GX7020 Color are not printing anymore, even after nozzle cleaning

[zingertech]

Hello,

I have a GX7020 printer. All of a sudden my colors were fading and now completely gone. Only the black color prints.

I have a half tank left on all colors and I have gone throught nozzle cleaning procedures, even the Deep one.

What else can I do to get the colors to print again.

Let me know ASAP! Thank you,
Robert

TechnologyIssue, thank you for this! The manual was absolutely useless, resulting in unneeded purchase$ and a useless $ervice call. You solved it with two words: Ink Flush.

Nope, I still can’t get colors to print. This has been the worst printer experience and it was more expensive and similar models from other brands. I’m dumping mine and getting an HP or Epson.

Its not called INK FLUSH in the GX2020, its called head ink replacement in the gx2020, this sorta worked, still have some streaking and the colors are still sorta fadded. 
now it takes a BUTT load of ink to do this.. and will kill your maintenance cartridge, so make sure you have full tanks. my yellow and blue went from full to  under half. while the red went to about half. so expect a crap ton of ink to disappear, but it did somewhat fix the no color print issue to at least some color.
