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 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 SP 5169 to “1”.
3. After machine servicing is completed:
   • Change SP 5169 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.

SC CODE DESCRIPTIONS

Important

• If a problem concerns electrical circuit boards, always disconnect then reconnect the connectors before replacing the PCBs.
• If a motor lock error occurs, first check the mechanical load before replacing motors or sensors.
• When a Level “A” or “B” SC occurs while in an SP mode, the display does not display the SC number. If this occurs, check the SC number after leaving the SP mode.

How to Read These Tables

Most of the SC codes in these tables apply to both the B140 Series and B246 Series machines. However, there are some differences. These differences are annotated:

• If an SC code applies to the B140 Series machine only, this SC will be marked "B140" to the right of the number.
• If an SC code applies to the B246 Series machine only, this SC will be marked "B246".
• If there is neither a "B140" nor "B246" notation, the SC code applies to both machines.
• Pay special attention to the "B140/B246 Duplicated Number" notation. The same number SC codes exists in both machines but the meaning is different.
