If an On Demand Image Overwrite is successfully completed, the completion (finish) time shown on the printed On Demand
Overwrite Confirmation Report will be the time that the system shuts down.
•
If an On Demand Image Overwrite fails to complete because of an error or system crash, Xerox recommends that the
System Administrator immediately perform another On Demand Image Overwrite, but only after completion of a system
reboot.
3. Xerox recommends that the System Administrator change the SNMP v1/v2c public/private community strings from their default
string names to random string names.
4. Before upgrading software on a WorkCentre™ 4250/4260 Multifunction System machine please check for the latest certified
software versions. Otherwise, the machine may not remain in its certified configuration.
5. To maintain the certified configuration, it is recommended that acceptance of customer software upgrades via the network be
turned off/disabled on either the Local UI (Customer Software Upgrade screen) or the Web UI (Upgrade Management web
page). Disabling customer software upgrades also disables the ability of a WorkCentre™ 4150 Multifunction System machine to
accept a clone file.
6. System Administrator login is required when accessing the security features of a WorkCentre™ 4250/4260 machine via the Web
User Interface. Xerox recommends that the 'Remember my password' option not be checked so the password is not saved in
the client machine's Web Browser.
7. Caution: A WorkCentre™ 4250/4260 allows an authenticated System Administrator to disable functions like Image Overwrite
Security that are necessary for secure operation. System Administrators are advised to periodically review the configuration of
all installed machines in their environment to verify that the proper secure configuration is maintained.
8. The WorkCentre™ 4250/4260 provides the ability to enable one-off features through the device's Local UI, behind Tools access.
A user can reach the one-off features via the following path: Machine Status
The SFO (Special Feature Option) is intended for specific customer requests that do not represent baseline device behavior and
is not designed for general use. A customer request is developed as a software patch and assigned a specific SFO #. Once
implemented, the customer that requested the Feature is informed of the specific number and is enabled by the SA. These SFO's
cannot be changed by anyone other than the SA or a person designated by the SA who has Local UI access rights.
To ensure the WorkCentre™ 4250/4260 Multifunction System is operated according to the certified configuration, it is
recommended that SFO 7 be disabled and SFO 22 be enabled:
•
SFO 7 – Allows the System Administrator to enable and configure Telnet on the WorkCentre™ 4250/4260. Enablement of
SFO 7 will remove the WorkCentre™ 4250/4260 from the certified configuration. SFO 7 is disabled by default.
•
SFO 22 – Requires entry on the Local UI of the Admin Password in addition to the diagnostic PIN for anyone to perform a
Memory Clear of the WorkCentre™ 4250/4260 Multifunction System. SFO 22 is disabled by default. To enable SFO 22
press the following touch-pad keys from the Tools Pathway screen: User Interface
list, select Enable and press Save.
9. If a system interruption such as power loss occurs a job in process may not be fully written to the hard disk. In that case any
temporary data created will be overwritten during job recovery but a corresponding record for the job may not be recorded in
the completed job log or audit log.
10. The following windows are available from the Local UI to a WorkCentre™ 4250/4260. These windows provide standard system
configuration capability (with System Administrator login and authentication) or security related user functions:
•
Connectivity and Network Setup – Allows access to screens to set the various parameters associated with network
connectivity. It is accessible by selecting the 'Connectivity and Network Setup' button from the Tools Mode.
•
Delete Job Confirmation – Allows a user or System Administrator to confirm deletion of a job from an active (incomplete)
job queue. It is accessible by selecting the {Job Status} hard button on the machine, selecting the desired job from the
displayed Job Queue and then selecting the 'Delete' button from the displayed Job Status Job Monitor window.
•
Pausing an active job being processed by the device – Allows the user to pause an active scan or print job while it is being
processed by the WorkCentre™ 4250/4260. It is accessible by selecting the 'Stop' machine hard button while a job is being
processed by the device. Depending on the type of job being processed by the device, a Stop/Pause window should be
displayed to allow the user to determine whether to delete or continue processing of the job.
•
Job Details (Completed Jobs) - Allows a user to view the details of a selected completed job. It is accessible by (1) selecting
the {Job Status} hard button on the machine, (2) selecting the Completed Job tab on the displayed Job Queue window, (3)
selecting the desired Completed job queue from the three such "Completed" job queues available using the drop-down
menu, and then finally (4) selecting the desired job from the displayed "Completed" Job Queue window.
