Bottom Two Lights Flashing


Was printing recently and paper tray ran empty. Then cartridges jammed to the right side and bottom two lights flashed continuously, in spite of disconnecting power, restart, etc. Finally, in attempt to change ink cartridges, pushed down on housing for ink cartridges and heard a click. They were jammed in the far right position. Restarted printer and all worked fine. Not very techy, but it worked!
