Viewing and Changing User Data Settings Stored in the MFP/LP
• From SmartDeviceMonitor for Admin, it is possible to view and change the user data settings
stored in the MFP/LP. Only users authenticated as User Administrators are able to change these
settings. User data is stored in the HDD and is managed by the UCS.
• When the MFP/LP receives a request to view this data, the UCS loads the data out of HDD memory,
after which Netfile obtains the information via communication with the UCS and related modules.
Netfile then sends the data to SmartDeviceMonitor for Admin via the network. When the MFP/LP
receives a request to make changes to some of the data, Netfile obtains the new settings from
SmartDeviceMonitor for Admin, after which it communicates with the UCS and related modules.
The UCS then saves the new data to the HDD. In cases where data is received from
SmartDeviceMonitor for Admin for an address book data backup or restore, the data is encrypted
before it is sent. For more details on the UCS internal management of the address book data,
please see Data Protection.
• Even in cases in which SSL is not used, GWWS encrypts the user’s password using the DESS
module (but does not encrypt any other part of the user data). The DESS module also
communicates directly with the UCS to encrypt the Address Book data when performing an
Address Book backup.
Viewing and Changing Machine Configuration Data Stored in the MFP/LP
• In order to view or change the machine configuration settings obtained by Web
SmartDeviceMonitor for Admin, users must have an administrator-level User Account registered in
this utility. The machine configuration data is managed by multiple modules, including the FCS,
NCS, DCS and SCS. The main storage location of the data is the NV-RAM. When a request is
received to view configuration data, these modules directly assess the NV-RAM. Netfile then
communicates with these modules to load the data out of memory and send it on to Web
SmartDeviceMonitor for Admin.
• When making changes to the current MFP/LP settings, Netfile receives the new settings from Web
SmartDeviceMonitor for Admin and forwards them on to the appropriate module(s). The settings
are then saved to the NV-RAM.
