The default username and password for the Fuji Xerox DocuCentre-IV C2260 is as follows:
Username: 11111
Password: x-admin
When accessing the web interface of the Fuji Xerox DocuCentre-IV C2260 if you attempt to change any settings you will be prompted for this username and password. The default that the copier is set to is in my experience not clearly identified in the manual.
When accessing the administrator menus on the copier the code 11111 is used.
