Mutoh Valuejet 1304 - Need advice, please!

[Design Guy]

I bought this printer almost 2 months ago. It appears to be in great shape. I did not actually print with it for about 2 weeks after I bought it, but I did keep it plugged in and ran cleanings and nozzle checks daily.
My initial issue is that the yellow in the nozzle test was almost non existent. So I tried several head soaks and replaced all cartridges with Mutoh brand cartridges.
So I ran a test using a full color comic book cover and it seems as though the print is worse than when I started the head soaks initially. I have done this several times.

Ive attached a pic of what the original image looks like and what my print looks like.
Please take a look at the photos and let me know what you think!

Thanks!

What does the nozzle check look like? My guess is you need a lot more head soaking

Hey Mike. The yellow lines in the nozzle check are very faint. The other 3 are not bad, though.

Well, yellow will always be faint on white vinyl Do you have all the nozzles though?

If your yellow nozzle pattern looks pretty good, then....

try doing this... go into photoshop, go to the color chooser and and in the CMYK numbers, put in 0,0,255,0 (full yellow). Then draw a rectangle, say 50" x 2' (assuming 54" media), and fill it with the yellow.

Now save the PSD and then print it. Watch and see if your yellow starts to come back. You may have to print this numerous times to get your yellow back to normal
