Print heads CAN fail in 2 years. These are mass produced super sensitive electronics. Epson may not be making these heads like they used to, your mileage was not usual on the original. When you got your printer originally, epson was still putting those heads in many printers, including ones...

Crazy is putting it lightly. Appreciate it!

Yeah, I’m not the biggest fan of how they implemented it all, but I do enjoy the little air purge plugs that disappear like a bad father. Sweet, let me know what you dig up. The carriage is modified to about 3x head height to generically avoid head strikes. This is ran on the UCJV, so there’s...

Definitely not total delams. More like regular head strike nozzle loss replacements, or the yuppy folks that won’t up a pass count, replace it. Mild electronic failure where there’s overspray that can’t be accepted on vinyl disappears on the sandpaper. This is a 1.5 year old set of heads. Head...

So, like the title says, I want your old/decommissioned Mimaki UCJV300 / JFX-XXXXex print heads. We print anti slip tape. It’s a head strike nightmare, but the gritty, grainy surface allows us to use heads way past their usual life expectancy. If all channels still fire, I want it! I will...

Post your nozzle test. Also retry this on unidirectional (in versaworks) to verify if this isn’t a bidirectional issue. How old is the machine?

That’s the risk you take. Not to say that you can’t dig up a head that’s wasn’t abused or was pulled and responsibly flushed from a water based machine, you certainly can. But it’s 2024, the risk isn’t the same as it was 10 years ago. A clean nozzle test doesn’t tell the whole story, so a “it...

There’s really no such thing as a refurbished Epson DX head. Refurbished implies there’s something that can be freshened up. There is nothing about these heads that can be tuned up, ready for a second home. Either it was retired because of age or failure. A blocked head that’s flushed for...

Is your ink date? What ink are you using?

I’m sure you can find a LEC540 or LEC2540 used in your market. Epson heads, no crazy ink wastage, both can do stacked clear. The UCJV330 is a great machine and isn’t a tinker toy like the 150 or 300, and doesn’t have the “be our test subject” ink wastage issue like the LG does.

Sounds like it’s time to get out and into something made in the last decade. Market is real fluid right now, people are giving away CJV’s.

That was going to be my concern

Did you unplug the printer before installing the new head? Sounds like you blew a fuse/board, or incorrectly installed your head cables.

Did you replace cap and dampers with the head?

6 years is already strike number one. Strike two is constant nozzle washes and head soaks. The solution breaks down the nozzle plate adhesive over time if overexposed. This more than likely isn’t the cap.

It’s a 5 year old head, it’s probably toast.

UCJV is the older of the two and is a workhorse.

The valve head assembly is a damper. White is your far far left one when facing the printhead. I am in a tech in the Midwest. I have replaced dampers on a 661. It’s annoying. There’s a cage around the dampers, all ink lines have to be removed, it’s a pure gravity fed machine, meaning those...

Depends on if they’ve fixed the ink wasting issue.

Been playing around with this stuff as well, flexi complete would/should allow you to profile with from what it looks like all or most of the x-rites. Have you downloaded any of the profiles from the Mimaki profile center before jumping into this extra expense rabbit hole? Wouldn’t hurt to...
