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.

Interesting. You might be able to pull it out if you take off the black plastic back cover. Can't recall what was under there as it's been a while, but that part is easy to get off with maybe 5 screws (One in the middle was different as I recall.). W.F.

Once you finish all their lessons, you need to spend at least $500 for new ink carts to print out your MPS diploma. :barnie W.F.

Epson has a printer info channel on Youtube called "Epson Print Academy:" https://www.youtube.com/channel/UCJGBlcEqdmSJUK17V8iqY3A/videos W.F.

Bad luck! You might be right that the stiff paper jammed one of those presser feet and the head pushed the paper into it and broke a hinge or dowel pin. Plastic bits in the thing ain't a good sign, nor are loose springs. I fed some stiff stuff once before the plastic printer carriage broke...

I played around a bit with the newer xrite i1Studio software and its new B&W profiling. Took three test pages just for B&W now, but it seemed to do a lot better in producing a neutral B&W image with the 3rd page being mostly B&W test patches and some rows with color added to null out any tint...

ISF, I think I might try the Precision Colors HDR Black next. Wonder if it is the same as the Cone HD Photo Black that they recently came out with - although I think it is pigment. Fwiw, I have a lot of old QTR K7 era profiles that I could flush out. That was a huge waste of time and money...
