Sublimation Ink Refill Bottles for WF-7720 WF-7710 WF-7620 WF-7610 WF-7210 WF-7110 WF-3620 WF-3640 Sublimation Ink Cartridges 4 Pack (Black, Yellow, Cyan, Magenta)

Worked perfectly no issues. Printer told me they were not Epson, but then let me bypass.There is Printer setting you can use to not check ink amount and it shuts off the cartridge verification so you don’t see it anymore

First set I purchased, the front attachment containing the microchips would fall off of a few of the colors and all of them would not be recognized by my printer. A replacement was sent. Unfortunately, those were not recognized either (we tried all the tricks we could find off the internet to get it to work). I made the mistake of purchasing a third set, but they were still not recognized. I purchased a set from an entirely different seller not on Amazon and I haven't had a problem with the printer recognizing them since.

Amazing customer support, quick response from seller to help troubleshoot. I reached out because the printer was not accepting the black cartridges. I first tried replacing them, but the issue persisted. After it was said and done, the issue was resolved with purchasing updated “chipless firmware” and installing it onto the printer.

EXACTLY AS DESCRIBED

I'm disappointed, the black cartridge would not register with the printer.

I received the first set, only one of which worked. I probably should have just returned them and been done with it, but I ordered a replacement. They've worked sporadically, sometimes having to take one out and put it back in to get it working again. Randomly, today the Magenta and Yellow are not recognized. I have taken them out and back in over 10 times each. It's really just not worth the hassle. I've used refillable cartridges in the past and never had issues. These are not worth the effort it takes.

My WF 7710, which I use for sublimation, never printed perfectly and got worse over time. I thought it was the print head, so I cleaned it and ended up replacing it. Still, it didn't work well. I then purchased these cartridges, and the printer now works better than ever. No more banding! These cartridges are way better than the ones I got when I originally converted the printer. Don't forget to properly prime the cartridges and not just fill and forget. Videos online on how to do it properly.

Use USB only...helps do not print wireless and they will read
