I'm thinking the easiest solution would be to dump the MK ink and fill that tank with distilled water and maybe a little alcohol. No way would it clog up the valve, unless some residual MK in the line got loose. I don't know about leaving the red-colored Piezoflush in the MK tank as it might...

Interesting idea! I have a PK/MK 3880 valve (A new spare.) and it has four ports on one side and two on the other. I don't know what Epson is doing with that many lines (Six?) in and out of the thing. It's a bizarre looking thing, and Epson wrapped it with some protective tape over the two...

hmmm... Maybe solvent related too. Dunno. :idunno Anyone take one of those PK/MK valves apart to see what goes wrong with them? Plugged up with ink crud, or maybe etched by some solvent? W.F.

That's already a given knowing how many have had issues with that valve and the idiotic design behind their PK/MK switching system. I often think Epson designed it to waste ink with subsequent sales of more ink to feed it. So far, the issues I've seen with that shuttle valve and its design...

Which is guilty? The Photo Black (PK) or the Matte Black (MK) ink that damages the shuttle valve in the Epson printers. I'm guessing it is the MK (Matte Black) maybe being a thicker ink doing the damage to that valve that switches between the two. If so, I'm thinking of maybe switching it out...

I just rinse mine out with tap water and blow them dry. I keep them all in a Tupperware container too for storage. I also use a bar of "Lava Soap" to get the ink off my fingers which seems to work well being it is a pumice-based soap. Found it at a hardware store as most drug and grocery do...

No doubt you have some of those "Epsonus Hidenesis" worms residing in one of your two capping station drain hoses. I had two of them in this post that shows the photo of them both: https://www.printerknowledge.com/threads/how-to-go-about-flushing-all-ink-out-of-a-3880.12502/#post-107859 I was...

It takes a lot of fluid to get the lines clear. I must have run about 6 power cleanings to finally get all the cleaning solution to the head and begin to clear in the capping station pads. When I did the two pads on one 3880, I left the print head off to the left and kept flushing the pads...

I'm not fond of ammonia due to it being corrosive to some metals. I am interested in the Ranger Industries alcohol ink though. Maybe a mix if it with your alcohol in a cart and trying to use the magenta color patch to print. Mine took about two weeks to clear once and some strong-armed...

The mystery is the smoke part. Given the pump uses a rotary arm against the plastic tubing for the pump action, similar to an IV pump, I don't know if it could pump smoke only. The head moves off the capping station a few times on firing up to get some wiper action so any smoke should...

Has anyone replaced just the PK/MK damper valve? This thing: https://www.ebay.com/itm/263749332301?ul_noapp=true The Epson Service Manual shows some shuttle valve pin that pushes back and forth against on the sides of it to switch the inks. Since it is common to both inks, it might be the...

I ended up sending mine in not having the flex-circuit strip. They fixed it for free and sent me a new one along with a case and a ColorChecker mini card. Better deal.

Print head is likely good, but it does sound like the dampers are sludged up. Might be able to backflush them from where they attach to the print head with some plastic tubing like the ones on the top of the print head, silicon hose from a hobby shop, and a syringe. For parts...

I'm unclear as to what you did. You said you did four cleaning cycles to refill. Did any of that hit the capping station and make its way to the maintenance tank? Did you unplug the two cables to the printhead or not? One may not be fully seated if you pulled them off. I use DeOoxit Gold...

ISF, that sounds plausible. The vinyl (PVC?) is very thin so it might be it has no barrier for the adhesive solvent and maybe that affected the surface receptor layer over time. Need to go find some more, maybe an artist's shop as the sign shop stuff is too expensive and only comes in large...

ISF, it was from a sign shop who used pigment inks on it, and it did work a year ago when I used it too. This stuff must change over time, and maybe the plastics in it alter so it will not accept the ink. That's why I asked if it anyone knows if vinyl has an expiration date (They cut it from...

I bought a roll of adhesive=backed white vinyl from a sign shop. 48" wide and not cheap! A year ago I printed on it fine with pigment ink. Yesterday, I tried a small piece and the ink refuses to dry on it even overnight. Still wet this AM and I can wipe it off with my finger. I also tried...

This sounds like what I went through here: https://www.printerknowledge.com/threads/how-to-go-about-flushing-all-ink-out-of-a-3880.12502/ Mine is working fine since then (Whew!). I think it took about 3 power cleanings to flush the line along with the nozzle checks, and I let it sit for a few...

Saw on Luminous Landscape site from a reseller: https://forum.luminous-landscape.com/index.php?topic=126971.msg1071040#new Seems to affect the older models more with a 10% hike, and 5% in new models with regards to ink. So 80ml of 3880 ink might be around $68/cart, or $3,217/gallon. Seems...

The large black plastic one that covers up the rear of the whole printer. Goes around the power cord outlet. All the screws are #2 Phillips. No guarantee you can get deeper into it once that entire back panel is off, but it's an easy-off type of panel to see what is in there. W.F.
