I have a couple of Lemmark E250DN printers that when patched into specific subnets after a short period of time all the lights on the printer will start blinking as if there is a problem. What is strange is if I take the printer and patch it into a different subnet the printer is fine.
We are a Microsoft shop, a few Linux servers floating around, and a full Cisco switch/router shop. I have been able to reproduce this by bringing the printer back to my NOC and patching it into my core Cisco 5507 switch. I then change the VLAN assigned to the port the printer is patched into to switch back and forth between a subnet it works fine on and a subnet it does not. Looking at the configs in the switch(es) there is no difference between the subnets. Any thoughts? Thank you!
