adjust values.
ƒ
Never turn off the main power switch when the power LED is lit or flashing. To
avoid damaging the hard disk or memory, press the operation switch to switch the
power off, wait for the power LED to go off, and then switch the main power switch
off.
5.1.1 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:
ƒ [User Tools] > System Settings > Administrator Tools > Service Mode Lock > OFF
ƒ This unlocks the machine and lets you get access to all the SP codes.
ƒ The service technician can do servicing on 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. If you must use the printer bit switches, go into the SP mode and set SP5169 to “1”.
3. After machine servicing is completed:
ƒ Change SP5169 from “1” to “0”.
ƒ Turn the machine off and on.
ƒ Tell the administrator that you completed servicing the machine.
ƒ The administrator will then set the “Service Mode Lock” to ON.
