Due to the stuck black valve issue I recently replaced the ink supply and damper unit on my 3880. That all seemed to go well and printing looks great with one exception. Started print some 17x22 sheets and noticed that every print has a score mark about 1" from the right edge of the paper. Doesn't matter what paper settings or size I am using - the score is always there. Any suggestions? I am using the rear paper feed

Stuck starwheel or starwheel spring at that spot?

I'll have to check to see. I assume I need to disassemble again?

Well, I did respond based on the target image being a Z3100/3200 one but I have no idea how it is arranged on a 3880.

Late reply here. So I checked and you were correct. There is one starwheel that is stuck and not rotating like all the rest. It's one on the front loading tray so it's scoring after the ink is on the print and hence making the line. Is there a way to just disable that one?

Edit: I'm using the z3200 to profile my Epson 3880 thus the reason for the target
