Mother of all clogs

[Harvey]

A doubt dwells in my mind, when using a syringe and vynil tubing, to get rid of hard clogs, the clog gets worse. Same problem with a QY6-0059, and QY6-0073, the problem arosed in both printhead in magenta channel.- Ink was IS. At first litte mist, second try only few drops drops and foam, and then nothing, nada, niente, rien, nichts!

Something got loose, and ended up blocking the expell of ink. In my adventure and having too much to lose, I removed the filter on top of the inlet port. As I was pushing and drawing the plunger maybe, and just maybe, this filter caught some dirt. No positive results, removed the ceramic plate, looked through the nozzles no visible block.

With ceramic plate removed and water being forced water was flowing better, so less pressure on the plunger was needed, ceramic plate and gasket in ther place, screws well tightened, same problem, then the thing got blocked and no force in this world could unblock it.

For removable Canon print heads id first try removing and soaking as described in numerous posts on here, injecting fluid too fast/hard will/can just damage things more.

I know too much pressure will complicate things. What is strange is that equal pressure was applied to other channels just to see how the fan pattern was, and no problem when nozzle check was printed while the printhead was still functional.

Too much pressure wasn´t the problem, I applied more and more pressure eventually as the clog was getting stubborn.

Is this problem linked to magenta channels frying in the Pro-100? Ink involved here is Image Specialists.

@Harvey you seem to be the most unfortunate guy when it comes to killing your print heads with such regularly, but as to the real reason why this keeps happening is not very clear to you.

Your claims that the I.S. magenta is causing all of you troubles seem very far-fetched because worldwide thousands of refillers are using this same ink and have experienced very few problems with it.

Yes there have been some reports of print head damage but they are very few in number and losing the odd print head is not that big of a deal when you consider the saving that were made when using this 3rd party ink.

To have the same problem on several printer is most unusual but did you not think that it just could be your cartridges and the way you were refilling them that might be causing you all of your problems instead of the ink ?

95% of all poor or non-existent ink flow problems are down to the cartridge and not the print head, this is the one area that you have never even considered despite experiencing the same issues on several of your printers..

@The Hat it is certain that I am not an experienced refiller. My refiller approach was back in 2008, my only refilling method was, and will be the german one My very first refills were made with 20ml Inktec which lasted 3 refills, then followed by Hobbicolors like 4 years, cartridges involved were CLI-8.These carts are, at least for me, the most refiller friendly carts since late 2012 I switched to IS ink. When I refill the CLI-221 the same can´t be said, these need more care in order to overfill, which leads to bleeding.

Regarding my claim with magentas is clear, this is the only color which is affected with this uber clog (now that I remember cyan seemed it had a little tendency have ink flow problem, resulting in streaks in cyan areas, but a light/deep clean solved that), dont know why, but this is what I get, and something had to be said. I can´t conceal the situation. I just wanted to let other what I was experiencing, and it is worth that others know. An issue is an issue here, and anywhere in the unviverse. I can´t name it differently, a synonim is a soft way to describe the same monster with kind words. Also in my country we have a saying: "It´s the same the same monkey, but in another tree".

I do understand the rules when switching from OEM to 3rd party, it is not, and will not be the same ever. Yeah, it is also clear to everyone that the savings inherited by using 3rd party inks are big enough the cover a defunct printhead, and the savings are big when take into account that OEM ink is the more expensive liquid in the world, even blood is free, and you die without it. But, and only but, not just the printhead is affected, when you try to tame the beast, and the printhead dies, well that is another story.

Answering your very logic question, which I also asked to myself, is this an ink flow issue? Well no, different carts were used, even virgin ones and different printers, the problem resides in the ink, period!​

Can you let us know how old the ink is? We need information to try and piece this puzzle together. This will help the manufacturer better understand the clues to the problem you are experiencing.

Mike, this ink was purchased from you on December 9th, 2013.

 

[mikling]

Thank You. It is now around one year old +. This ink was made in Holtsville N.Y. and not Boca Raton Florida. Production was moved to Boca Raton in the early summer 2014. These snippets of information is important to help the tech people trace the problem down. They will need to know if location of production is a factor or not. Detective work is now required to figure the puzzle out.

To exemplify the issue of how mysterious it is. I have been using the same magenta in my iP3300 during the same period in the last year and did not experience any problems. However, in looking back, I usually take some ink from whatever comes in the door as I don't keep the same bottle on hand. As a result, I always end up with the newest ink in my printer as I take some as inventory moves in. The situation is then that I possibly consumed the same lot as yourself within a short period of time. This is what makes it difficult for the manufacturer to peer into the problem. They do not keep a large quantity of old ink on hand to refer back to. They keep records of how the ink tested after production. If required, I will ask that some of your remaining ink be shipped to them if they are unable to find problems in the samples of older ink I had scour around to find and send down to them.
Now if the ink was bad from the get go, I would have had issues myself on my iP3300 right off. This is what leads me to believe that the ink is somehow breaking down sooner than it should be. Keep in mind sample sizes are small and incorrect conclusions are easily made at this point.

Not to discredit the original poster but if it was a serious issue with a batch of ink @mikling im sure there would had been a lot more people of here screaming their printer has died If i had to guess id guess more along the lines of @The Hat that it is likely an ink flow issue with the refill of the carts which has led to head damage. (maybe a foamed cart or similar as your prior video guides have explained about).
