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 Tools and then set "Service Mode Lock" to OFF after he or she logs in:
    "Machine Features" screen > "System Settings" > "Administrator Tools" > "Service Mode Lock" > OFF
    • You can access the "Machine Features" screen with the following procedure.
      • Pro C5200S/C5210S:
        • When using the standard operation panel: Press the "User Tools" key.
        • When using the smart operation panel: Press the "User Tools" icon, and then press "Machine Features".
      • MP C6503/C8003: Press the "User Tools" icon, and then press "Machine Features".
    • This unlocks the machine and lets you access all the SP codes.
    • The CE can service the machine and turn the machine power OFF then ON. 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 the machine power OFF then ON. Tell the administrator that you have completed servicing the machine.
    • The Administrator will then set the "Service Mode Lock" to ON.
