I have a epson wf-2540 printer and it s fairly new I got it last december, and it has not been working. Every time I turn it on, and I have left it off and unplug for an extend period of time before trying again, it makes a loud shrill noise before saying it has a paper jam. I have checked up and down this machine and there is no paper in the machine. I have even tried changing the ink cartridges based on what I saw happened to other people and it makes the same noise and says it has a paper jam. Any ideas how to fix it?
