I tried printing a copy of a printer purge file that had all colors and check which color was having a clog. Two colors had a 100% clog. I tried printing several times with the same result. Then did a light head cleaning (3 minutes) and that did not work. Stoped doing the 7 minute clean up until I tried this product.
I reluctantly purchased it as a last option before I gave up on the printer. Was already looking for new printers. When it arrived, i was ready but my ET-4700 did not readily lifted up to get to the printer heads. You have to remove two little screws right above where the printed page comes out. Then the top part goes up and you have full access to the printer heads.
You have to put something to keep the top of the printer opened. The next step is to put paper towel right under the printer heads. You have to fold the paper very tightly as there is not very much clearance between the printer head and the bottom of the printer. The syringe can eject 5mm at a time. This is good so that you don't flood the bottom of the printer. The bottle comes with 100mm and it is recommended to flow no less than 20mm into each color head with a possible clog.
After the paper towel is in placed between the printer bottom and the printer head, you have to gently take the soft plastic tubes out of the cassette (a little reservoir box where the ink passes right before it prints to the page) that sits right on top of each printer head.
You have a choice to make as to where you plug the tube that comes out of your syringe.
1st Choice: Place the syringe tube on the same place as the soft plastic tubes that flow the ink from the big reservoir.
2nd Choice: Remove the cassette (a little reservoir box where the ink passes right before it prints to the page) that sits right on top of the print head and connect the syringe tube where the cassette makes contact with the print head.
I chose the first one as it seemed the most thorough option. The videos I saw stat that it is almost always right on the head but I though why not clean anything in the cassette as well. Plus the syringe connection to the print head did not all that tight (worried about leaks).
We did 4 flows (as the syringe has 5mm) for each troubled color (we had Yellow and Cyan with a complete clog). I had to be careful when i replaced the plunger after I filled the syringe with the clear fluid that came with the product. The plunger seems to have a very tight seal and I was afraid of shooting the liquid really fast as I replaced the plunger.
After you shoot 10mm of liquid; move the head towards the other side of the paper towel to get that side ready for the other 10mm of clear liquid. If you see the paper towel completely soaked in ink. Then replace it. I recommend using the gloves (plastic bag material) that came with the product of use your own nitrile gloves. The paper towel will be very saturated with a clear solution and remaining ink. Move the head to the left or right and remove the paper towel. Use another paper towel for the next color but if you see too much liquid, clean the printer bottom before moving to the next clogged color.
We only had two colors to do so, we used a few more paper towels to clean the bottom of the printer when we were done. Replaced the soft tubes that go to the cassette (gentle and slow proces) the tubes felt pretty delicate.
We went ahead and did the full printing head clean regardless (7 minutes). You have to turn the printer off and then hold power button + help button for a few seconds to turn on into full cleaning mode. I had full ink on the tanks before I started this process and then seven minutes later I saw that all had gone down, mostly the black ink for some reason.
Test post-product:
Printed the head alignment page and surprise!! I SAW ALL FOUR COLORS in all their glory!
Then printed a personal document and it was perfect.
Very good product and resulted just as intended. Will definitely have this on hand and also use the printer more often from here on.
