Great videos! How do you clean the ink lines at the damper end? I try to draw it out without the damper on and nothing comes out of 4 lines. (2 magenta, yellow and maybe light cyan) I replaced all my ink lines when I switched from white/silver to cyan/ magenta but I still had problems. Unfortunately, it sat for the last 6 months (kept getting error code 0109 and spotty inks). I have continued to keep the head soaked so I believe that is fine, I do not have the choke installed any more ( the tech when he replaced the lines disconnected it) but all the parts are there if I need to reconnect.

[@reprint217]

Have you pulled your lines from the ink needle? Possibly the needles are clogged in the cartridge bay

[@reprint217]

Also, I have had machines with the choke valve bypassed, have seen this many times and be very careful when messing with the head. I choked one off and assumed it was choked and destroyed a brand new head.

@@reprint217OOOHHH! I never thought of that!! I will check. Thank you!

@@reprint217 unfortunately I do not have anything small enough to go over the needle. Do you have a suggestion for the tubes that attach to the damper top?

Hi there, I have a roland XR640. Yellow just drop off on one head, all the other colours are like new... Had damper changed. No difference. Any suggestions? It was fine during a print, then it drop off on the next set for about 2 lines of stickers, then came back 100% on the 3rd line and then on the next set it just stopped again. No yellow on the damper after normal cleans, yellow comes thru little on the powerful clean, but no yellow at all on that head on test print.

I am having the exact same problem on the #4 Magenta Channel. Just stopped and showing sections in the ink tube with no ink.

@@creativesignsolutionsinc.5866 urs may be ink starvation issue. Have u at any point bent the clips on the ink cartridge just to finish a job in an emergency then put a new cartridge the next day?

no I've never done that. I actually identified and solved tbe issue. the choke valve went bad and I just bypassed it...

[@estebanhernandezfernandez1278]

I have one problem in my Roland VS540-i. The head has already been replaced but it still has problems with the black line, have you had a problem like this. I thank you if you help me

[@reprint217]

Story of my life. When replacing a head, it either goes smoothly or terribly wrong. Sometimes its aftermarket dampers, they are hit and miss. Choke valve issue, ink tubing getting air... so many possibilities. It's really just narrowing it down.

thank you very much @@reprint217
