3. Refer to “Flow of Determining the Procedure for Obtaining Logs” on page 352 and when it is judged that collection
of the network packet logs is required, enable the network packet log collection function by following the procedure
shown below and start the function.
1. Enter a license in the following menu to enable network packet capture.
[Settings/Registration] > [Management Settings] > [License/Other] > [Register License]
2. Enable the setting (ON) in the following menu.
[Settings/Registration] > [Preferences] > [Network] > [Store Network Packet Log]
3. Set "1" in the following service mode (Lv.2).
Service mode > COPIER > TEST > NET-CAP > CAPOFFON
4. Refer to “Initial setting of Collecting Network Packet Logs” on page 356 , and configure the required option settings.
5. Set "0" or "1" in the following service mode (Lv.2) to start capture of network packets.
Service mode > COPIER > TEST > NET-CAP > STT-STP
• 0: Not automatically collect at startup (factory default setting)
• 1: Automatically collects at startup
6. Execute the following service mode (Lv.2) to check the status of the capture.
Service mode > COPIER > TEST > NET-CAP > CAPSTATE
The following types of status are displayed.
• RUNNING: Packets are being captured.
• STOP: Packet capturing is stopped.
• HDDFULL: The maximum amount of 1 GB of packets has been captured.

Setting the overwrite function
1. To enable this function, set "1" in the following service mode (Lv.2).
Service mode > COPIER > TEST > NET-CAP > OVERWRIT
NOTE:
When this setting is enabled, old logs will be overwritten. If the symptom cannot be reproduced, disable this setting (setting value:
0) and secure logs (save them using SST or USB).
After securing the logs, enable the setting (setting value: 1) again.
Behavior when HDD reaches the limit
When this setting is enabled (setting value: 1), the following behaviors will occur when the HDD reaches the limit.
• When overwrite setting is ON
• The oldest packet file is deleted. This "oldest file" is judged not by the date and time allocated to the file but
by the last update time of the file.
• If the HDD reaches the maximum size while retrieving packets, the oldest file will be deleted, and CAPSTATE
of the capture, which continues the retrieval process for the file which is being saved, remains "RUNNING".
• When overwrite setting is OFF
• The capture is stopped.
• The CAPSTATE of the capture will be "HDDFULL". However, STT-STP will remain as Start (1) status. By
changing STT-STP (0) to STTSTP (1), the capture resumes.
• When the capture resumes, the capture starts if HDDFULL has been solved.
• The CAPSTATE of the capture will be "RUNNING".
• If HDDFULL has not been solved, an error is generated as the result of resuming the capture.
• The CAPSTATE of the capture remains "HDDFULL".
• If the capture is stopped while the CAPSTATE is "HDDFULL", the CAPSTATE of the capture remains "STOP".
