My Epson AcuLaser C1100N suddenly not working today. The panel keeps saying "Jam MP E" which means paper jamming in MP (multipurpose tray) or E (back door), however, I've checked those doors numerous times and couldn't find any paper jamming.
Then, I noticed that the paper input tray does not picking up paper. Does anyone have any suggestion on this? (Before I call Epson on Monday. The machine is still under warranty.)
