Epson et-2769 Black lines in yellow color prints

[simransabharwal]

My Epson ET-2760 pints perfectly but has issues with yellow color prints. There are black lines in yellow color prints.
I have tried nozzle clean, head clean and alignment but the issue was not resolved.

any suggestions to fix this issue will be appreciated. attaching images that show the issue

Please print and post a nozzle check, it could be cross contamination from an adjacent ink channel in the printhead, this should show up clearly there.

Thanks for responding. I am attaching more images.

I don't see another color in the yellow nozzle check, and not in the other sections either. I'm not really clear about the cause at this time. Are you using Epson OEM inks ? How does the problem look with other driver settings - another paper - another quality setting ?

i am using OEM inks but the printer was unused for 4-5 months as I was away. Do you think doing a power clean would help? Even I am unsure what's causing only the yellow color to have this problem. I will try to change the paper and try again.

I had opened the cartridges and realized that the hinges which are made of plastic (that hold the cartridge to the head) of Black and yellow were not as strong as cyan and magenta. I added some paper to force them down and it worked. I dont see any lines. Epson has to improve the quality of their products.

Thanks for your feedback, your fix is interesting; Ecotank printers with a printhead like yours are quite popular, I could imagine that your fix could be of interest to other users with a similar problem whenever. Could you please just make a photo shot of the printhead carriage and how you fixed it.
