Enabling the security reset jumper

The security reset jumper can reset a printer that is locked due to a forgotten password or lost network
connectivity.
Notes:
•
Resetting the printer deletes all security settings.
•
Before changing the security settings, ask for permission from your administrator.
1
Turn off the printer.
2
Access the controller board.
3
Move the jumper to cover the middle and exposed prongs.
Note: The small, yellow jumper is located beside a lock icon on the controller board.
4
Turn on the printer.
Notes:
•
Use a cable lock to secure the controller board and prevent a malicious reset.
•
For multifunction products, when the controller board is replaced, the security settings are lost and the
LDAP configuration and Copy function are no longer protected.
