mp 510 print head burning

[jimwejimwe]

Greetings

MP 510 burning the blue out of the print head. I was using InkTec ink after I had to reset all cartridges, that refill the blue burnt out. I got a new print head installed didn't last, before the cartridges were empty burnt the blue again. Then I got a new print head and new blue cartridge after it was empty install this time with Image Specialties ink and the blue burnt again. I got another new head and a new blue cartridge the head then lasted until I had to hold the reset button on that blue as it was the only new cartridge. during the next refill the blue burnt again. These heads are no good I have washed extensively under the tape flushed with windex they all print the same funny pattern in the blue. So I back flushed all the cartridges check there flow at least one drip per second with water. I got a new mp 510 machine install these cartridges and after I got all four reset I got about 50 pages blue burnt the same way the same pattern. I checked the cartridge for flow yes when the screw is taken out the ink drips out at about one drop per second. So I have four burnt heads and three different blue cartridges and two machines. Do I smell a rat is Canon shutting us down!

Any help or ideas would be helpful.

To sum up the heads I have Soaked overnight in water, flushed under the tape, flushed and soaked with windex, soaked in ammonia and water.

The cartridges I have back flushed, and check that ink flows through. They print good when first installed.

Tried InkTec and Image Specialties Ink.

Really stupid question but are you burning out the heads when your cartridges are empty or are you getting insufficient flow from your cartridges resulting in the burn out?

Sorry to post Stupid questions.
Purhaps I failed to add the frist head burnt with about 1/4 cyan ink left, I didn't check the flow of the cartridge. 2nd head burnt with 3/4 cyan left and didn't check the flow. 3rd head 1/3 cyan left and did check the flow it was good. 4th head burnt new machine used cartridges freshly back flushed I got about 50pages and about 7/8 cyan ink left, did check the flow and it was good.
I emailed Canon tech support detailing my problem and they told me to take the machines to my nearest service center for them to check them out and find if any warrenty would apply. These machines are 3 months old.

It would help if you would add a little more detail explanation on what steps your are doing. For example in your post you said,

during the next refill the blue burnt again

. You don't really mean it 'Burnt" while your were refilling it. Did you smell it burning??? Did the paper catch on fire???

If you are doing a lot of cleaning and rinsing with water, are you sure you used an air compressor to dry the water out from behind the prinhead circuit board where the eeprom is located? There has got to be some other kind of problem if it is always the Cyan ink. Last of all, what do you mean when you are saying "Burnt". There is no error message about burnt. What are your symptoms of "Burnt"? I expect you will say that it won't print Cyan anymore. That does not mean it is burnt out. I don't think you have anyway to tell if a head is burnt out. There is a diagnostic that will tell you if the printhead has exceeded thermal temperature and that is the service print test which prints out all of the information in the EEprom on the main PC board. Print that out and load a copy to your post. You will have to scan it and save it as an image. If you have really ruined 3 printheads in the Cyan color, I suspect that you've kill the cyan driver on the main PC board, not the printhead.

Canon didn't do this to you,... you did a lot of it by using inktek unversial ink in a new printer that should have ink for CLI-8 and PGI-8 carts. I can see that you tried Image Specialist ink only after the damage had been done. Yes it was a new printhead, but the drivers for the printhead comes from the main logic board. If the EEprom has stored the fact that the Cyan printhead went over temp, it may not print again until it is reset.

I don't think Canon is going to pay anything on warranty because they can see that you have been refilling the ink carts, and their eeprom will tell them exactly how many times you took each cart out, each printhead out, and exactly how many pages you printed of what. When you held the "Resume" button, then refilled the cart, you told them what you were doing. If they sent you 2 replacement printheads, consider yourself lucky. If I were you I would get it to the service tech and pray they fix it under warranty.

If they fix it for you, I would suggest that you learn how to take care of your printer and printhead, and stop using junk ink. Also, make sure you know what you are doing when you clean the printhead. You are probably using tap water and you live someplace where the mineral content and salt content are very high. Those will clog the printhead and combine with the ink to really screw up a printhead. Use distilled water to clean or buy cleaning solution. Go to

How do you know your Cyan was burnt? Was it only stopped printing Cyan? It's not something you can actually see and say yeah it's burnt. How did you determine that it was burnt? I got a feeling that it was only clogged, not burnt.
