Looking for a Mimaki tech

[tcorn1965]

That services Davenport, Ia (Quad Cities). Please PM travel and hourly rate. I have no spare parts in house.
JV3-160 SP Left channel of cyan is barley there during nozzle checks.
Best guess it is the slider board. Here is what I have done so far.

• Replaced Dampers, O rings, Manifold, and Head cables.
• When I did the data cable swap at the slider both channels were there, looked odd though, cyan printed over yellow, and there was a blank swatch? Which makes me believe the head is good?

Thanks,
Terry

the misplacement of the print test is due to the y coordinate assigned to that slider port. it still thinks it knows where the head is. so that is not an issue. when you did the data swap, did the cyan print properly from the new port and the cyan data cause the new head to miss. ...it doesn't look like it. it looks like you've got a vacuum issue at that head. the head is now drying out and badly deflecting. if it's a cap top issue (might be) and you have the detachable cap tops, just swap a top with a functioning cap top in order to isolate. also look for a clog at that cap tube. many times a clot forms right at the base of the cap top. you won't be able to see if from the back. before you get a tech out, i'd have someone dump cleaning solution down that cap, while you pull at the waste line aggressively with a syringe. make sure you've got good suction by pulling with the head parked from the waste line (you can hear air leaks when pulling with a syringe at the waste line. the pumps are too noisy to notice). get a good read on the caps, then do a head soak. if you get any improvement at all, you just need to continue cleaning.

Artbot I was hoping you would chime in...Thanks. When you say detachable cap tops, I don't know if it does or not. How do I tell if I have the one with the removable screens or the newer one thats more of a one-piece design?

OK, I did that, and a 99 min nozzle wash, does not look any better. Thanks Artbot. I guess I will need a tech, so any tech that service my area please PM me travel and hourly rates.
