    Hie guys, am running an LS40 2002 model. The machine is having what I suspect to be an electrical problem. When printing first side it is running but when backing up the machine won't take the paper, only one sheet goes in and the feeder stops. It doesn't show what the error is. I have tested my eyes(sensors) and all show that they are working. Please Help.

    Only thing I can think of is your double sheet detector might need resetting?

    I get this problem when doing work' n' tumble, jobs as the colour bar ends up on the gripper edge when backing up so the eye can not see through paper, solution.. Delete the part of the colour bar off the plate before printing the first side..hope this helps.
