1324x damper changing instructions

[Keevan]

Good afternoon,

Anyone can provide me with exact detailed instructions on how to change the dampers on the 1324x correctly?

Do the dampers need to be primed with a syringe?

I have attempted to change dampers and used digiprint generic types but always I end up with missing nozzles. i have tried 5 sets and no luck. If the problem is the damper then as many members have saif that generic dampers do not work at all, I will purchase a set of original Mutoh dampers.

I would then like to follow the instruction manual exactly as the original Mutoh dampers are not cheap and I don't want to risk damaging them.

Thank you very much in advance for your assistance!

You have to rewove the head to replace solenoids (Mutoh calls dampers this). When removing the ink lines turn clockwise. Be very careful you don't drip ink into the cables or the head.
No don't prime them just do a little charge.

Thanks for your response! As I said I have attempted it before by apparently its not my technique it is just the generic dampers that can't work for whatever reason...

A technical service manual would be appreciated also if anyone has it!

Nowhere in the service manual does it say to pull the head when changing the dampers. Now when replacing the head, that's the time to replace the dampers as well. I'm getting ready to swap digiprints dampers with the 13 year old Mutoh originals that have finally wore out. I'm missing a bunch of black nozzles in the left quadrant of the nozzle check patterns, less than 5 yellow and two magenta. One thing I've learned through this preparation has been following advice from Mutoh. They say once a year to replace dampers and the maintenance station for a normally used printer. Also take out the cartridges periodically and shake them. Well, the plandemic messed it all up, left me 130 miles from my shop vacant. I'm a small fish in the sign business and I normally don't use my printer for months sometimes. I tried head soaks, and they help to get up and running for about 3 to 6 panels of 10' printed photos. Time to dig in...I have been given advice from several techs and am about to do the job, probably in a couple of days.

Please see attached screenshots, when using genuine Mutoh valve dampers, you need to flush them with cleaning solution before inking
