Printers Jack Printhead Cleaner for Inkjet Printers Brother HP Canon Lexmark Officejet 8600 5520 4620 6520 6600 6700 6968 6978 8610, MX922 922 Pro 100, Cleaning Kit Solution 100ml / 3.4oz

Have a Canon MG6320 and we just don't print often enough. So it happens quite often that the print head dries up and I have to clean it. Most of the times, the print head will free up after running the internal cleaning process a few times. This time, however, was much worse. I tried using some household stuff and even took out the entire print head - only to see that there is no way to remove a clog that's inside the head. Replacing the head is expensive and china parts will take a month to get here. So I gave this stuff a chance and it worked super quick. It cleared the clog with first procedure. Just notice that the print head stores a bit of ink in it so it takes a few prints to fill up the ports with ink before you can actually print again. It will throw out some blank pages but after a little while everything is back to normal. It's quite a mess, so if you can remove the print head and do this on a plate or so - I would highly recommend doing so

Followed the instructions to the letter, first try did little to fix the problem. After several repeats, got the problem fairly well resolved, but still have some spotty pint areas.

My really nice HP printer I’ve had for 3 years was printing lines and not printing the cyan color. So I watched a few YouTube videos on how to fix my HP office jet 6500 printer. I have tried everything with the printer as far as cleaning the heads and running the report and the alignment again. But the cyan was clogged. So I tried this kit. It did clear the black yellow and magenta just fine. Unfortunately it would not clear the stuck cyan. I think the key would be to do it once a year. I make a lot of copies and I didn’t think to clean the inkjets. But now I know! So I ended up buying another HP OfficeJet 8000 model. Too bad because this printer still printed black copies. I think this is a good product I think I should’ve just cleaned my printer sooner.

I bought this professional HP print head cleaning solution to clean my printhead after the black color is clogged. At first I tried all the suggestions from HP customer service, didn’t work. I was facing if replace my HP Officejet 8600 with a new printer, it will take about $100. A little expensive for me, So I would like to find some cheaper solution online, this cleaner only $11.98! I have nothing to lose, then I place the order. According to the guideline of the seller, I took out the cartridges and move the carriage to side, took out the paper towel and blotted and blotted the area below the printhead, inject 1ml printhead cleaning solution into the inklet of black color,wait about 1 hours. Then put everything back in place. Try to print a test page, and found that the black color is more seriously blocked. I was so upset with the cleaner and went to search online for a new replacement printer. At the same time I was searching, I received an email from the seller Printers Jack saying that hadn’t heard from me so they want to offer assistance if I need help and offer to refund purchase if they and their solution didn’t solve my problem. I think I have nothing to lose, so respond my situation for more help(without much hope). However, after their quickly analysis adjust the reason is most probably because the cleaning liquid hasn’t been totally discharged and still stays inside the print head. Under their guidance, I draw 4 ML black refill ink with a syringe and inject it into the ink port of the print head, then install the cartridge and run the driver's "Print head cleaning" function. Then I restart the printer, OMG my HP 8600 is working now as a new printer! After above experiences, I am so pleased with this purchasing. The customer service is so care about their customers, and real people to provide support for your printhead cleaning problems.

Spent several hours on this: From watching “how to” vids to reading how to docs to actually trying it. Before the printer would print and perform normally with the exception of the correct color print. This HP 8620 sat in a part time home, very little use, which I am sure lead to the print head clogging up. After using this product, burning so much time, it is much worse now. Glad others appeared to have success with it, not me. By the way, I use Mac OS, Windows and Linux. My first computer had Windows 311, have built several computers, repaired several, not new to this sort of thing... Update Edit: To their credit, the company that I purchased this product from through Amazon has reached out to offer me a refund. I purchased a new printed quite a while back that came with full ink cartridges and all is well. While this was a more expensive solution, it was the most direct/effective resolution. I will say, upon reflection, if you have lots of spare time to dedicate to this, by all means try this product. Make sure you do a significant amount of research before attempting. Or solicit the help of a friend who has done this sort of thing with printheads many times before and finds it easy due to experience. But if you’re anything like me, putting in many hours six days a week, my time is better spent on other endeavors.

The product came very well packaged and with different sized nozzles to use on different brands of printers. The flushing went very well. For my HP Inkjet, the hose fit just fine. I followed directions and inject the cleaner slowly. I purchased this on the off chance that my issue was with the ink and not the print head, as the error message told me, but turns out it is actually the print head. So I can't comment on the after use print quality but I am keeping the remaining fluid in case my old unopened inks turn out to be bad and the device needs flushing. Still a win in my opinion.

Will not unclog really dried out or clogged heads, Not strong enough to dissolve/clean these types of clogs. Make sure you clean up any spills, as liquid tends to gel and make a mess if left on a surface for a extended period

I used some non original ink in my HP 8600 printer which caused some lines and colour issues that couldn’t be fixed by using the printers printhead cleaning function. I was looking at a new printhead but decided to give this cleaning kit a go as I had nothing to lose but I admit I was a bit sceptical about it working. I removed the printhead and followed the instructions to let the solution soak in the affected tanks for an hour or so then reflushed with the solution. It’s a messy process so do it over a sink. I loaded up the ink containers and reinstalled the printhead and ran the cleaning program again. To my amazement and relief everything was perfect again with no lines or faded colour. The kit was easy to use and has ample fluid to do this many times over. Fantastic results which saved me $$$
