Securing data 45 Notes: • Encryption takes approximately two minutes. A status bar appears on the control panel indicating the progress of the disk encryption task. • After the disk has been encrypted, the printer returns to the Enable/Disable screen. Warning-Potential Damage: Do not turn off the printer during the encryption process. Doing so may result in loss of data. 4 Touch Exit Config Menu or Exit Config. The printer performs a power‑on reset, and then returns to normal operating mode. Checking disk encryption status 1 From the Embedded Web Server, click Select Reports > Select Device Settings. 2 In the Other Settings section, check the value for Disk Encryption. Note: You can also check the disk encryption status using MarkvisionTM Enterprise. Markvision provides an advanced search feature to view the disk encryption status on a fleet of devices. Erasing settings (non‑volatile memory) Most devices use two forms of non-volatile memory-EEPROM and NAND. These components store the device settings, network information, embedded solution applications, various scanner settings, and bookmark settings. No user-related print, copy, or scan data is stored in non‑volatile memory. The user may erase selected groups of data or all data. There is one "restore defaults" setting defined in the standard administrator menu to restore the basic operator settings. This setting is easily accessible but only restores basic settings. From the configuration menu or the device Embedded Web Server, you can add more options for erasing groups of settings (printer, settings, or application settings). The Erase Printer Memory option (also called Wipe All Settings on some devices) erases all contents stored on non‑volatile memory. Using Wipe All Settings completely clears all device settings, including network and security settings. Installed applications and their settings are also removed. Restoring default settings from the control panel 1 Navigate to the menu screen, and then touch Settings > General Settings > Factory Defaults. 2 Select Restore Now > Submit. Note: This feature does not remove the following settings: • Network settings or connections • Paper source settings • Country selections • Display language • Applications settings • CA certificate data • Security settings

settings, network information, embedded solution applications, various scanner settings, and bookmark

settings. No user-related print, copy, or scan data is stored in non
