Canon IX6810 distorted Pigment Black prints

[exploradorgt]

Hi, I'm facing this issue with my Canon IX6810, the pigment black is printing distorted, when it comes to lines it's distorted, blurry, and when it comes to images the same effect. I have printed a nozzle test and it shows bent and distorted lines.

Already performed print head cleaning of diff types and methods to no luck. After searching the web found this forum, including one specific thread where users report the same issue with different Canon printer models, but what intrigues me is some of them changed the printhead and the problem persisted, one user reports going back to the old printhead and the problem went away but not for too long.

Any help will be appreciated.

I really love this printer, can't relly on seller services as it already expired, the machine was bought sometime ago, it was a gift and it was used from time to time with great results until 3 weeks ago. I was actually about to buya new print head but the results and reports I'm finding that such thing doesn't solve the issue got me thinking and so I stopped.

Thanks Stephen for the quick reply and the explanation. I will explore the options on the given link. I received this printer as a gift and unfortunately I noticed it's a rare model, very few mentions on the web and it seems only exist in latin america.

Thanks jrhoffman75, unfortunately this is not the case, as it's not an dirty encoder issue. I checked mine, cleaned it anyway, and others report the same, it's consistent. I still have my printer, and despite looking for a printhead replacement, I've had no luck getting one that I can test it's in full working condition prior changing.

Over this time I've grown suspicious on this being a logical board issue and perhaps not the print head, unfortunately these models are rare locally. But sadly, in full detail, it's not an encoder strip issue 😞

I posted this issue on 3 forums, and some important information is missing here. Eventually I could get confirmation from people reporting the same issues on specific Canon printer models, it's something Canon already knows, but no details have been shared about it. So, people in the US were able to get a deal from Canon USA, but us outside the US were told to talk to local representatives, no luck there, sadly.

Some users ordered a new print head online, some report having the same issue after replacing the print head, but they also explain it's impossible to know if such "new" replacements are 100% new and in working condition. Some users report having luck and getting rid of the issue, but appearing after a week or to (with the new print head).

And one user reported not showing any difference, so he went back to his old print head, but then the problem was gone (yes, with the old failing print head), and while he was happy about this, the problem appeared again after a week or two.

And the printing issue only happens with the pigment black, it doesn't affect the other colors. IF it was the encoder strip, it would affect the whole print, all the colors.
