Mimaki UJV100-160 ink issue

[tkhandsome]

Hello,

We have a relatively new printer. It has been working well for a bit but now we’re having issues with the black ink not firing correctly.
Our black ink is turning out green.

When we do our test print the black ink is smudged.

Any thoughts?

Black is usually printed using all colors for 'rich black' and missing black nozzles will make the black look weird.

Understood.
Any idea why it’s smudged like that?

That's nozzle deflection causing over spray, added to that you've got a fair chunk of missing nozzles in the black and magenta, have you had a head crash recently ? Looks like the head's in pretty bad condition. You could try doing a captive wash followed by a powerful clean.

Any idea on how to clean it?

I wasn’t given much training on this machine. I’ve had to learn this all on my own.

If you haven't already, try doing a nozzle wash.
