I have a Sigma paper shreddder DS 155 at home which has started to 'pop' and blown the fuse. I have changed the fuse but it is not working, this is the second one I have purchased within 18 months. I followed insturctions on both machines, had to throw the first one away, what a waste! Can this machine be fixed and is it worth it.

paper detector stops half way through function , have to switch to reverse and back again to every sheet , any answers ?

Had the same problem , blown fuse and reverse motor function on. I found dry joints and broken track on the PCB where the photo transistor plugs in. Repaired the track and resoldered the pins and the unit started to work as normal in auto mode

Hi, I've got the same problem, but now that I fixed the fuse, the photo transistor (it is in a little black case withe 4 wires and a white number on it) of the paper detector is dead (you can try this: if on revers position the electric motor turns, you got the same problem...) But I don't know which type of photo transistor I have to use...
