My yellow print head on my Epson xp-440 was severely clogged (completely blank print). I tried every other less-invasive procedure I could find but nothing worked. Bought this fluid as a last resort thinking my printer might be toast, but it WORKED! The product came as described (100ml bottle, syringe, gloves, instructions). Felt a little small for the price, but considering it saved me from buying a new printer, it's worth it. It is very important that you follow the instructions and watch some videos for your specific modal of printer before giving it a try. Print heads are very complex and delicate, if you inject with too much force you can burst the print head tubes and permanently damage your printer. And if you drip fluid all over the inside of your printer you could cause a short circuit. You must be extra careful, clean and patient. This is not a 10 minute fix; expect to spend a good weekend on it. Important tips: 1 - If you can, only remove the ink cartridge of the color you need to clean. If you need more space to access, remove all the cartridges, fit the syringe tube over the right color, then put the other ink cartridges back. It takes a long time to inject the fluid (at least it SHOULD if you’re doing it right), during which the other ink nozzles will start drying out if they’re exposed to the air for too long, causing more clogs. This happened to me but it’s not too hard to fix, just have to use some more fluid. 2 - When injecting, use BABY pressure. Even slower than is shown in videos online (where they are usually using brand-new clog-free printers for show). It should almost look like the handle isn’t moving, THAT’s how slow. The nozzle tubes inside the print head are miniscule; if you think about the physics, even a tiny amount of pressure on the syringe handle becomes exponentially more pressure inside those tiny tubes. So have PATIENCE. 3 - I layered a paper towel strip and two strips of watercolor paper (because it’s what I had) as my “blotting paper”. Worked well to catch the mess. 4 - Warm up the fluid per instructions. Makes a big difference. -Finally, this is how I cleaned my print head: Filled the syringe with 4ml of warmed cleaning fluid. Then gently fit it over the yellow ink inlet (the one that was clogged). With BABY pressure, I injected a tiny amount of fluid, just enough to get it into the print head. Then I left it attached like that for about 3 hours total. I came back every half hour and gently worked the syringe handle (pushing and pulling), slowly injecting a little more fluid every time until the whole 4ml were used. I then replaced the blotting paper and repeated the process with about 3ml of fluid. Once finished, I cleaned up the inlet area with a que tip, replaced the ink cartridges and let my printer sit for another few hours before turning it back on and running a test print. It’s important to let your printer sit for some time after cleaning for a couple reasons (1) to let the remaining juice inside the print head do its thing, and (2) to give any possibly missed drips of fluid/ink inside your printer time to dry out before you start running electricity through the machine (precaution to avoid short circuits). After all this, I had to run a cleaning cycle only once for my yellow to show up perfectly! Very happy with my purchase!

I had problems with my Cyan color in the Epson ET-2760 Ecotank printer for several months. After running many printer head cleaning cycles and not solving the problem, I ordered this product. My printer now works perfectly - so pleased. The directions in the kit were well done - follow them! I also watched a youtube video of using a similar product before I disassembled my unit - which gave me greater confidence that I was not damaging anything. I'm not super mechanical, but I was able to easily do each step. Also, be patient and inject the solution slowly and wait the suggested times for allowing the solution to do it's job. You will need about 24 hours to complete the whole process. Plan accordingly since you will not be able to use the printer during that time. Here is how it worked for me: I did two round of the warmed cleaner (one-hour apart). I chose to do the heavy duty cleaning, which suggested waited overnight (or 12 hours) and applied a third round. After reassembling the printer head, I ran a "Power Cleaning" through the printer settings (it's not obvious how to start that mode, as you have to hold down two buttons at the same time, but I found direction specific to my model on youtube for that too). Make sure your ink tank is over half full as a "power cleaning" does use a bit of ink. My model then recommended letting the printer sit for another 12 hours before printing a nozzle check. After running nozzle check - everything now looks perfect!

I got this flush kit for my Epson Workforce all-in-one printer/scanner. The print began streaking one day and the more I tried to fix it, the worse it got until all colors would no longer print anything. So, I gave this kit a try and Bam! I flushed the heads once and got immediate results on all heads. They weren't perfect yet. But, they were at least working again. I tried a few more times, also applying the tips in the manual, like heating the solution and reversing the pressure a few times. Eventually, most all of the streaks went away. I now just have minor streaking and splatter from the black head. I suspect this might be dried ink on the outside of the head, which this kit wasn't designed to address. But, a Q-Tip, a drop of the solution, and a lot of luck at blindly finding the head should do the trick. Update (24 hours later): As for the planned Q-Tip procedure, it was a really tight fit, even for just a Q-Tip. But, it did allow me to find and remove the suspected cluster of dried ink. So, the black-splatter problem appears to be resolved along with less streaking. I still have only 5 black nozzles left to unclog (yeah - so good I can count the bad ones left). About 1.5 dozen yellow nozzles and most of the cyan and magenta nozzles are clogged again. So, it could be something wrong with the capping station (the part that keeps the nozzles from drying out) for the color nozzles. Update (1 week later): I gave the color print-head another two good flushes, with some extra soak-time for the troublesome magenta. Voila! Nearly perfect. The rest will probably work themselves out the more the printer resumes use.

It works as intended. But as it turned out I didn't really need it. OnlyOffice software was causing the problem when it updated to the new version. It will over ride the printer default settings and I thought colors head was all clogged up, since it no longer printed color. I thought it would have more pressure squeezing the fluid through but it went through easily. And it still would not print color. Then I used a different word processor and it printed color. Almost bought a new printer, thinking the head would no longer print color.

It worked! I saved landfill and the cost of a new printer. This was my last hope, and the promise and support offered by the supplier that they guaranteed the product would work, or refunded, is a bold statement. They even provide instructions on how to return the product once you have used it. My HP Officejet Pro 6960 is now printing all colors, so I will keep the rest of the cleaner (plenty left over). Thank you.

My Epson WF-7210 developed a blockage in the print head, and I had tried everything to get it printing again with no luck. I ordered this cleaner as a last ditch effort before I spent way more than I wanted on a new sublimation printer, since there are very few models available currently. The cleaning instructions were quite clear, and it took 2 rounds of cleaning solution to get it completely unblocked, but it is printing beautifully again! I let the solution sit for an hour the first time, but made the possible mistake of replacing the paper towel before it sat for the full hour as I wasn't sure if the liquid would damage the printer if it sat too long. The second time I kept the paper towel underneath and let it soak for an hour and a half and that seemed to do the trick! Best $22 I could have spent!

This cleaner has worked to clear plugged up ink jet heads on my printer. The printer wouldn't print right before using this cleaner. I placed a paper towel under the print head and injected this cleaner into each color head to blast out the dried ink plugging up each injector. It took a couple of tries but it eventually worked to restore operation of my printer, without having to replace the head.

Turns out I didn't need to use this but will keep it for future use.

Works as expected. I do think there should be more solution for the money.
