hi friends .
SM 74-4 prinect
Suddenly, this error is displayed at print time
but don't stop machine continues printing



I'll be thankful for any help about issue.

 

Hi,
This indicates that the ehernet connection between the IPCand the REK2 is no longer established, how often does the error occur? You can see the ethernet port on the IPC to check if data is being sent and received or you walk up to the main cabinet and check the ethernet port on the REK2

my machine is PRINECT VERSION
IPCand mean touch display ??
