•  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 or software reset initiated from the Local User Interface or the Web User Interface.  
•  The System Administrator should perform an On Demand Image Overwrite immediately before a WorkCentre™ 5135/5150 
Multifunction System is decommissioned, returned, sold or disposed of. 
6.  The WorkCentre™ 5135/5150 Multifunction System supports the use of SSLv2.0, SSLv3.0, RC4 and MD5. However, customers are 
advised to set the cyrpto policy of their clients to request either SSLv3.1 or TLSv1.0 and to disallow the use of RC4 and MD5.

•  Any self-signed digital certificate or digital certificate signed by a Trusted Certificate Authority should have a maximum 
validity of 180 days.  
•  If a self-signed certificate is to be used the generic Xerox root CA certificate should be downloaded from the device and 
installed in the certificate store of the user's browser.

will disable the Web UI. Note: IP Filtering is available only with IPv4, and is not available for either the AppleTalk protocol or the 
Novell protocol with the ‘IPX’ filing transport.
