Hi, I'm Nathan.Sorry to hear that you're having trouble with this but I'll do my best to help you.
I just want to confirm that the latest yellow cartridge you put in was indeed a genuine canon one, and not a generic/refilled type?
Are you able to pry the current yellow cartridge out?
Yes I'm here, sorry the multiple messages can get lost/delayed.
Thank you for confirming,
we will need to get the cartridge out, it could be in upside down or a defective cartridge.
It will need to come out, so go ahead and try grasping it with needle nose pliers or a tweezers and give it a pull.
Great, now do you have another new yellow, or perhaps one of the old ones, that you can replace it with?
Lets put that in, but first take a peek in the ink slot to make sure there is no debris in there.
Any errors after putting it in?
Do you see anything physically wrong with the new yellow cartridge? Scratches, bits of plastic protruding, etc?
Do the other cartridges insert/remove freely?
Yes take it out once more to see if it moves.
Okay do you have one to put in?
It is sounding like there is a physical defect in the yellow slot.
The cartridges are the same physical size, the difference is in the capacity, one is regular and the other is an extra capacity, so just has more ink inside it
Does it sound like a grinding, clicking, or squealing sound?
Okay those are relatively normal, it is the purge pump,
does the print quality look ok?
Okay the issue is hopefully resolved then if you are getting acceptable print quality and no further errors. It is possible there is some damage or obstruction to the head, but there was likely just something in there to begin with that caused the yellow to not work quite right.
