Printemaster qm46. running two color. using a justfeed feeder. jamming after 3 or so go in. gettting 11-07, 15-08 codes. I have messed with pile hight, air blast. and tray arrival.
It would be helpful if you were able to take a video, upload it to youtube and give us the link. At least maybe take pictures of your setup. There are just too many factors involved to give you advice.
I believe both of those are "jam" codes. They are most likely not your problem....they're just telling you that you have a problem.
