Hello
I'm having a little problem with my Roland SC 545ex

I had problems with a light cyan head (dried head) so I took my head out and let the eco solvent fluid pass through the injection. Then I put my head back. I also bought new head cables. I let it run through a few powerfull cleanings to make it fill up with ink. Worked perfect! It pumps ink from every color from each head.
Now my problem is: I made it print a nozzle test and it prints cyan, magenta, yellow, black but it doesn't print any light magenta and light cyan. (picture below)
I thought there was something wrong with the cables, so I replaced them with each other, and now I'm left with no yellow and black
maybe somebody knows what could be wrong

Practicing expensive printer repair without training :)

You may have wrong/misinstalled/broken cables, fried fuses and/or electronics there.
