  1. HP700W - how to disable white ink long term?

    We were told our expectations were too high for this machine. We basically need pixel-perfect registration, with no choke. Can I ask what settings you would typically run with on vinyl? I feel like I’ve tried everything, but there are infinite combinations of settings.
  2. HP700W - how to disable white ink long term?

    Okie dokie… is it bad for the machine?
  3. HP700W - how to disable white ink long term?

    Is there a service-side procedure for disabling the white ink long term? Something like flushing the lines, perhaps? I would just like the proper terminology to ask my tech for this. I just can't get this thing to register white to CMYK, at the scale I'm printing. I've put a few months...
  4. Anyone have older firmware files?

    Okay, I reinstalled the firmware like HP said, and no luck. Then I tried a generIc like you said, and that DID work (Thanks!) How did you know? Do custom presets just become corrupt sometimes? There’s no difference in the settings between my custom and the generic.
  5. Anyone have older firmware files?

    No, good idea. I will poke around some generic profiles in the morning. It's for a 700W, btw (Thanks JBurton!) HP also got back to my tech, and said it might not be the firmware version, but possibly just a corrupt upoad. Apparently, it's best to extract onto a USB and update that way.
  6. Anyone have older firmware files?

    I'm trying to verify that a problem developed when I last updated the firmware. I was getting perfect white coverage, and now even when Onyx shows 100 percent spot, I am getting a pattern. It doesn't matter if I choose a mode with 160 percent white, either. Doesn't matter if I choose...
  7. New HP Latex 700 and 800 series - with White ink

    My 700W can be frustrating, but what it does, it does very well. If I’m honest, it probably has fewer problems than the UV printers I’m used to, but it’s a steep learning curve.
  8. HP700W firmware glitch

    Just a heads up for anyone else who might have been excited that the Sep 26 firmware update added a screen to adjust white alignment without require a status plot. It not only doesn’t work, it also accepts the input and keeps the new data, making you think it worked (it even tells you it was...
  9. HP700W tension settings

    Gotcha… or when I overdo the vacuum.
  10. Repeated Reseat Printhead Error - HP700W

    Good luck, and please keep us posted - might need to know :)
  11. HP700W tension settings

    Ah, okay. I did some tests with no take up, and OT setting appears to be irrelevant, so I think that proves it’s for take-up tension. So I assume it’s pretty safe to say BT doesn’t affect printed output, and only needs adjusting if we’re slipping or slacking as it winds back up on the supply...
  12. Repeated Reseat Printhead Error - HP700W

    I am having that with head 10, after no head strike. I even get it when I use the fake heads. I was able to get it to go away by removing and replacing the same head, and on the last attempt that worked, I made sure to press down hard when installing, but that probably just pressed a bit...
  13. HP700W tension settings

    Does anyone know exactly what happens when you change these settings? Here are my theories: -Input tension: controls the tension at the input roller, which is the roller that could be swapped out with a surface cleaning roller, but I can't see just how it would accomplish this. -Backward...
  14. 700W owners: White alignment problems?

    Update: The feed axis spring was just installed today, and I’m told the enhancement kit was never installed either. The tech says he will order it, but no word on when it can be installed. I’m really surprised that these things aren’t installed on all new machines! What does the enhancement...
  15. 700W owners: White alignment problems?

    Just an update. I have tried hundreds of combinations of different tensions, vaccuum, materials, etc. I have a service call in for that upgrade, but to date there is not even an expected install date. Not sure what to do as we need to be able to align white ink (and cutting) to the CMYK...
  16. 700W owners: White alignment problems?

    Okay, here’s a quick video:
  17. 700W owners: White alignment problems?

    Wow! I asked my vendor, and the tech agrees with you. It is NOT installed. They’re asking HP now. Thank you so much!
  18. 700W owners: White alignment problems?

    We tried an alignment, and it fixes the issue at the leading edge, but then it still deviates in all directions as the print continues. Tried a few different stocks, with no change. I’ll take pics as soon as I try a few more things. I want to make sure I truly isolate this issue. Next...
  19. 700W owners: White alignment problems?

    Thanks guys… I cleaned the encoder strip as well as I could, and tried the print zone temperature at 37 and 45, with low and high airflow. These were great ideas, but no change. Any other ideas? I am still trying different tensions and vacuum settings, but no effect yet.
  20. 700W owners: White alignment problems?

    I had a feeling it was something like this! We’re already at minimum, so bad news for me!
