  1. Mutoh vj 1204 pinch roller replacements

    Why did you replace the pinch rollers? Was everything working fine you just thought it was time, or did you have feeding issues?
  2. Mutoh 2638 Service Manual

    Did you ever get the service manual for this printer? I've got two and would love to get a copy of it. I'm planning to do my own maintenance, but just need to know what to do. I've had one machine 1.5 years and one 0.5 years. The first is already past 6 billion fires and the second is around...
  3. Strange Noises from Mutoh 1624

    What did this noise turn out to be? My VJ-2638 has just started making a similar noise at the maximal distance from the capping station.
  4. Profiling in M1 mode with a polarizing filter

    Would you please elaborate on what I've misunderstood? It's a significant effort and cost for me to profile as I'm working with sublimation - so prefer to be best educated before doing it again. My stock is a textile that contains optical brighteners and is always viewed outdoors where UV is...
  5. Profiling in M1 mode with a polarizing filter

    I have an i1Basic Pro 3 Plus and I need to profile a textile that has a bit of specular reflection when being measured. I know that M3 mode can be combined with the polarising filter, but I don't want to profile under M3 mode because it cuts UV from the light (and the effect of OBA's) for...
  6. Is this a sign of my printhead(s) dying and needing to be replaced

    Let's try that again. I can show you a nozzle check but there really isn't anything to see there, it's complete. It's a VJ-2638X
  7. Is this a sign of my printhead(s) dying and needing to be replaced

    Hi All, My printer, particularly in the cyan channel (but also a bit in black channel), produces these vertical (perpendicular to the print head travel direction) bands on the left in the print now. Don't recall it ever doing it before until recently. I know it looks like shadowing, but I...
  8. Vertical banding on radial gradients

    It's the profiles that were created when the machine was installed back in March. Been using them without issue, but to be fair we probably don't print many gradients. It's just this one job that's come through now. This is a pure vector gradient. It's made in Illustrator. I tried to re-do the...
  9. Vertical banding on radial gradients

    How would I enable perpetual rendering in Onyx? I mean, exactly what is that feature? Anyway, here is some photos / videos: - Photo pack can be downloaded here: https://we.tl/t-DRfoEd0AQB - Video of poorly printing gradients in Onyx: https://vimeo.com/773159706/1365161f81 - Video of...
  10. Vertical banding on radial gradients

    I get these same bands (perpendicular to the print head movement) in light colours like pinks, blues, creams, and yellows. I also use ONYX and am thinking that it's the RIP. The blue for example is just a light light blue 15/1/1/0 and you can see magenta "banding" through it. It's super odd...
  11. Mutoh maintenance station / Cap top?

    Rat_Fink, any updates here on what you did to resolve the issue. I basically have the same issue with a VJ-2638 where doing a clean ruins the black channel (introduces air into it, so half or more of the nozzle drop out) Many cleans struggle to resolve it, often I need to resort to a little...
  12. Black channels filling with air during/after a clean - Hard to clear, resort to Little Charge. VJ-2638 Sublimation

    Thanks for both responses, they're excellent. Where do you both think I should start chasing this, in order of easiest to hardest / cheapest to most expensive. The annoying thing is that this issue has been presenting basically since I bought the machine. It was first inked up in mid April...
  13. Black channels filling with air during/after a clean - Hard to clear, resort to Little Charge. VJ-2638 Sublimation

    Hello All, First time poster, long time reader. Looking forward to becoming an active member of the community. I have owned a VJ-2638 now for about 8 months (received in Feb, inked up in April). I print paper and sublimate with it. It is inked up with Kiian Hi-Pro ink, and a Kiian bulk ink...
