PIXMA GX6021 not printing any color at all

[GrandmaD]

My nozzle check test page prints only black.  I have done the cleaning and the deep cleaning multiple times.  I replaced the maintenance cartridge today, did another deep cleaning and ran the ink flush.  Still only prints black.  All three color ink tubes are approximately three quarters full.  I am using a laptop with Windows 11 and using a wireless connection to my printer.  Help?

Did color ink flush, did any color show up in the nozzle check?

Quick checklist — try in this order

1. Check color ink levels

   • Open printer software or control panel and confirm cyan/magenta/yellow cartridges have ink and are recognized.

2. Run deep/nozzle check & head cleaning

   • Print a nozzle check pattern.
   • If missing colors, run a deep/extended head cleaning cycle (not just a quick clean). Wait 10–15 minutes between cycles.

3. Power cycle and reseat cartridges

   • Turn printer off, unplug 1 minute, plug in and power on.
   • Remove each color cartridge, inspect for protective tape/seals, then firmly reseat.

4. Check for clogged/airlocked lines after flush

   • If you flushed manually, air or solvent may have entered lines. Run several cleaning cycles and leave 
   • the printer powered on overnight to allow ink to re-prime.
   • Avoid further manual flushing unless you have a full set of fresh cartridges and know how to purge air.

Thanks for the response.

1. My printer does not have cartridges - it has ink tanks.  They are all showing as at least 3/4 full.  

2. My print nozzle check shows only black - no colors at all.  I have run the standard cleaning as well as the deep cleaning.  Waited 24 hours and ran the deep cleaning again.  Still no color printing on the nozzle check.

3.  I have turned the printer off and back on multiple times.  I have unplugged the printer as well.  Again, my printer does not have cartridges, so cannot remove them.

4. I did the ink flush from the maintenance screen yesterday.  Still no color printing on the nozzle check pattern - just black.
