Maybe Capping Station Alignment I was having black ink being drawn up into my yellow as well. My tech brought in a Mimaki supplied jig that lined up the capping station properly and the problem went away. He said it was from air entering the capping station because of misalignment. He also...

What is the proper procedure for installing a JV5 damper. Can you damage a head by drawing ink through a disconnected damper?

Yes, Set to rear heads Yes we set it to the rear heads. We don't use the dual mode on the JV4, always seemed to be a alignment nightmare. But we do use 2 inksets, one for poly, one for nylon inks(we print on paper and transfer to fabric). We use the nylons much less so we just keep the...

Not sure how many of you are still using a JV4 but FYI everyone has come up against the temp error you get when you remove a printhead without replacing it with another head. Sometimes you even put in a head that is clogged beyond repair but still has good electronics just to fool the JV4 into...
