I've discussed this in another thread before but it kinda died off, also I'm curious if people have had this problem with different machines...
I actually had to send my two Metaxas back to mike in order for him to take a look at them, no matter what I try, o rings, bands, different needle bend, different needle brands, different grommets, paper, tubes, after extended use I find ink climbs it's way up the needle way and coats the fly wheel, thus spitting all over my arm.
I've spent hundreds trying to remedy this problem to no avail...any thoughts?
