DecalsLab 0 Posted September 28, 2018 Have Mh721, been good for more then 10 months now, but started to do weird stuff when carriage goes past the middle of the machine. What happens is - blade goes up and down randomly, still cuts the image as it should. Any suggestions how to treat this issue? Share this post Link to post Share on other sites
darcshadow 1,626 Posted September 28, 2018 My first thought would be the cable cable controlling the solenoid is damaged/wore out. Kinds out sounds like the wire is making and breaking it's connection as the head moves back and forth which causes the wire to bend and flex. Share this post Link to post Share on other sites
