Welcome to Caps On Fire / Cosmos Ink. First off, I want to say thank you for showing interest in our "Sublimation Ink Conversion Kit." I highly appreciate it and would like to express my gratitude.  

So........you've been doing your research and have came to realize that using refillable cartridges will save a TON of money on ink. This is ABSOLUTELY TRUE!! OEM "original equipment manufacturer" cartridges can get VERY costly due one time use. So instead of spending $45-$50 each time your cartridges run empty, you would simply buy a refillable cartridge and only buy the individual bottles of ink when needed. So whether its sublimation ink, pigment ink, dye ink, or food coloring, you can use our refillable cartridges providing your printer is compatible with our cartridges. For compatibility with these cartridges, please see our compatibility chart below.

These cartridges are ONLY COMPATIBLE WITH THE FOLLOWING PRINTERS:

•Epson WF-7710

•Epson WF-7720

 Epson WF-7610

 Epson WF-7620

Great products

products are great, I do wish they would offer different shipping, i do not like USPS I ship the same distance for my company and it takes 2 days with fedex, it took USPS 7 days from when it was dropped off to them.

Great When They Work

I have been using these for a cartridges for just about a month now. When they work, they are great.

However, a lot of the time the printer will not recognize one or or more of the cartridges. I will have to pull all of the cartridges out and install them again multiple times to get them to start working again. This can be very frustrating when you're doing a large amount of printing.

I did not have these problems with the refillable cartridges I got from amazon, but figured since I was using Cosmos Ink and loving it I would use their cartridges also. I will probably switch back to the ones I got on amazon.

WF-7710 Easy Peasy

These cartridges were simple plug and play and work like a charm. Refilling them is easy and they don't require resetting. Simply pull them when the printer says their low, refill, plug back in and it reads like a new cartridge. Easy day all day.

Time.

Why did it take 6 weeks?? I ordered in for my ET several weeks later and I still received it before my original order for empty cartridges. I no longer need them. In my frustration. I ordered an Epson ET 4700.

I'd say these are hit and miss

Bought the refillable cartridges for a wf7710. Since the day I installed them I've had to mess with them, jiggle them around, or remove and install a couple times to get the printer to read them or whatever but now I can't get them to work at all. When they work, they work great though!

Cartilage issues

This cartilage is not taking the refillable ink, plus this cartilage is totally different than what’s in your video
