  1. Discussion Plotter/Cutter of Choice?

    The HP cutter is a Summacut and the HP plus is a Summa S-One. HP uses a special barcode with the SAI Software, which is pretty user friendly und when you need a printer, cutter and software; the price is nice. As far as i can judge, it should be possible to "un-HP" a HP, or HP a Summa via...
  2. Question HP Latex 300 Calibration

    Sorry for my late reply... If you made the profile (and color reference)on printer A in good condition, you don't need to do a color calibration before you copy it to printer B. You can do it after copying. Of course you need to do color calibrations on both printers quite often, if you want...
  3. Need Help SG-540 Cutting Issues

    Hello Does it happen all the time, or just intermittently? I'm asking, because i have a similar problem with a customer. (I'm certified Roland Tech) With this machine, it only happens once every couple of weeks. I would like to do a test, if it happens on every job.
  4. Discussion I've owned an HP R1000 since April 2019, ask me anything

    Printing on the belt isn't what you should do all the time. I can tell you that, as a R-Series certified tech since June 2018. White ink on the belt will instantly create problems, since the edges of the mediae can't be detected anymore. When a lot ink is deposited on the belt, the vacuum is...
  5. Question HP Latex 300 Calibration

    This won't be easy or even impossible, since different Rips can use different color engines and profiling solutions. HP Latex printers handle linearization and ink limits internally. The more expensive ones have a i1 measurement device built in. The 360 certainly has one and can create ICC...
  6. Hp latex 315 or Mimaki cjv150

    Go for the HP Summa combo. I know Mimaki and Roland printcut machines. I service them. They are ok, but i'd go for latex. Latex prints are ready for delivery or mounting or cutting right after they are printed. Latex 3rd generation inks are more scratch resistant than any ecosolvent inks. Often...
  7. LEJ-640 FT UV Flatbed problems. Ending my silence

    Solution for vertical banding Today i got a reply from Roland Europe regarding vertical banding. They say, that it can only be reduced by using "fix dot". I think this means using only only the large dot size. Unfortunately they say, Versaworks isn't capable to do this. Later this week, i...
  8. LEJ-640 FT UV Flatbed problems. Ending my silence

    Yellow trouble If you haven't already done it, flush the ink lines before you change the dampers. In my cases, the problems started with EcoUV2 ink lot# 5A19D1B101 exp. Oct/18 2016 If you are very unlucky, the filter in the printhead manifold can also be clogged. After using ink from...
  9. LEJ-640 FT UV Flatbed problems. Ending my silence

    Yellow ink What ink do you use? There is EcoUV Ver.2-4. Lately i had some issues with yellow Ver.2 as well. Either they changed the formulation or just some bad batches... The dampers clog pretty fast. First i changed the dampers and flushed the ink tubing. It worked for a while for the...
  10. LEJ-640 FT UV Flatbed problems. Ending my silence

    A Roland Tech Hi all I have been called to a customer with this problem yesterday. (i'm supporting Roland printers, since FJ-50 or around Y2K) It's a standard LEJ, but the cause for vertical banding is highly likely the same. I have other customers with this printer and haven't heard...
