At locations where the machine contains sensitive data, the service representative 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 as the machine administrator, and then set "Service Mode Lock" to OFF:
    IM 550F/600F/600SRF: Settings -> Machine Features Settings -> System Settings -> Administrator Tools -> Service Mode Lock -> OFF
    P 800/801: Security Options -> Service Mode Lock -> Off
    • This unlocks the machine and lets you get access to all the SP codes.
    • The service representative 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 SP5-169-001 to "1" if you must use the printer bit switches.
  3. After machine servicing is completed:
    • Change SP5-169-001 from "1" to "0".
    • Turn the main power off and on. Tell the administrator that you have completed servicing the machine.
    • The Administrator will then set the "Service Mode Lock" to ON.
