MX922 color adjustments using iPad and AirPrint

[Amznwmn]

My printer colors were fine until I had to change empty cartridges. Now, my blue is a sickly, faded robins egg blue. I know there's a way to fix this using my iPad because it happened before quite a while ago but I, obviously, don't remember how to fix it and I, unfortunately, didn't write down the solution (but will this time!). I seem to remember something about cleaning the rollers manually, but mentally I can't connect dirty rollers with bad color.

 I have looked on every menu and tried every adjustments but still keep printing this ugly blue. Any suggestions would be greatly appreciated!

Thank you in advance!

Is the printer also connected to a PC or laptop?

Did you run a nozzle check to be sure all is OK?

Check that all the tape is removed from the cartridges.
