Epson 5020UB flashing red lights
So my Epson 5020UB was working fine one day and then the next day I got the 2 red flashing lights. After researching it I found this article Epson 5010/6010 'Cinema filter Error', grinding noise, red light fix with pics
which describes the cinema filter error. I figured that was my problem as well. I pulled the top cover off and powered it on and the cinema filter wouldn't move at all. I followed the directions in the article above and took it apart. The motor and the gears were all fine. What happened to mine was the cinema filter somehow moved too far and moved past one of the micro switched and was jammed. I moved it back into place and now everything is working fine.
