Clicking sound and com error

So after a rebuild of the print system I went in this morning to hearing a clicking sound like a relay sound over and over and com error flashing
I turned it off and unplugged restarted and as it was starting up the clicking started again as it was initializing and shut down with the same error
The sound is coming from the left side of facing the front

 

Just got a chance to try it again
It’ a valuejet 1204
The exact code is E079
I put new print head dampers and maintenance station on
I had it printing near perfect
The only thing I had an issue with was the pinch rollers
I noticed tonight they were stuck pretty bad to the material but I’m not sure if that had anything to do with it. It was in auto clean standby mode

 

Thanks I’ll check it out
This stinks

 

So I guess I got lucky
I unplugged and plugged back in those Ethernet connections and it fired back up

 

Now time to replace the pinch rollers !

 

Hi guys
I have a strange issue. I noticed my platen heater is staying on even when in standby mode
Very hot
Anything I can do about that ?
