We have recently connected a Lexmark T630n printer to our TCP/IP network. When we set it up on a workstation, it works fine .... for a while. Then we will get a "Printer not ready" error message. We have discovered that if we go into the printers folder on the workstation and view the port properties of the printer; it will start working again. We don't change anything -- just viewing it will somehow make it want to work again. The problem is the same in Win XP and Win 98 SE.
We have other network printers that don't have this problem. The only peculiar thing that I have noticed is that the T630n gives a message on its LED stating "WARNING: Gateway specified is not reachable". The gateway that we use is the same one used on our workstations. It is the address for our Cisco router to reach the internet. It is not in the same range as our workstations. Our workstations and the printer all have static IPs.
Any ideas would be appreciated. It's a real pain to have to stop and view the properties three or four times daily. Thanks.
