I'm having an issue with the SC series with the blade slicing straight to the left and then grinding into the leftside of the machine until I cancel the job. For example, cutting 24 four inch stickers laid out over two rows. Half way thru the second row the blade takes off to the left slice as it goes and then just grinds into the left of the machine. Don't know where its trying to go, and don't know whats causing it. It seems random, sometimes it'll complete the job, sometimes it goes crazy. Could this be static as well?
