  1. Mutoh valuejet 1324x ink dropout? (please help)

    Hello signs101 guru's, im having very odd problems with my mutoh valuejet 1324x. i was having 1 in streaks of pink/magenta at the start of my prints and pretty bad banding (pic with the pink and banding) i ended up switching out the dampers and maintenance station. the problem persisted...
  2. How many colors should there be in each damper?

    My 1324 will barely print anything at all. I removed the dampers and CMY have 2 colors in them, and K is solid black. K also prints the best. But I am using a lot of C&Y to print some custom Ukrainian flag designs. Is that a problem with the dampers? If so, is that all I need to replace? Does...
  3. Is it time for a Damper change??

    I have a Mutoh valuejet 1324. It’s dropping ink (cyan) after a couple feet of printing. Is it time to change Dampers? My nozzle checks are 100% perfect and the Printhead is 5 months old. thanks
  4. Mutoh VJ-1324 not charging ink

    I replaced the maintenance station and dampers along with the joint going into the Y cartridge holder because it had a leak. Now none of the ink will charge. I've tried many times, both normal and little ink charge and several cleanings. I can pull ink to the head with a syringe but it starts...
  5. Question What is the Purpose of Dampers in a Print Head Carriage?

    It's just a basic question about what they are supposed to do. I am curious to know the function or purpose for the dampers that sit above the print head, and why they would need to be changed a regular intervals? They look like little tanks with baffles and don't appear to have any moving parts...
  6. Rant are all dampers created equal?

    are all dampers created equal? Why does Mimaki use the tall dampers on a dx5 head, and Roland uses the small side by side dampers, and Mutoh uses the dual channel dampers? All are "based" on the same dx5 technology but everyone has a different theory... I am a little crazy so I might just try...

  8. Need Help Black Ink Drops Out Slightly While Printing (Damper Problem?)

    If black ink is slightly dropping out while printing but the test patterns are perfect would you say it is because of the dampers? How often should I change Roland VP-540 dampers? I just replaced the Wipers and Caps are all new. Here is the pictures of an image I printed in versaworks with...
  9. 1614 Dampers

    In the service manual it says to fill the new dampers with cleaning solution prior to installing. Also says to do a head wash to empty the ink lines/dampers prior to removal. On the 1604 I did not do this and wondered how different the 1614 damper procedure is. Any tips on replacing these would...
  10. Help

    Does anyone know what this problem might be, I'm refilling my JV3 with ink and only my cyan, lt cyan and yellow is coming out on the test print. I tried drawing ink from the back of the printer and from the damper still can't get it to fill the dampers, even on new dampers.
  11. Calling mutoh gurus! Help me please

    OK so I recently rebuilt a toucan lt 64: flushed printheads, replaced lines to pumps, and replaced ink lines from the metal lines to the dampers . My question is do I need to prime the ink at the dampers or will the pumps prime the ink? I don't have a manual so I'm not sure how to get to ink...
  12. Mutoh troubleshooting

    Hi everyone, My name is Ludo, I'm from Nouméa, New Caledonia (Yes, I'm a Frenchman!) and I'm having some trouble with my Mutoh VJ 1604 since it doesn't spit ink anymore!!! the print head isn't clogged though and my ink lines and dampers are full... I think it must be some electronic problem...
  13. Color dropping out on Mimaki JV33-160

    One of the yellows keeps dropping out randomly while printing. At first, I assumed it was caused by air in the lines somewhere. So I syringed it and it would work for a time and then drop out again. I then replaced both the yellow dampers. Problem still happened. I just tried swapping the...
  14. jv33 empty ink line issue

    Hi everyone. Today my one of my cyan cartridges ran out and because the ink level sensor turned out to be broken, it bled the line dry (presumably both cyan lines as they are connected with a T just after they leave the cartridges). The cyan cartridge light is green so there dosnet seem to be a...
  15. Epson GS6000

    Run a test print / nozzle check and getting zero on the media. Ran cleanings and also manually soaked to head at an attempt to removed any clogged / dried ink in the heads. We have taken apart the front of the right maintenance station to gain access to the pumps to see if their was a clog and...

  18. Roland XJ-740 won't sense Right Edge of Material

    Hey all, I have two issues with my Soljet XJ-740. Issue 1 First is that the material sensor will not sense the right edge of the material. The Roland XJ-740 will no longer sense the RIGHT edge of the media. It constantly picks the exact same position on the RIGHT side no matter where I put...

  20. When is a printhead dead?

    Hello, Yesterday I replaced 12 dampers on my Roland SC-545EX for the first time by myself. I took the time and did everything very clean and carefully. When I was ready I did a test print and many of the LightCyan nozzles didn't print. I did a cleaning on the C group and got some nozzles back...
