Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
It sounds like an alarming sort of difficulty; I hope I can help with it by advising you.
But I need to ask a few questions about the details, please:
- How old is your printer?
- Have you been using Epson OEM-original inks in it?
or, have you been using 'compatible' cartridges in it, or refills, or remanufactured cartridges, etc. ?
You could try to replace the yellow cartridge, and also check the place (or, slot) that it slides into, to see if you can see any obvious defect.
But I fear the printer is 10 years old, and a part of its inking system may have simply worn out with time usage and age.
Replacing the yellow, printing about 5 more sheets including the yellow color some, and seeing if the problem persists, would by and large prove this (one way, or the other.)
When you try what I recommended yesterday, please take the time to let me know how it goes and what you found out. Thanks.
