Error with Epson AcuCX11NF printer

I just installed a new Epson multi-function color laser jet on my computer network. It prints correctly, but after every print job, it gives this error that I need to click through: "AL-CX11-CCF782 TCPIP, Unknown error, Check the printer." Has anyone else had this error, and if so, how did you stop it from reappearing everytime you printed something? The printer still works, so it's more annoying than anything else.
