Did he change the dampers as well when installing the new head? If not, it could just be a bad damper. I have never seen a head cable cause a single channel to not fire and I have been a field and call center tech for ten years. One channel not firing usually means ink flow issue such as a bad...

Unfortunately there is only a couple ways to figure this out and that is to have someone try to diagnose the boards or replace them to see which one fixes the issue. It's most likely the main board because it's the board that distributes the power to the other components.

It will start up like new from the factory so you will need to adjust the parameters to tell it it is full already and then you will have to run the head alignments and adjust any settings you setup manually like blade force and speed and heat settings etc. Unfortunately I don't have the...

I have run into a similar issue and unfortunately it's one of those that could be a couple things and is kind of illusive why it happens in the first place. One thing I would do to rule it out is just do a factory reset. This will require the original parameter file from Mimaki which you can...

As a fellow suppler we are of the same opinion. When we have a demo machine in the show room we will very rarely use it to do a trade with a neighborhood business. One time we made parking signs for the mechanic behind our building and got oil changes in return. One time it was the Sushi place...

Exactly. We always recommend our customer use OEM cleaning solution because you literally can't go wrong with it. I have experimented with it and a lot of time the ink coagulates with non matching solutions.

When it goes to the left side of the machine does it look like it tries to move to the right and then gives the error?

Power supplies rarely fail and it's usually the main board that causes issues like these. I don't have a lot of experience on that model when it comes to power failures but when it happens on Mimaki and Mutoh printers, it's usually the main board is fried. Do you know how to test a power supply...

The shot answer is basically you have a short in the print head signal somewhere. The way this machine works is the CPU makes the signal that tells the head how to fire but it only outputs a 3 - 5 volt signal which isn't enough to get the piezo crystals to vibrate hard enough to push the ink...

They test and then fill these heads with an aqueous solution. It is normal.

We don't do it this way in America so I don't have any experience with it but I would assume Mutoh needs to get the mpi file so they can send you a ULK file back. The dealer wouldn't have access to that usually. The way we do it here is when you register the printer, it gives you a code and you...

I have a used JV33 main board that you can convert to a CJV board if you have the proper jumper and firmware. Feel free to email me to the email address in my signature if interested.

Since it's not full time maybe the pigments are separating from the solvents which causes the ink to be much less viscous which causes over spray. This is not something that happens a lot but in your case might be true since it doesn't get uses much. Before you go buying a head a would flush the...

That actually means 3 million thousand fires. So you are actually at 3 billion fires. What kind of ink do you use? Maybe you got a bad cyan cartridge or something. Head life really comes down to how well you maintain the printer, using quality inks and plain old luck. I have seen guys who clean...

The VP540i uses 4 inline DX4 print heads which each have 2 channels of 180 dots. That's 1440 nozzles. The SolJet Pro 4 uses 2 inline DX7 print heads which each have 8 channels of 180 dots. That's 2880 nozzles. The Soljet EJ-640 uses 2 staggered DX7 heads with 8 channels each of 180 dots...

You can run full solvent inks through those heads they just won't last as long.

What happens? Do they just not open or do you get an error code? A lot of times you might not be able to open a file due to lack of memory but the RIP processes the file in a way that memory shouldn't be an issue to RIP it but it will slow it down. So usually you can RIP a large file without...

As everyone above has stated, heat assist has very limited applications these days. Mostly because vinyl manufacturers have perfected their adhesive formulations to prevent silvering. That being said, heat assist is a necessity when laminating UV prints.

Forgot to add the link. Yes that is the correct one. We send the tech manual and give phone support if you get stuck or have questions. It can be hard to decipher the manual sometimes since it wasn't originally written in English. There are also YouTube videos out there but be careful because...

The dampers are fairly easy to change and is actually part of changing a head out so it's good experience. Here is a link to the part on our site. Your machine takes 4 but luckily the black shares a damper so you can only change just the black one to rule it out.
