T830 Blue Screen with B Error Code only when connected to LAN Network

[DSjVn]

I am having an issue with a T830 DesignJet Plotter.  It goes to solid blue error state with power icon and B------ error code ONLY when I plug in the ethernet cable or connect wireless to our network.  This is the same issue as described in a previous post >>

Blue Screen Error Codes December 2020 - HP Support Community - 7890288

I performed a OOB reset and when I set up the plotter on a switch and my laptop not connected to the company network the plotter works fine.  It goes into this error state EVERY time it is connected to the network.  Obviously there is something on the network causing this, but does someone have some idea of what that might be?

Possible causes:

1. Corrupted print job or bad driver that keeps trying to send the job when printer is connected. Use wireshark to monitor traffic and find out what IP address is sending data just before the error occurs and diagnose from there.

2. Could be in compatible or bad network switch, try a different port or different switch.

Hi Repairatrooper, thank you for the assistance.  My next step was going to be to try to isolate the offending device or source of the error either to something on the wifi or ethernet switch.  I will probably end up with doing a wireshark trace.  I am not sure there is a print job in que on a computer causing this because after doing the OOB reset, the IP address is bound to be on DHCP and different than what it was initially.

When I am able to determine the cause of this, I will post back for future reference by others.  If you think of something in the meanwhile, feel free to post.
