Need Help Mutoh426VJ Problem! Overprinting Cyan over colors (Allways)

[juaan]

Hi, all, im from Argentina. I was using the machine (Mutoh 426VJ uv printer) without problems, until suddenly it started to print cyan on top of any print. It prints the colors correctly but always with a layer of cyan on top. Can someone help me out? any clue on what it could be ?

Here a Nozle Check and a color disk print.

Thanks in advance !!

That looks like a deffective print head or head cable.
Sadly more than likely the print head.
Ours did this and was covering everything in magenta when the head failed.

I would replace the head cables first just in case something is causing a short.
But be prepared to change the head fuse as it can blow.

Hey SC, perfect ! I'll follow your advise with the cables. I'm going to watch some videos and tutorials to see how it is disassembled.

And ready to blow the fuse out

Thanks again ! im very new on this.

Check the captop condition first before thinking of replacing the printhead
