I'd do the print length compensation in Flexi and see if it works. It can be more of a band aid but if it consistently fixes the issues and doesn't need to be adjusted every time you print, it might be worth trying.

Yeah basically anytime you see lines like that it's going to be missing nozzles or a print feed issue.

Looks like you're probably missing nozzles in your nozzle check. Did the person you bought it from train you on the maintenance of the machine at all? There's a few basic things you need to do to prevent the nozzles from clogging. It's possible it needs a new cap top as well.

You can expect to be +/- about an 1/8th of an inch on prints that long so a whole inch is out of spec. Do you see any sort of distortion in the print? Any banding? If you scroll the material forward using the buttons on the panel, do you hear any thumping noises?

It's most likely a failing head but you can try changing the head cables out to see if they're causing the issue. What does your nozzle check look like?

The newer MS31 inks dry faster so it can dry faster in the maintenance parts as well. They came out with a modification to the waste tubes to prevent the clogging and you can flush cleaning solution through once in a while to prevent it as well. At the end of the day I've had many customers...

You will need a laminator with heat assist to allow the laminate to conform with the edge of the ink. I have heard of some people using certain laminates that work better without the heat assist as well so hopefully they will comment.

You should be able to see ink flowing through those lines during the pump cycle. The fact that you pulled dry ink out of the tubes means they are probably clogged in other places. I would disconnect the tubes from the cap top and try to push cleaning solution through the pump and into the waste...

The pump tubes connect to the two nozzles that are right next to each other and the air release tube connects to the 3rd, offset nozzle.

On the 2 headed machines you can choose to print with one head but the Super Fine Wave A or B works with a single head. Basically there are 2 channels for each color and choosing A or B chooses which set of channels to print from. So it fires from 4 channels instead of all 8 which does cut the...

If you have a Mutoh ValueJet and are only using 4 colors, there is a mode that allows you to choose to print with only the A or the B channels which can help if you have one channel giving you problems. It's called Super Fine Wave A or B and it of course slows the print down a lot but it does...

Haha! Luckily I don't work too much in the field anymore. I'll let my field guy know though!

That's a good observation because light colors don't add gamut but they do reduce graininess! You need a color like orange or green etc to improve gamut on CMYK printers.

Signs365 prints with Latex machines for their vinyl products and they print at a fairly middle of the road resolution so they can pump stuff out all day. If you want to be able to do fine detailed printing, get anything with an Epson head in it like the Mutoh VJ628, Roland BN20, or Mimaki CJV150...

The VJ628 can print up to 1440 DPI for sure. It has the exact same head as a BN20 in fact.

As a tech whos been in many sign shops around the country big and small I can tell, your employees are doing side hustles behind your backs all the time. It is common for an employee to pull me aside and ask me to work on their machine after work. I'm not saying I agree with it but it's a dog...

We used to do this when we had a good supplier of the aqueous ones. The trick was to flush the head with a water alcohol solution first, then flush that out with air, then flush with solvent solution, and air again. That seemed to work the best although every once in a while we would have one...

Mutoh has some 24" desktop solvent printers similar to the BN20 just without a cutter. Looks like the Roland is priced better though.

The only way you can get that particular cartridge to work again is getting a new chip. I would also take a look in the cartridge holder with a bright flashlight and see if any of the sensors are broken. There's a little plastic lever in the back, bottom, right side of the holder that if broken...

As a tech when I heard there was an XY slitter on that model I thought, "Cool! That's going to be a nightmare."
