How to download Kofax Front Office Server (KFS) MultiFunction Printer (MFP) SDK/J (Java) Client Debug logs from a Ricoh MFP device to the KFS server



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

To force a Ricoh MFP device to collect the Kofax Ricoh MFP Java Client debug logs and write them to the device-Ricoh-<device hostname>.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

The Microsoft Windows Telnet Client is not installed by default in Windows 8, 8.1, 10, Server 2012, Server 2012 R2, Server 2016, or Server 2019. 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:
  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:

  4. The content of the Kofax Ricoh MFP Java Client logs has been written to the following file on the KFS server:C:\ProgramData\Kofax\Front Office Server\Log\Webapp\device-Ricoh-<device hostname>.log

This procedure does not apply to the Ricoh KFS MFP Android Client
