Disk Encryption
Controls whether the printer encrypts the information that it writes to the hard disk.
Warning:
When the value for Disk Encryption, the printer completely formats the hard disk which means that all
information on the disk is deleted.
Note:
If an encrypted disk is removed from the printer and another disk is installed, the
Disk Corrupted.
Reformat?
message appears. The newly installed disk must either be formatted or removed from the printer.
Selections include
Disable
(default) and
Enable
. When Disk Encryption is selected, Yes or No appears for you
to confirm. Select either
Yes
or
No
to continue. To cancel, select
No
.
The Disk Encryption menu item only appears when:
• A non-defective disk is installed in the printer.
• The values of bits 3-2 of digit 4 in the Configuration ID 2 are either 01 for Supported, or 10 for Supported
with an internal network adapter (INA).
A graphic appears, showing:
•
The message
Encrypting Disk
or
Formatting Disk
•
A percentage scale
•
The message
DO NOT POWER OFF
The process is complete when the percentage scale displays 100.
Wipe Disk
Note:
Due to the lengthy amount of time required to wipe an entire hard disk using either method, a wipe should
not be initiated unless it is absolutely unavoidable (for example, disk corruption), or unless the printer can
remain offline for several hours without inconveniencing users.
Warning:
A user should not initiate either type of wipe from the Configuration Menu if the hard disk contains
downloaded fonts, macros, held jobs, and so forth that should not be erased.
This setting initiates either a single pass wipe or a multiple pass wipe of the entire hard disk. Select
Disk Wipe
(fast)
to complete a single pass wipe and replacement of the file system. Select
Disk Wipe (secure)
to
complete a multiple pass wipe at a more basic level.
Wipe All Settings
The purpose of this setting is to make any sensitive information that may exist on the device’s volatile or non-
volatile storage completely indecipherable.
After selecting this setting, the operator panel displays the following message:
This operation will clear all settings, solutions, and jobs on this device. The device will
reboot during this process. Continue?
To cancel the NAND wipe operation and return to the main Configuration Menu, select
No
. To execute the
NAND wipe operation, select
Yes
.
After selecting
Yes
, the device initiates a non-critical NVRAM reset, and the operator panel displays the
message Resetting the device , and then the device reboots.
The progress bar area of the Lexmark logo screen that appears during boot up displays the following message
until the wiping process is finished:
Wiping disk...Pass [x] of [y]. [Z]% done.
