Service Mode Lock/Unlock
At locations where the machine contains sensitive data, the customer engineer cannot operate the machine until the
Administrator turns the service mode lock off. This function makes sure that work on the machine is always done with the
permission of the Administrator.
1. If you cannot go into the SP mode, ask the Administrator to log in with the User Tool and then set "Service Mode
Lock" to OFF after he or she logs in:
User Tools > System Settings > Administrator Tools > Service Mode Lock > OFF
 This unlocks the machine and lets you get access to all the SP codes.

The CE can service the machine and turn OFF then ON the machine power. It is not necessary to ask the
Administrator to log in again each time the main power is turned ON.
2. Go into the SP mode and set SP5-169 to "1" if you must use the printer bit switches.
3. After machine servicing is completed:
 Change SP5-169 from "1" to "0".

Turn OFF then ON the machine power. Tell the administrator that you have completed servicing the machine.

The Administrator will then set the "Service Mode Lock" to ON.
