1. CAPTURING THE DEVICE LOGS

   
   

   1. OVERVIEW

      With this feature, you can save device logs that are stored in the machine (HDD or operation panel) or an SD card. It allows the Customer Engineer to save and retrieve error information for analysis.

      The Capturing Log feature saves device logs for the following four.

      • Controller device log including operation log

      • Engine device log

      • FCU device log

      • Operation panel log

        
        

        • In older models, a technician enabled the logging tool after a problem occurred. After that, when the problem had been reproduced, the technician was able to retrieve the device log.

        • However, this new feature saves the device logs at the time that problems occur. Then you can copy the logs to an SD card.

        • You can retrieve the device logs using a SD card without a network.

        • Analysis of the device log is effective for problems caused by the software. Analysis of the device log is not valid for the selection of defective parts or problems caused by hardware.

        • Make sure to shut down and reboot the machine once before retrieving the Debug Logs. Otherwise, the latest settings may not be collected when the debug logs are retrieved.

          Types of device logs that can be saved

          
          

          Type	Storage Timing	Destination (maximum storage capacity)
          Controller device log including operation log		HDD (4 GB) or SD card connected to the service slot. When the data gets over 4.0 GB, the older data is deleted.

          • Saved at all times

          Type	Storage Timing	Destination (maximum storage capacity)
          Engine device log		HDD or SD card connected to the service slot (Up to 300 times)
          FCU device log		HDD or SD card connected to the service slot
          Operation panel log		Memory in the operation panel.

          • When an engine SC occurs

          • When paper feeding/output stop because of a jam

          • When the machine doors are opened during normal operation

          • When a specified amount of FCU device log is stored in the FCU. If fax application is unavailable (e.g. not installed), the machine does not transfer the log.

          • When an error related to the operation panel occurs.

          
          

          System Maintenance

        • Device logs are not saved in the following conditions:

        • While erasing all memory

        • While data encryption equipment is installed

        • While changing the firmware configuration

        • Forced power OFF (accidentally disconnecting the outlet)

        • Engine device log while the machine is shutting down

        • When the power supply to the HDD is off because of energy saving (engine OFF mode/STR mode)

        • When one of the following SCs occurs: SC672, SC816, SC819, SC878, SC899, SC859, SC860, SC861, SC863, or SC864

        • The following logs are not saved:

        • Logs related to the energy saver mode (Engine-off, suspend-mode, or other cases) Network communication log

          Logs related to NRS IP-FAX log

          Access log for unauthorized users (guests)

        • HTTP session timeout log

        • Auto log-out log

        • IC card related log

        • Authorization for Fax

          
          

        • The default save destination is the HDD. Except when it cannot be saved to the HDD for some reason, there is no need to change from the HDD to an SD card.

        • If you want to change the save destination to an SD card, do the following.

          1. Set SP5-858-002 (Collect Machine Info: Save To) to ”1 (SD)”

          2. Execute SP5-858-003 (Collect Machine Info: Make Log Trace Dir) to make a folder for the log in the SD card.

          3. Turn the power switch OFF and ON.

        • It is recommended to use the SD card (8 GB) provided as a service part. The part number of the SD card that is registered as a service part is "B6455040".

          
          

          Security of the Operation Log

          The following operation logs related to security are not saved.

      • User ID

      • Password

      • IP address

      • Telephone number

      • Encryption key

      • Transition to SP mode

        
        

   2. RETRIEVING THE DEVICE LOGS VIA OPERATION PANEL

      
      

      • Retrieve device logs to identify the date of occurrence of the problems and to find details of the problems

      • e.g.: At around 8:00 am on March 10, an engine stall occurred. The operation panel does not respond. Turn the main power supply off / on.

      • Analysis of the device log is effective for problems caused by the software. Analysis of the device log is not valid for the selection of defective parts or problems caused by hardware.

      System Maintenance

      Procedure for Retrieving the Device Log with SD Card

      1. Insert the SD card into the slot on the side of the operation panel or the service slot.

         
         

         • It is recommended to use the SD card (2 GBs* or 8 GBs**) provided as a service part. This is because the log data can be acquired much faster than when using commercially available SD cards.

         • Format the SD card by using SD Formatter from Panasonic before copying the logs: https://www.sdcard.org/downloads/formatter_3/ (free software)

         • Insert the SD card into the machine's service slot instead of the SD slot on the side of the operation panel.

           * The part number of the SD card with 2 GBs that is registered as a service part is "B6455030".

           ** The part number of the SD card with 8 GBs that is registered as a service part is "B6455040".

      2. Turn ON the main power.

      3. Enter SP mode.

      4. Specify the date that the problem occurred in SP5-858-101 (Start Date) by setting it to the year-month-day calendar format.

         • For example, if a problem occurred on February 1, 2015, the date should be set to "20150201", as shown above.

         • Be sure to confirm the date when the problem occurred before obtaining the logs.

      5. Specify the number of days to collect the logs in SP5-858-102 (Days of Tracing).

         • "2" is set by default, which is the minimum needed for investigating the problem.

         • A value of "1" to "180" can be set.

      6. Execute SP5-858-111 (Acquire All Info & Logs) to copy all of the log types to an SD card.

         It is possible to obtain the logs separately by the following SPs.

         
         

         SP	Collectable Information and/or Logs
         SP5-858-111	All of the information and logs that are collected by executing the SPs from SP5-858-121 to SP5-858-145, and SMC.
         SP5-858-121	Configuration page
         SP5-858-122	Font page
         SP5-858-123	Print settings list
         SP5-858-124	Print Error log

         SP	Collectable Information and/or Logs
         SP5-858-131	Fax information (whether the fax destinations are included or not depends on the setting of SP5-858-103.)
         SP5-858-141	Controller log, engine log, operation panel log, FCU, and SMC.
         SP5-858-142	Controller log
         SP5-858-143	Engine log
         SP5-858-144	Operation panel log
         SP5-858-145	FCU log
         SP5-992-001	SMC

         
         

      7. After executing the SP for copying the information and/or logs, a confirmation screen will appear. To proceed with obtaining the information and/or logs, tap "Execute"

         

         
         

         • The approximate time it takes to transfer the debug log is as follows. Transfer time may be affected by the type or format of the SD card.

           Controller device log (GW device log): 2 - 20 minutes Engine device log: 2 minutes

           Operation panel device log: 2 - 20 minutes

           If the estimated time is not calculated due to an error, an error code will be displayed.

           
           

           Error Code	Description
           -1	Other.

           Error Code	Description
           -2	No SD card is inserted in the service slot or in the SD slot on the side of the operation panel. In this case, insert an SD card into either of the SD slots.
           -3	The SD card is locked. In this case, unlock the SD card, as shown below. [A]: Unlocked, [B]: Locked

           
           

           System Maintenance

      8. Wait for the information and/or logs to be copied to the SD card.

         
         

         

      9. After a message stating that the process has completed appears on the operation panel, confirm that the LED light next to the SD card slot is not flashing and then remove the SD card.

      10. Make sure that the SD card access LED is off, then remove the SD card.

          
          

          • The process of obtaining logs fails in the following cases:

            • When the size of the logs to obtain exceeds the amount of space available on the SD card.

            • When the SD card is removed while the logs are being copied to it.

            • When the SD card is not formatted.

          • If ‘failed’ appears on the touch panel display, turn the power off, and then recover from step 1 again.

   3. RETRIEVING THE DEVICE LOGS VIA WEB IMAGE MONITOR

The device logs can be retrieved via the Web Image Monitor.

1. Access the following URL and logon as an administrator:

   http://[IP address or host name]/web/entry/df/websys/direct/getSysInfo.cgi

   
   

   

2. Specify the date that the problem occurred and the number of days to download the logs. If the fax destinations need to be included in the fax information, set "On" as "Obtain Fax Destination(s) Information". Then click "Download".

   
   

   

   
   

   • "3" is set by default for "Number of days, including date fault occurred, to obtain". However "2", which is the minimum needed for investigating the problems, is recommended for reducing the downloading time.

   • "Obtain Fax Destination(s) Information" is set to "Off" by default.

3. The confirmation screen will appear and the information and/or logs will start downloading. To proceed to download the information and/or logs, wait for the open-or-save dialog to appear.

    • The file format for exports is CSV.

  1. CARD SAVE FUNCTION

     
     

     1. OVERVIEW

        
        

        Card Save:

• The Card Save function is used to save print jobs received by the printer on an SD card with no print output. Card Save mode is toggled using printer Bit Switch #1 bit number 4. Card Save will remain enabled until the SD card becomes full, or until all file names have been used.

• Captures are stored on the SD card in the folder /prt/cardsave. File names are assigned sequentially from PRT00000.prn to PRT99999.prn. An additional file PRT.CTL will be created. This file contains a list of all files created on the card by the card save function.

• Previously stored files on the SD card can be overwritten or left intact. Card Save SD has "Add" and "New" menu items.

  • Card Save (Add): Appends files to the SD Card. Does not overwrite existing files. If the card becomes full or if all file names are used, an error will be displayed on the operation panel. Subsequent jobs will not be stored.

  • Card Save (New): Overwrites files in the card's /prt/cardsave directory.

    Limitation:

• Card Save cannot be used with PJL Status Readback commands. PJL Status Readbacks will not work. In addition they will cause the Card Save to fail.

  1. PROCEDURE

     1. Turn OFF the main power.

     2. Insert the SD card into slot 2 (lower), then turn ON the main power.

     3. Enter SP mode.

     4. Select the "Printer SP".

     5. Select SP-1001 "Bit Switch".

        
        

        

     6. Select "Bit Switch 1 Settings" and use the numeric keypad to turn bit 4 ON and then press the "#" to register the change. The result should look like: 00010000. By doing this, Card Save option will appear in the "List/Test Print" menu.

  1. TROUBLESHOOTING

     
     

     1. SELF-DIAGNOSTIC MODE

        
        

        1. SC AUTOMATIC REBOOT

           When an ordinary SC (pattern D) is generated, automatically reboot is performed. Automatic reboot or reboot by user operation can be set by SP5-875-001 (SC automatic reboot setting out) (default value: 0 "Automatic reboot").

           When a type D occurs, automatic reboot is done or the machine display asks the customer if it can reboot. However, when the SC occurs twice in a short time, the machine sends a report to the

           @Remote server without rebooting. This is because just rebooting may not be a good solution if an SC occurs twice.

           When an automatic reboot is performed, a confirmation screen is displayed after reboot. The confirmation screen can be cancelled by pressing the [OK] key (display is not cancelled only when the main power switch is switched OFF to ON).

           Screen display during reboot

           • Status display on the current screen

             • Post-processing ...... Post-processing during printing, etc.

             • Automatic reboot .... After operation end Post-processing

               

               Until automatic reboot

               

           • Reset key (Reboot key) Key to perform reboot

             # Cancel key is not displayed.

           • Turn on spanner LED (same as when an SC is generated).

             Operation during SC reboot

           • Timing of SC reboot

             When @Remote is enabled, and when a NRS alarm*1 is not generated, the corresponding SC is the object of an automatic reboot.

             *1 NRS alarm: Issued when an ordinary SC (type D) is generated twice while the total counter counts 10 times.

           • Time to automatic reboot

             Reboot is performed 30 seconds after an engine reboot is possible, after the end of post-processing during printing, etc.

             At that time, a reboot is performed even if the MFP is operating. The engine does not start process control when a reboot is possible.

           • Automatic reboot

             See the flowchart below.

             Troubleshooting

        2. CONTROLLER SELF-DIAGNOSIS OUTLINE

           Controller self-diagnosis includes 3 types, i.e., "ordinary self-diagnosis", "detailed self-diagnosis", and "SC detection". "Ordinary self-diagnosis" is diagnosis performed for every power ON, and "detailed self-diagnosis" is diagnosis treated as part of the service tools. "SC detection" detects mechanical faults when power is switched on or when the machine is operating.

           Detailed self-diagnosis – Method

           1. After attaching the option "IEEE 1284 board" to the controller board, connect the provided conversion connector.

           2. Set a loop back connector in the reference Centronics I/F.

           3. Press the main power supply switch while simultaneously pressing the "#" and "./* key. The display changes to the following screen, and self-diagnosis starts.

              

           4. After the end of detailed self-diagnosis, a "Self-diagnosis results report" is automatically printed.

              • If a Centronics loopback connector is not fitted, a Centronics diagnosis error (SC 835) is generated.

        4. HDD-RELATED MESSAGE

           When an error occurs to the HDD, the HDD abnormality message appears on the operation panel and the screen for formatting is displayed. Also when replacing the HDD, a message "Hard Disk is replaced." appears on the operation panel and the screen for formatting is displayed.

           Refer to the table shown below for the conditions of the message display.

           
           

           Even when replacing the controller board, a banner "Hard Disk is replaced." appears. It is because the machine recognizes HDD has been replaced when the controller board that does not hold the HDD identification information is attached.

           Message list

           
           

           Message	Display Type	Normal/ Abnormal	Error Condition/ Major Cause/ Solution

     2. SERVICE CALL CONDITIONS

        
        

        1. SUMMARY

           The ‘SC Table’ section shows the SC codes for controller errors and other errors. The latter are put into four types. The type is determined by their reset procedures. The table shows the classification of the SC codes.

           
           

           Type	Display	How to reset
           A	The SC is immediately displayed on the operation panel when SC occurs. The error involves the fusing unit. The machine operation is disabled. The user cannot reset the error.	Reset the SC (set SP5-810-1) and then cycle the main power off and on.
           B	When a function is selected, the SC is displayed on the operation panel. The machine cannot be used (down-time mitigation).	Turn the operation switch off and on.
           C	No display on the operation panel. The machine operates as usual.	Only the SC history is updated.
           D	The SC is displayed on the operation panel. The machine cannot be used (machine-error SC).	Turn the main n power switch off and on.

           • When canceling a fusing unit SC, (SC544-00/ SC554-00/ SC564-00/ SC574-00), perform part replacement in accordance with the above procedure.

           
           

           • When an ordinary SC (type D) is generated, an automatic reboot is performed. When an event is reported by the customer support system, even in the event of an ordinary SC, reboot is not performed. During automatic reboot, a confirmation screen is displayed after the reboot.

           • When automatic reboot occurs twice continuously, an SC is displayed without rebooting, and logging count is performed. Also, when an SMC print is output, an * mark is added alongside the SC number for clarity.

           • Automatic reboot can be enabled or disabled with SP5-875-001 (SC automatic reboot setting) (default value: ON).

             SP descriptions

• SP5-875-001 (SC automatic reboot: Reboot Setting)

Enables or disables the automatic reboot function when an SC error occurs.

0: The machine reboots automatically when the machine issues an SC error and logs the SC error code. If the same SC occurs again, the machine does not reboot.

1: The machine does not reboot when an SC error occurs. The reboot is not executed for the pattern A or C.

SC Logging

When an SC is generated, the "total count value when the SC is generated" and the "SC code" are logged. However, if the total count value during the SC is the same as last time, logging is not performed.

Logged data can be checked by outputting an administrative report (SMC print). The SC history is logged up to the last 10 entries, and if there are more than 10 entries, data are progressively deleted starting from the oldest.
