Printer 6978 not printing cyan

[texduff]

Printer 6978 not printing cyan, have done the print head cleaning several times.  replaced the cartridge twice.  1st time as the level was low but not a warning.  2nd time since the one wasn't printing blue Staples said they would replace it incase it was a problem with the cartridge.  But still having problems.  We bought this one 3 years ago which replaced a HP - Photosmart 5520 Wireless All-In-One Printer that we had bought 3 years before that.  Does not seem right that a personal printer should only last 3 years.  If we can't get this issue resolved we most likely will not buy another HP.  And most likely not buy another HP computer either as after slightly over a year after owning our current computer the touch screen stopped working and essentially was told there was nothing that could be done as it was out of warranty.  Not a happy HP owner.

Amazing, I had just about the same problem and similar timing as texduff - when I saw that message first I wondered if I had written it (but details were different, texduff was getting cartirdiges from Staples, I was getting cartridges from Instant Ink program).  

In December 2019, the cyan stopped printing in my 6978 Inkjet printer all-in-one.  I thought the cartridge just hadn't been filled properly. 

Then the replacement was empty just about right away.  Or so I thought.  Or maybe 2 defective cartridges? 

Then the third cyan cartridge wouldn't print at all.  So I thought it must be the printer.  Support said it couldn't be fixed so now I am about to buy a new printer.  But reading the message from texduff, now I am wondering, maybe it really is defective cyan cartridges?  

I don't want to condemn a perfectly good printer to the landfill.  How can I tell if it's bad cartridges (3 in a row!) or broken printer? 

[and yes, I have done the clean printer head procedure multiple times, and also it doesn't matter if I copy from the platten or print from the computer, cyan doesn't print.  magenta and yellow and black are all fine]
