Print quality issue

Hi there. Getting this. See photos. Oldish Mutoh. (running via ColourGate). Horizontal lines. Trying to do a high end sign. It will be viewed close up. I know I can fix by uping the ink (say going from 8 pass to 9pass).
but this will obviously make it darker and customer has already ok the colour. I have tried different media, with a small amount of success. The photos are a gloss 5year vinyl. Any thoughts? I'm sure there is a setting ( either on the Mutoh it's self or on ColourGate) even if it does not fix completely? but anything that would help would be fab?. thanks Simon

We had this issue on our new Latex. In the end we had to do a manual calibration for the media. (after unnecessarily replacing printheads, countless alignments and cleans.)
Fixed it and no more issue

umm, bit loathed to do anything this drastic. Last time I did something like this I touched the head and ending up having to throw my machine away :-(
(I didn't realize how delicate the heads are, as you can tell I'm a newbe to wide format solvent printers) I can't seem to find a power clean function anywhere.
Its a Mutoh VJ1324. thanks for your advice.

That's fine if you're not comfortable with it. It is unfortunate to hear about the other head going bad. A head soak shouldn't involve any touching of the head plate. Just filling up the cap top with cleaning fluid then parking the head back on top for a soak.
If you're concerned only about this particular job/print, just crank up the passes and try a small test print for colour matching and hopefully you can get something passable.

I know our Roland used to suffer from dropouts when the cap top was getting old. We used to swap ours out every 3 months instead of the recommended 6.
In saying that, we've never changed one on our Epson in 4 years, and it still prints flawlessly.

Ok have done what has been suggested here (in red) so many times. Almost know difference

https://techsupport.signwarehouse.com/cleaning-clogged-nozzles-on-value-jetprismjet-printers/

But having said that this video is not very clear, maybe I'm cleaning the wrong area?. I have used heaps of cleaning fluid. Fab if someone had a link to a better/clearer video.

I have an identical Mutoh here (just for parts) How hard is it to swap this whole area out. (see photo), just a thought?
