HP Laserjet M605N Printer Error

[erose5450]

We started getting an 81.09.00 embedded Jetdirect error on our printer.  We have had the printer in a network environment for over a year and it was working fine.   I called HP they did some initial troubleshooting which seemed to fix it that day but the next day we had the error again.   I called HP again they sent a tech with a new formatter board.  This seemed to fix the printer for about 1.5 weeks.  I called HP again and they sent a replacement printer - this printer displayed the same error.   I called hp again yesterday they sent a replacement printer today and this printer again is displaying the same error.   We connected the printer to a laptop peer to peer - no error and it printed fine - HP says this indicates the Jetdirect card is not bad.   We pull up a web page and navigate to the IP of the printer 169.x.x.xxx and I get a full page of options for the printer.   We print from the web page no issues.

I connect the printer back to our network and get the error instantly.   HP says its our network.   I have tried new cables, new power cable, a different RJ45 port...even a different location in the office and the error persists.   HP is putting the blame on our network.  Although nothing has changed in the network, no AV/Firewall, no windows firewall, and all other network printers are printing fine configured with either a static IP or handed down through DHCP.   Any help????

When I have network issues like yours I try to isolate the issue. The first thing I do is get a small switch and connect the printer and one computer to the switch and see if I can communicate with the printer without issue. If that works ok, I then connect the switch leaving the computer and printer connected to the network port previously used by the printer. I then see if I can print from other computers to this pirnter. If I can that will validate that the printer is fine and there is something funky with your network. I have also seen where it works fine with just the computer and printer to the switch and then when I connect it back to the network by connecting the switch to the network all of a sudden nothing works. That again would indicate a funky network. One thing you want to check is to make sure nothing else on the network has grabbed the ip address of the printer causing a conflict. To test write down the ip of the printer and then disconnect the printer and ping that ip address. If you get a reply that is your issue.
