4.3 B140/B246 SERIES SERVICE MODE

4.3.1 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.
NOTE: This function is not used on B064 series machines.

  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

x This unlocks the machine and lets you get access to all the SP codes.
x 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.

  1. If you must use the printer bit switches, go into the SP mode and set SP 5169 to “1”.
  2. After machine servicing is completed: x Change SP 5169 from “1” to “0”. x Turn the machine off and on. Tell the administrator that you completed servicing the machine.

x The Administrator will then set the “Service Mode Lock” to ON.

4.3.2 B140/B246 SERIES SERVICE CALL CONDITIONS
There are 4 levels of service call conditions.
Level
Definition
Reset Procedure
A
Fusing unit SCs displayed on the operation panel. The machine is disabled. The user cannot reset the SC. Enter SP mode, then turn the main power switch off and on.
B
SCs that disable only the features that use the defective item. Although these SCs are not shown to the user under normal conditions, they are displayed on the operation panel only when the defective feature is selected. Turn the main power switch off and on.
C
SCs that are not shown on the operation panel. They are internally logged. Logging only
D
Turning the operation switch or main power switch off then on resets SCs Displayed on the operation panel. These are re-displayed if the error occurs again. Turn the operation switch or main power switch off and on.

4.3.3 B140/B246 SERIES SC CODE DESCRIPTIONS
Important
x If a problem concerns electrical circuit boards, always disconnect then reconnect
the connectors before replacing the PCBs. x If a motor lock error occurs, first check the mechanical load before replacing motors or sensors. x 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: x If an SC code applies to the B140 Series machine only, this SC will be marked "B140" to the right of the number. x If an SC code applies to the B246 Series machine only, this SC will be marked "B246".
x If there is neither a "B140" nor "B246" notation, the SC code applies to both
machines. x Pay special attention to the "B140/B246 Duplicated Number" notation. The same number SC codes exists in both machines but the meaning is different.

If the machine does not return one of the five HDD errors (SC860 ~ SC865), cycle the machine off and on. If this does not solve the problem, then initialize the NetFile partition on the HDD with SP5832 011 (HDD Formatting – Ridoc I/F).
NetFiles: Jobs printed from the document server using a PC and DeskTopBinder Before initializing the NetFile partition on the HDD please inform the client that:

  1. Received faxes on the delivery server will be lost
  2. All captured documents will be lost
  3. DeskTopBinder/Print Job Manager/Desk Top Editor job history will be cleared
  4. Documents stored on the document server, included scanned documents, will not be lost.
  5. The first time the network accesses the machine, the management information must be reconfigured (this will require a significant amount of time).

Before initializing the Netfile partition with SP5823 011, do the following:

  1. Enter the User Tools mode and execute “Delivery Settings” to print all received fax documents scheduled for delivery and delete them.
  2. In the User Tools mode, execute Document Management> Batch Delete Transfer Documents.
  3. Execute SP5832 011 then cycle the machine off and on. Recovery Procedure 3

If “Procedure 2” does not solve the problem, execute SP5832 001 (HDD Formatting – All), then cycle the machine off and on.
Executing SP5832 001 erases all document and address book data stored on the hard disks. Be sure to consult with the customer before executing this SP code.
Recovery Procedure 4
If “Recovery Procedures 1 to 3” fail to correct the problem, replace the HDD.

SC No.
Symptom
Possible Cause
The software performs an unexpected function and the program cannot continue. x Software defective, re-boot*1
991
C
Software error 3 B140
The software performs an unexpected function and the program cannot continue. However, unlike SC990, recovery processing allows the program to continue. x Software defective, re-boot*1

*1: In order to get more details about SC990 and SC991:
3) Execute SP7403 or print an SMC Report (SP5990) to read the history of the 10 most recent logged errors.
4) If you press the zero key on the operation panel with the SP selection menu displayed, you will see detailed information about the recently logged SC990 or SC991, including the software file name, line number, and so on. 1) is the recommended method, because another SC could write over the information for the previous SC.
