Restore Factory Defaults; Entering Invalid Engine Mode - Lexmark MX310 Service Manual

Restore factory defaults

Restore Settings
This setting enables a user to restore all of the printer settings to either the network settings (on network models
only) or to the base printer settings.
To restore the settings:
1
From the Configuration menu, navigate to Restore Factory Defaults > Restore Settings.
2
Select from the available options:
•
Restore Printer Settings—restores all non‑critical base printer NVRAM settings.
•
Restore Network Settings—restores all network NVRAM settings.
•
Restore Apps—restores the factory default eSF configuration.
Erase Printer Memory
This makes any sensitive information that may exist on the volatile or non-volatile storage of the device
completely indecipherable. When selected, the printer performs a non‑critical NVRAM reset and then reboots.
Erase Hard Disk
This setting performs a wipe of the printer hard disk, erasing all data.
Warning—Potential Damage: This deletes all data on the printer hard disk, including downloaded fonts,
macros, and held jobs. Do not initiate a disk wipe if you have information on the printer that you want to
save.
Available options:
•
Single Pass Erase—overwrites all data and the file system. This wipe is faster but less secure since it is
possible to retrieve the deleted data with forensic data‑retrieval techniques.
•
Multi Pass Erase—overwrites all data without rewriting the file system. This wipe is DoD 5220.22-M compliant
since the deleted data is irretrievable.
Note: If the printer is reset while a disk wipe operation is executing, then Corrupt Disk appears upon
regaining power.
