Magenta gradient issue

[SIDD]

New printer running ECO Solvent-single head-DX600-4 colors (CMYK) with Maintop 6.1
Have issue when printing magenta gradient (pictures attached) wont print light magenta because of this colors are off.
Nozzle check is OK. I am completely lost (Newbie to large format printing)

Any help will be appreciated

try making a .pdf with a magenta graient and then print it. your sample print might be defected.
