Officejet G55: no yellow in color prints

My Officejet G55 suddenly stopped producing yellow ink.
I'm using a refill set, with good quality ink. I refilled the color
cartridge immediately (all 3 colors), placed back the cartridge and printed
a test page. Still, no yellow. Blue, Red and Black are printed perfectly
well.
I used a q-tip with alcohol to clean the copper contacts both on the
cartridge and inside the printer, but without result.
Printing an alignment page fails, the printer shows an error message on the
display.

Now, my concern is: is there a problem with the cartridge, or with the
printer?
If it's the cartridge, I'll have to buy a new one. But if it's the printer,
buying a new cartridge is a waste.
So, how can I determine what causes the problem?

Almost certainly the cartridge. You could verify this by blotting the nozzles
on a damp tissue - you will probably only see cyan and magenta, no yellow. It
is very unlikely to be an electrical issue with the printer, as this would
require eight different signals to fail but no others.

Another with an aftermarket problem.
