The paper appears to be curling upwards and hitting the print head. When your environment is very dry (low humidity), paper has a tendency to contract. You can either carefully bend the paper backwards by rolling it from diagonal to diagonal (careful not to damage it or dog ear it) - or you can increase the humidity. You should not be printing with an Epson below 35% rH. In any event - quite a striking image! Sorry that the print head struck it... Let us know if these suggestions remedy.
