I am the print administrator for a healthcare company. We run Windows Server 2008 R2 Standard SP1. We have 5 different model Xerox printers in our environment. One of them being the Xerox Phaser 3635MFP. Randomly, these printers go offline or into an error state andno one can print to them. We can't remote into them using their host names. We can only remote into them using their IP address.
This happens so randomly, that when it does happen now, I know what to look for. But I've not yet been able to figure out what is causing it. It appears these strange characters, most notably what appears to be a weird looking plus sign or cross finds it's way into the host name field on the printer which makes it error or go offline.
Does anyone know what could possibly be causing this?
