Need Help Need Advice Replacing Mimaki UJF-3042 HG Ink Damper

Hi Guys,

I'm new to Uv Printing, only started about a month ago. It's been an interesting learning curve adjusting to Raster Link. Had to make a couple of mistakes, trial and error to learn quickly with the "live" jobs that had come in. Im enjoying it so far.

I bought a 2nd hand 4-year old Mimaki ujf 3042 hg uv printer. We did a nozzle test print and the Cyan is misfiring. The technician also mentioned the same issue and asked to change the ink damper for the cyan. Ive done a couple of prints, auto cleaning, manual cleaning and the issue still persist.

I'd like to attempt changing this on my own by purchasing a damper online.

There are no instructions on changing this, well at least not that I can find any. I don't want to damage the carriage so could someone share instructions, videos etc on how to access and replace the damper.

Thank you guys!

 

Hi Tipgypsy,

The "lines" or nozzle marks printed by the cyan have missing gaps when printed. So it still prints but not completely.
Also when I did a simple printout of a solid cyan rectangle the output isn't a solid block, its a faded print - which brings me to think that the cyan is firing but not consistently due to depressurisation caused by the damper.

What are your thoughts?

Thanks
