QUTHZZHYSublimation 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)

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.

Great

Received product today and the printer recognized all colors but black. Tried every troubleshooting tips to fix. The printer has previously read other cartridges except this item. Reviews are all expressing similar issues.

I know why a lot of people have issues with these and I do have to say these would be 4-5 stars if the manufacturer had a clear video or instructions on how to fill these correctly, if not done correctly they will never print. For those who want to give them a try I can tell you there are a few videos that are related to similar products on YT on how to get these types of cartridges filled correctly but it is never fun hunting them down.

This replacement cartridge works. It was easy to install fit right in like the original. It was all worth the price.
