. In this sense, XSA acts as an authorization service. The system administrator
can limit access to device services by setting the usage limits on specific services to zero for users that should not have
rights to use the feature. After each job is performed, the user's balance is updated by the number of impressions or
scans performed. Services become unavailable to the user when the usage limits are exceeded.
When XSA is enabled in the print driver or on the Web UI, before a print job is submitted, an XSA ID must also be
entered. The ID is sent to the controller for validation. If the submitted ID is valid, the job will print, and the user's
balance will be updated by the number of impressions performed. If the submitted ID is invalid, the job is deleted and
an error sheet is printed in its place.
On demand, the SA will be able to download a report that shows activity for all of the users. The SA can add, modify or
remove users and their allocations at any point.
An end user will be able to review their balances by entering a User ID at the LUI or web UI.

4.3. Automatic Meter Reads

Automatic Meter Reads (AMR) is a service that allows devices to electronically report meter readings back to Xerox. The
Systems Administrator sets up the attributes for the AMR service via the web UI, including registering the device with
the Xerox AMR server. Once enabled, the device will poll the Xerox AMR server daily over the network. The server will
check whether it is time in the monthly billing cycle to update the meter readings. If so, the server will request reads
from the device, and the device will then respond by sending the meter reads back to the server.
This communication process means that the device initiates all communication between it and Xerox. Only device ID
and meter read information is transferred. The information is sent in clear text.
The device can be set to communicate via a proxy server on the customer's network. The proxy server address is set up
using the WebUI.

4.4. Encrypted Partitions

When enabled by the customer, the controller disks are encrypted using the AES algorithm with a 128-bit key. 256-bit
encryption is available via SPAR – please contact Xerox Customer Support and request SPAR 85669. The key is
generated dynamically on each boot, and is kept only in volatile memory. Encryption is installed but must be enabled
by the customer.
