1.2.5 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 the machine off and on. It is not necessary to
ask the Administrator to log in again each time the machine is turned on.
2. Go into the SP mode and set SP5169 to "1" if you must use the printer bit switches.
3. After machine servicing is completed:
§ Change SP5169 from "1" to "0".
§ Turn the machine off and on. Tell the administrator that you have completed servicing the
machine.
§ The Administrator will then set the "Service Mode Lock" to ON.
