My Epson R800 printer is ON. As soon as I start a print and exactly at the moment where it should pull in the paper the printer goes OFF! No more action! Switching ON is no more possible. After removing power cord for several minutes I can again switch ON the printer. All looks fine the same thing happens again when the printer should do something. The communication looks good because on the PC I can check the level of the inks. Any idea about the problem? Thank you Armin
