Hello guys

I've recently started seeing vertical yellow lines through my prints. It only seems to be happening on the right hand side, see images below. In the first image I printed a dark yellow line and second image is of a planner with yellow streaks radomaly going through it. Anyone know whats causings this and a possible fix please.

Thanks , Mush

DIY Printer Fixing Guide
You are getting intermittent electrical shorts that are causing the heads to fire randomly. I would start by uninstalling the head cables, air dust the terminals, and then clean with 91% iso alcohol. Let dry and then reinstall the cables. Make sure you do this with the machine unplugged and wait 15 minutes before doing anything with the cables. If that doesn't fix the issue, it could be the long trailing cables that go from the slider board to the main board. It can also be a bad main board or just a plain old fried head.
