Statement of Volatility
Your scanner contains various types of memory that are capable of storing device and network settings, information from embedded solutions, and user data. The following are the types of memory and the types of data they store:
Volatile memory—Your device utilizes standard Random Access Memory (RAM) to temporarily buffer user data during simple print and copy jobs.
Non-volatile memory—Your device may utilize two forms of non-volatile memory: EEPROM and NAND (flash memory). Both types are used to store the operating system, device settings, network information, scanner and bookmark settings, and embedded solutions.
Hard disk memory—Some devices have a hard disk drive installed. The scanner hard disk is designed for device-specific functionality and cannot be used for long term storage for data that is not print-related. The hard disk does not provide the capability for users to extract information, create folders, create disk or network file shares, or FTP information directly from a client device. The hard disk can retain buffered user data from complex scan, print, copy, and fax jobs, as well as form data, and font data.
There are several circumstances where you may want to erase the contents of memory of devices installed in the scanner. A partial list includes:
The scanner is being decommissioned.
The scanner hard drive is being replaced.
The scanner is being moved to a different department or location.
The scanner is being serviced by someone from outside your organization.
The scanner is being removed from your premises for service.
Disposing of a printer or scanner hard drive
| Note: Not all printers or scanners have a hard disk installed. |
In high-security environments, it may be necessary to take additional steps to ensure that confidential data stored on the scanner hard disk cannot be accessed once the scanner—or its hard disk—is removed from your premises.
Degaussing—Flushes the hard drive with a magnetic field that erases stored data
Crushing—Physically compresses the hard disk to break component parts and render them unreadable
Milling—Physically shreds the hard disk into small metal bits
| Note: The only way to guarantee that all data is completely erased is to physically destroy each memory device on which data could have been stored. |
Erasing scanner hard disk memory
Configuring Disk Wiping lets you remove residual confidential material left by scan, print, copy, and fax jobs, by securely overwriting files that have been marked for deletion.
Turn off the scanner.
Hold down
and 
while turning the scanner on. Release the buttons only when the screen with the progress bar appears.
The scanner performs a power-on sequence, and then the Configuration menu appears. When the scanner is fully powered up, the touch screen displays a list of functions, instead of the standard home screen icons.
Touch Wipe Disk, and then touch one of the following:
Wipe disk (fast)—This lets you overwrite the disk with all zeroes in a single pass.
Wipe disk (secure)—This lets you overwrite the disk with random bit patterns several times, followed by a verification pass. A secure overwrite is compliant with the DoD 5220.22-M standard for securely erasing data from a hard disk. Highly confidential information should be wiped using this method.
Touch Yes to proceed with disk wiping. A status bar will indicate the progress of the disk wiping task.
| Note: Disk wiping can take from several minutes to more than an hour, during which the scanner will be unavailable for other user tasks. |
Touch Back > Exit Config Menu.
The scanner will power-on reset, and then return to normal operating mode.
