#1 Refilled Canon Printhead Failure: it is NOT clogged!

If ink has dried within the head, using force or high temp will only make it harder to remove and ultrasonic and suction won't work. You want to start with the physically gentlest method . Start with low temperature chemical solvent and soaking, alternating with rinsing with warm water in a gentle flow in BOTH directions until the water runs clear. Check that head is clear of ink when resting screen side down on a dampened towel for 15 minutes. If any color emerges do another cycle.

hi, my nozzel check looks great on the colors and BK except for the left part (bars with C, C, M, M, Y, Y, between them) Those are all printing as a dark green. So my photos are all tinted green. But the black and color patterns seem to be perfect... What can I do?

What does thise 3301-3350 number mean?

Explain the numbers below what do they symbolize ?

The number below the lines does it symbolize number of pages you can print with the ink inside the cartridge?

Thank you very much Kevin!! 👍 I was close to buying a new head for my ix6810, but your video save my day 😁. Greetings from Brazil!😉

Seems like the ink channels are all flowing after all those different cleaning methods, but maybe something electrical? As the 100% Cyan isn't firing 100% at all... but does for the Cyan 70%-80% test bar?

All my CMY (and dye black) are NOT firing... but my pigment blacK does. The ink flows though manually, just not when printer executes the nozzles.

I refilled my canon pixma e 3370 then later i took a nozzle check print then yellow color is not coming in it please brother help me

Great video. What does it mean if the entire top section with the black grid lines does not print at all?

It’s not fuzzy, or slightly printed, it is completely missing, and the rest of the page prints fine.

Dear Kevin,my Canon Pixma MP490 prints perfect black but does not print color at all.When I print a nozzle check pattern,black is printed perfect,but below it the page is totally white (blank). Not a single trace of color. Both black and color cartridges are full (I refilled them myself). Of course,I've tried all unclogging methods, but nothing worked. Any suggestions? Happy 2023!

When you soak the printer head in water........I sure hope its only distilled water as tap water has too many minerals and will cause issues when its dry,

Thank you so much xxxxx

Hello Kevin BCH. Ihave the first problem and after 6 cleanings it still persists exactly the same. The white streaks in the nozzlecheck is not in the full-color bar but in the 70% bar on all colors blu, magenta and yellow.

Another problem is on color prints, i see a faint bar across the paper, it's not a white streak, that has a slight darker color than the color on paper. It's on all color prints. Could it be a dirty roller or the paper is too close to the printhead at that point?

Thanks

Good day, thank you for this info. but it doesnt work for me. i did all the cleaning, deap cleaning, hot water, vacuum, but still the colored cartridge still not working. but when i check the nozzle, i put it on a tissue paper theres a mark of the 3 colors. but when i put it back in the printer theres no coming out. what should i do sir?

Could another possible reason be that the gold pad contact for that specific nozzle is not cunducting properly?

I had a black canon cart do it, then replaced and then the color did it, been trying everything it prints just like that

hi Kevin at BCH I like the information you provide in this channel. I would like to add a bit why there are 2 lines of check nozzles in each color on a canon printhead. Although in some types there are several colors that only display one line. From my observations why there are 2 lines of check nozzles in each color is because there are 2 lines of nozzles in each color and both have different hole sizes. One row has a larger hole diameter than the other (in certain types, 5pl and 1pl are listed). That's why we get 2 lines of check nozzles. However, in some types, we only find 1 line of check nozzles, possibly because the color has the same nozzle diameter size each side.

Where can I buy these cartridges or what kind of cartridges are these? I have a g4411 and the black needs to be replaced.

do you know any suppliers of empty, refillable cartridges of this type?

what does it mean if the grid lines have a double lining in the middle, and the "PGBK" word on the left of the grid is also doubled when I do this nozzle check?

I follow your clip, but the position of black bar "BK" is sitll zigzag. How to resolve it?

Hi Kevin. Thank you for the informative video. Just one question. I have a Canon ip7240. On the nozzle check print, none of the Cyan lines are printing. It comes out pure white (as per your video). Is it safe to assume that the print head has died?

My magenta is clogged. I soaked the cartridge in the warm cleaning solution then used the priming clip. In the nozzle check, there are now bars for the (supposed) magenta, but it is orange, same for the yellow. Will the magenta eventually come out?

Okay so what do I do when my nozzle isn’t clogged but my pics still print out green

Mine only print blue… unclog it except one nozzle really doesn’t come out the ink from the bottom . Do I need to replaced print head?

Привет. Можно сделать субтитры к этому видео? Очень интересно узнать, что значит в тестовой странице светлые полосы каждого цвета. С чёрным цветом всё понятно, каждый пиксель рисует свою часть решетки. А цветные заливают полностью полигон. Почему так? У Epson цветные картриджи рисуют решетку.

Thanks for this video... the issue broth me here is a bit different. Hope I can hear your suggestion.
My original printhead showed double lines on the squares at the top - so I ordered a new printhead
But, the new printhead is not printing anything below the graph with the squares at the top. Not even the black marks on the side. In other words my printer doesn't print anything color so far. A rainbow text will end up as a blank page, even if the printer is acting as printing, the paper has no color ink on it. But everything black comes out nice and sharp.

Is the problem with my printer or my printhead?

had same issue with my cl811 worked for few months then got issues like this.i even took everything apart. can it happen that its an issue from the back? copper contact from cartridge to the printer? was planning to revive my printer on getting a brand new cartridge :)

Mine , when printing it fades or its light like so light that it doesnt match the original color how do u fix that please can someone answer???

i print red but orange print appeared? what is the problem?

I'm a software engineer. I used to hack printer devices (for example the epson xp320). In their program, there is a hard limit on how much ink can be spent on each color on one cartridge. What it means is even the nozzle is not clogged/jammed, the program will still disable the ink cartridge via its chip and makes it look like the nozzle is end of its life after certain prints using that color. That is the main reason of refilling ink doesn't work that well. I verified it by changing the chip on that cartridge, and everything just worked again. Not only that, the printer body will have a hard limit on how many times you can use the internal program to clean the nozzle. After that the whole printer will just stop working if the limit is reached.

Im confused, you didnt fix it tho? So how to?

FINALLY! An explanation/demonstration of what these printouts mean! THANK YOU!

hi! wich liquid did you use for the vacuum process? I have one with edible ink! Thank you so much

pro!

Say the end part, it in the beginning. 😄 Save us time to watch it.

Canon MP520 ITs been a great printer. But the print head failed... or so I thought. I bought a new print head and at the 1st the printer did not recognize it. Then it did. Printing was restored slowly but there is no yellow. So I tested the print head in a different MP 520 = all colours have perfect saturation in the 2nd printer. So the yellow does not work in the first printer. Checked and cleaned gold pins on carriage with iso propyl = no change! Any suggestions? Eeprom, connection?

Hello there , please help
I tried to unclog the canon 47 black cartridge by putting it into hot water for 10 min and dried it, but in the end I'm unable to succeed it....there is problem of horizontal lines on taking prints ...,
What should I do... please help

Hi kevin. My coloured cartridge pg 746 for canon is not printing cyan. I have tried everything from priming to washing sponges and putting it in warm water or steaming it or putting pressure. Please help.

what's the problem if those "CMY" black part becomes brown?

i inform everyone with this kind of problems, that canon is being abosive trying to sell his printer ink with the following method ..., because i already had two high resolution printers of the same brand a mark ii that gave head problem because I used cheap ink cartridges when I wanted to use them just for copying so I stupidly bought a pro 10-sa to think that I would never have any problems but I was wrong, I need these companies for photography exhibitions of which I use the originals but how the ink is it is very expensive for more basic things I change the ink cartridges, only that both had false problems in the print head. whenever I used non-figdinios ink cartridges from the beginning it diminished the quality of purpose after it gave the print head a problem with some use or injected a few more colors, so I decided to do some tests I changed for all the figdine ink cartridges and she magically stopped giving problems, then not happy i decided on 2 or 3 white ink cartridges and it worked well on the table. again I added more altered cartridges and it was a problem after a few prints. So I decided to understand what was going on and trick the system to see if it was really ink or canon to sell your ink cartridges created a purposeful problem. and voila I drained all the original ink from the fiddinios ink cartridges and injected the ink of another brand for testing, so I printed many things and it was no problem, that is, the problem is not the ink but the canon, they do something to give problems on purpose. ... it was my conclusion I spent a lot of stress with this problem I think I am not obliged to always have to use the brand's ink ....

may be it is a contact point problem. i have this problem too with my catrigde may be you can try

you did not try the suction you can buy online suction for specific cartridge

And finally Method 6: Sledgehammer

I did a nozzle check but it's blank where my cyan should be. Can you help?

Sir whats the problem if I print there line in the picture?

I did a nozzle check and there are no magenta stripes although all ink wells are full. Can you suggest a solution?

Thank you for this video! My problem is that the black is not printing at all and the black ink just oozes or scatters in the printhead? How do I resolved it. Thank you so much in advance for your response.
