Hi Sumontra,
We checked and it seems that all FAX queues have this error.
We tried several drivers and setting, also installed a new FAX queue manually and the problem still persist.
Could you please check if despite the error the FAX function is working?
Also could you please check and let us know if there are some configuration that should be
done via the Web page or physically on the device? Maybe somewhere the old server name is configured
and should be replaced by the new server.
Thank you for your feedback.
