  1. Head height adjustment on Valuejet 1604

    So replacing just the top ones should be a lot easier than the bottom ones. It shouldn't need as much dismantling. Since we have gone into lockdown from today I will get some bearings ordered and install them next week. SC
  2. Head height adjustment on Valuejet 1604

    Sean The bearings have become slightly noisier but their is no tight spots, errors or choppy/sticky areas as you move the carriage across. I would of thought after 13 years or use their would be some sort of wear in them though. If the tension springs had gone soft I would of thought that the...

  4. Head height adjustment on Valuejet 1604

    So is it possible to just buy Eight 4x12x4mm bearings and install them into the existing carriers? I thought some of the lower ones are pressed or clipped in on a holder? Thanks SC
  5. Head height adjustment on Valuejet 1604

    Well I tried to adjust the head height today and I cannot get anywhere near 1.3mm on low settings. Probably set at about 0.8-0.9mm . Is their away of lifting the head manually to a new datum point or is this due to my lower head bearings being worn? Thanks SC

  10. Exporting JPG/BMP Problem

    When exporting a file as a JPG/BMP it can take 5 minutes to do. Size is A4 @ 350dpi. Has anyone come up with this issue? It does this on a couple of our signlab stations. Thanks SC
  11. Colour change on VJ1604

    No it wasn't a heavy coverage in fact it is a very light image. Most of the image is a very light grey scale. It was as if it had a magenta tinge to it.
  12. Colour change on VJ1604

    I printed a number of full panels for a wrap onto a new transit L3 H2. I have noticed a slight colour shift on one panel. Each panel had a nozzle check to check that all the nozzles were firing before printing. The colour shift is very very slight but is across the entire printed area. Hopefully...
  13. Carriage bearing replacement on Valuejet 1604

    The question was "How do I replace them?" This looks quiet an intense job and due to never have done anything like this I need guidance. Cheers SC
  14. Carriage bearing replacement on Valuejet 1604

    This is a 2007 machine and has printed Thousands of Metres of print matial and banner. So it hasn't done to bad has it? The way Mutoh instruct you to lubricate the carriage bearings is not correct (This has been discussed on this forum before) as they are sealed and adding anying lubrication...
  15. Carriage bearing replacement on Valuejet 1604

    Well after fitting yet another maintenance station into our 1604 the test print is showing no blocked nozzles and prints as good as the day it was installed. It is now Seven and Half Years since I had a new print head installed and firmly believe that if blocked nozzles are attended to when they...
  16. VJ 1624 Red

    I think you have found the biggest issue with a CMYK 4 colour printer. Reds, Greys, Burgundy, Greens, etc. Just to name a few are a pain to hit. To get a decent colour match on these I will set the profile on something like 3M Ij180 as this prints the maximum resolution of my machine...
  17. Mutoh Multiple Hardware Problems

    New print head, cables and a maintenance station. Then recharge with new inks. If the machine has been left like this for sometime you will never get the magenta back. These machines should never be left with blockages or non use as they thrive on been used and the more you use them the less...

  19. Yellow Contamination Noz Check

    Looking further all your nozzles do not look that well (of the ones I can see). The biggest issue and major factor I see on these printers is lack of use. If not used they tend to block up and you loose nozzles a lot more easily. SC
  20. PVC free adhesive films

    I'm using 3M 480c as in the UK 3M are trying their best to remove their PVC materials. Only thing is it is a big big secret what these materials are based on and will only discuss them with third parties (your client/customer). I reckon these materials will in the long run be more expensive to...
