I have an issue where the vinyl runs forward to check material, but doesn't stop and just keeps on going out the back. Rollers keep moving until I turn it off. Not sure if it is a sensor problem. It happen directly after installing new ink cartridge, which after inserting and closing cover the roll wouldn't advance and it kept printing over in the same spot. Had to remove all the pinch pads and clean them, now it just check for material and runs out the back of the machine. Has this happened to anyone else?
