My 6-month young Pro+100 died on me today. No Yellow!

You’re not over filling your carts by any chance or allowing your carts to go beyond low ink before refilling, because this issue can masquerade itself just like nozzle clogs, and don’t remove the print head anymore, because that’s not your problem right now.

When you have a good and proper nozzle check once more try printing this test sheet, this will show up any ink flow issues with any of your cartridges...

Dearest Hat,
Have just returned from holiday and after letting Print Head rest in shallow ''Pharmacist's Solution" for a week I am happy to announce that a new Nozzle Check has once again showed Yellow.

So I will hold off doing anything until instructed by you how I should proceed. Exactly how do you want me to print the Color Chart. It is of low-res, shouldn't matter, right? On gloss paper? Full A4? Any other advice? Thank you @The Hat

OK Sir, printed. Here it is, plain paper, cropped.

I would say looking at the test print, that your good to go.
Happy Printing...

Thank you, that's reassuring, but for how long I wonder? Once bitten, twice shy... in this case 3 or 4 times bitten already. Will give it a go (still recovering for our holiday, no not hungover , just long walks in the countryside . 2,000 photos taken with the Nikon, 1,000 with phone camera. Post-processing alone will take some time)

When I manage to save up some pennies I will invest in a new (spare) Print Head.

This is definitely a cartridge problem. Insufficient ink flow. Nothing to do with your print head!
