Question / Problem:

How to download Kofax Front Office Server (KFS) 4.x or 3.x MultiFunction Printer (MFP) Client Debug logs from a Lexmark MFP device to the KFS server

Answer / Solution:

When troubleshooting issues with the KFS MFP Client, it may be necessary to obtain the KFS MFP Client debug logs from the MFP device.

The following procedure will enable a Lexmark MFP to collect the KFS MFP Client debug logs and write them to the KFS.log on the KFS server:

  1. From any PC that can connect to the MFP, open the Command Prompt as administrator.
  2. Telnet into the MFP device using the following command, where <device ip> is the IP address of the MFP device:
    telnet <device ip> 4242

Note: The Microsoft Windows Telnet Client is not installed by default in Windows Vista, 7, 8, 8.1, Server 2008, Server 2008 R2, Server 2012, and Server 2012 R2. To install the Microsoft Windows Telnet Client, enter the following command:

pkgmgr /iu:"TelnetClient"

  1. Once the telnet connection has been established, enter the following command:
    sendlogs
  2. As the MFP collects the debug logs, it will write them to the req_queue folder on the MFP device. After the contents of the debug log files have been sent to the KFS server, the MFP will delete the files from this folder. The process is complete once all the files have been deleted from the req_queue folder.
    Periodically enter the following command to display the current list of files in the req_queue folder:
    dir req_queue
  3. When no more files remain in the req_queue folder, enter the following command to close the connection to the MFP and exit telnet:
    quit

  4. The content of the KFS MFP Client logs has been written to the following file on the KFS server:
    • KFS 3.x
      C:\Program Files (x86)\Kofax\Front Office
      Server\Avalin\jboss\server\avalin\log\KFS.log
    • KFS 4.x
      C:\ProgramData\Kofax\Front Office Server\Log\KFS.log
Note: If the volume of log data exceeds the file size limit of KFS.log, older entries will be archived to KFS.log.1, KFS.log.2, etc.
