Printhead Hospital cleaning kit for Canon printers - 150ml

Used this to partially clean my printer, not entirely got rid of the problem with fuzzy text. A bit messy in use.

I have not given this product a perfect rating for the reason that it is quite expensive considering the kit is generally made up of off-the-shelf parts. Secondly, the Solution is definitely not enough to clean "30" Print Heads unless you use a couple of drops each time. But from my experience, you will need more than a Syringe or two to get a good thorough clean. So in the end, the kit does it's job well but doesn't last beyond say 3 cleans.Yes, the seller does offer a £10 refund if it doesn't work, but honestly, I'm giving the actual product a rating and not his service.Right, so the most important thing in this kit is not the Print Head Solution itself (as it's just a glorified bottle of Isopropyl Alcohol), but the Green round syringe pieces that fit directly on to the Print Head nozzles (see Product Image).There is actually a specific way to efficiently clean Print Head nozzles. This method is also used in a couple of Third party industrial machines that are designed to flush ink cartridges for refilling later. This kit allows you to use the same flushing method on your Print Head, but sadly it's not emphasised in the instruction manual with which the kit comes with. For most people, the usual method of just using the Solution is sufficient, but I have found better results in using, what I call, the "Flush" or "Pressure Spray Method"To achieve this, two things must be done to the Print Head nozzles;1. They need to be rinsed in clean water, and then soaked in the Print Head Solution for at least one hour.2. The Print Head Nozzles need to be PRESSURE SPRAYED with water to eliminate any internal blocking of clogged ink particles.I will now take you through a proper step-by-step process to flush your Print Head (PH). This will GUARANTEE you a brand spanking new PH.Note: If it doesn't work, it means your PH is just electronically damaged and needs replacing. If you're using a refillable ink kit like me, then it means your cartridges are over filled, or that your ink is cheap quality and unfit for use.SEQUENCE 1 (A) - RECOMMENDEDRemove your PH and securely place the round rubber Nozzle seals in a paper towel, so that they don't fall off and get lost during the cleaning process. If you want, take a picture of the PH with your smart phone so that you know which position to put them back in.SEQUENCE 1 (B) - OBLIGATORY1. Take your PH to the sink. Open the tap on a low-medium setting, and rinse the PH for around 5 minutes until nothing but clear water drops off the nozzles. Just to be on the safe side, hold the PH in such a way so that the electronic part doesn't fall under the running water. Make sure no visible ink is left. After 5 minutes of rinsing, it should look clean.2. Put the PH in a little flat container (Preferably 6-10" diameter)3. Heat the PH Solution or Isopropyl Alcohol (99%). Fill the Syringe with it. Spray it all over the PH nozzles, making sure the solution goes in to the actual nozzles and comes out of the bottom nozzles. You should start to see more ink come out from underneath. If not, recycle the sprayed Solution and keep injecting it all over the nozzles. Now turn the PH upside down, and spray the Solution into the vertical exit holes too.4. Leave the PH soaking inside the solution for around 1 hour. Don't tilt the container to one side. The nozzles need to be soaked in the actual PH solution.5. After 1 hour, quickly re-rinse the PH under the tap. Shouldn't take more than a minute.SEQUENCE 2 (A) - OBLIGATORY!!1. Clean and re-install the round rubber seals on the PH.2. Fill the Syringe with hot but not boiling water. Attach the Green round piece on to the end of the Syringe. Place the Syringe + Green piece on to a nozzle. With the PH in your hands raised above your sink, hold the Green piece down firmly. Make sure it's flat and totally covering the nozzle. Now squeeze the Syringe with PRESSURE so that all of the hot water sprays through the Nozzle and comes out of the other end like a jet stream. This is one of the most important steps in the whole cleaning process!3. Do this successfully and you will see an equally distributed jet stream come out of the exit end of the bottom nozzle. Make sure the jet stream is equally distributed otherwise you have a blocked hole and you must repeat Sequence 1B.4. Pressure spray each Nozzle 3 times until you think they are totally unblocked from the inside.5. Dry it. Place it on a new set of clean paper towels.SEQUENCE 2 (B) - RECOMMENDEDFill the Syringe with more Solution, but this time, instead of spraying it all over the nozzles...you need to inject the Solution drop-by-drop in to the round Nozzle holes. Do not make a mess. Do it in such a way that you start to see the towel get wet from the bottom. This way, you'll know the Solution is cleaning and flowing through the internal ink passages of the Nozzles.Let the PH sit overnight until it's fully dry. No need for any more water. The Solution will just dry over night.TIPS: (i) Do not scrub, rub, or wash the electronic part of the PH (ii) Do not scrub, rub or even touch the round PH nozzles. You may damage the tiny pours. You're only supposed to let water and the Solution seep in to them. (iii) Allow PH to dry completely before placing back in to the Printer.

Bought in an attempt to fix the print head on my aging (7 year old) Canon MP610. Printer used mainly for B&W printing and worked fine in B&W but all the colour jets started to clog up. To begin with a quick maintenance clean worked but later it needed a deep clean to clear the colour heads. Then the built in maintenance routines no longer cleared the colour ink jets on the print head.The product is professionally presented, contains all you need to unblock a print head and is easy to use with clear instructions. You should be aware that not all print heads are salvageable especially if they are getting older but if it is blocked jets causing your issue then this kit IMHO is as good as any and better than most to get the job done and you up and running again. The Print Head Hospital kit comes with a £10 refund guarantee if having used the kit (and followed the instructions) your print head no longer works, a unique selling point.I followed the 'quick clean' method. On checking injecting some cleaning fluid under pressure all the nozzles including the colour appeared to be clear but I wasn't 100% happy with the spray pattern, almost even but not quite. Went into the thorough (troubleshooting) mode and did an overnight clean. When forcing fluid through the nozzles under pressure the next morning all traces of blockage had gone and there was a nice even 'fan' spray coming from each of the 5 nozzles. The nozzles were definitely clear along their entire length. I let the Nozzles dry and re-assembled the printer with good cartridges. Re-initialised the print head and ran two maintenance cleaning routines. Alas no improvement with the colours.Got in touch with The Printhead Hospital looking for a magic bullet but we concluded that there was nothing more to be done and the likelihood was that the print head itself had given up the ghost and it was now time to replace the printer. Andrew at the PHH, without me asking, offered to refund £10 under his guarantee even though his product wasn't deficient in any way. The response time for both by enquiries of the PHH were within an hour and I even received an email from Amazon confirming the refund within 3 hours. This is amazing service of the highest order so thank you Andrew Nightingale (owner of the PHH).As a little post script: Being ever the optimist and never wanting to be beaten I gave it one more whirl only to find that the printer gasped out the infamous U052 error code which has been the subject of a legal class action against Canon in the USA. Canon lost but the class action referred only to the litigious USA The U052 code has nothing to do with cleaning the print head either.

I had lost the yellow section of my Canon Pixma MG 5750 and after searching internet I discovered the print hospital and it’s head cleaning kit. On reading the reviews and seeing that should it not be successful there was the opportunity of a refund I purchased the kit.The kit arrived in good time (considering the present situation) and was put to work the following day. Luckily with the Canon MG5750 the print head is removable which did make it a lot easier to tackle. Following the instructions supplied with the kit, it has taken nearly a week to unblock the yellow section of the print head. I gave the print head two overnight soakings in the supplied fluid, one overnight soaking in isopropyl alcohol (which I already had) and a fourth overnight soaking in the supplied fluid (after each soaking the section was pressure cleaned with the supplied fluid). I then refitted the print head, loaded the ink cartridges, performed a head clean filled by two pattern nozzle prints where my yellow section appears to be completely refreshed.I am very pleased with the outcome (saving me a new print head) however it does take patience to get the right result.
