5.1.1 SERVICE PROGRAM MODE OPERATION
The service program (SP) mode is used to check electrical data, change modes,
and adjust values.
CAUTION
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.
Service Mode Lock/Unlock
At locations where the machine contains sensitive data, the service 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 service engineer 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:
•
Change SP5169 from “1” to “0”.
•
Turn the machine OFF and ON.
•
Tell the administrator that you completed servicing the machine.
•
The administrator will then set the “Service Mode Lock” to ON.
