  1. Roland VS-540 Black Bad nozzle test

    The pump is only used for cleaning. There's no pump supplying the head during printing, the head just siphons the cartridges.
  2. Roland VS-540 Black Bad nozzle test

    You should check if there is any trace of visible damage under the head. Damage to the head can create a way for the air to get in, and while printing air will slowly replace the ink inside the head. Your problem really looks like air is coming in, although most of the time this happens...
  3. VS540 Missing Colors

    There's one way to be certain that the head is properly supplied with ink. Go for a normal cleaning, the pump should suck a tiny bit of ink through the head, then the head should move left leaving a tiny gap between the head and the cap top and the pump will purge the cap top. If you watch...
  4. VS540 Missing Colors

    The syringe has another advantage, you can feel the resistance. If there's little to no resistance, there's an air leak upper in the system. Make sure the tubes are properly plugged to the dampers. When you pull out old dampers, the lower o-rings can come off and stick to the head nipples. Also...
  5. yellow missing

    Which model of machine is it ? On recent machines (those with DX7 heads), powerful cleaning is not that powerful. You have to do several of those or Sub Menu > Ink Control > Ink Renewal which is similar to powerful cleaning on pre-DX7 Roland machines and will pump an amount of ink equivalent to...
  6. VS-540 woes

    Also as a side note to all VS owners, you should not try to save money by buying the cheaper cap tops from digiprint, those tend to fail very quickly (I've seen some fail in less than 6 months). Prefer the more expensive version which are original roland cap tops and can last several years.
  7. Need Help versacamm vs 540i print head leak and capping station not springing back

    To put the spring back into place you have to remove the two horizontal metal rods holding the upper part of the capping station (the black plastic part) to the rest. These are held into place by black plastic rings on the front and the back. If you remove the back plastic rings you can then...
  8. VS540 Missing Colors

    After changing the damper, did you make sure that you locked the part holding the dampers into place on both sides ?
  9. Roland VP-540 Cyan overspray

    That is a head issue and a common one if you're using Bordeaux inks.
  10. Roland VG-640 Test Print Colors are Off

    I just went across the exact same result today. The printer needed a limit position initialize and flushing position adjustment. Your dealer or service tech might help you doing those adjustments.
  11. Roland SP-540v Printing Issue

    You should also check the state of the pinch rollers.
  12. Anyone Seen This Test Print Before With A Roland?

    Hello player. Did you intervene on the heads ? That usually happens when you spill ink on the flat cables or heads during a head replacement or if the head flat cables are improperly seated. Even if you did nothing inside the head carriage, I'd advise you to check the flat cables on the black...
  13. Roland RF-640 will not print

    Hello Billy, If some ink dropped out in the bottle and you still don't have a single nozzle firing, then you might want to check (or have somebody check) the fuses on the main board. If one of those is blown then you might be in for a head + fuse replacement and/or a main board fix/replacement...
  14. Need Help F2 fuse

    You can check my answer in the other thread you opened there F1 Fuse blowing. Now that I've read this thread I might add that the transistors on the main board are probably blown.
  15. F1 Fuse blowing

    When the fuse blows, that means there is one or multiple shortcuts down the line. This can be on the main board, in the flat cables or in the head. You should never expect to fix it by only changing the fuse, you might just make things worse. If the fuse blows without prior human intervention...
