Brand new Cartridge - Cyan not working

[CazOz]

Old colour cartridge was running low - cyan was not working - thought it was because of low cartridge

Replaced with brand new cartridge, cyan not printing, ran diagnostic, said clean head, did that, still no cyan, have cleaned 5 times now, no cyan printing. Yellow and magenta ok. 

Cleaned print heads twice more for good measure still no cyan printing - really cranky now!

Any suggestions other than throw away anything HP

Thanks Prem_M but I have tried EVERY single thing in the information you sent me.

I've cleaned more than 10 times, I've re aligned, I've reinstalled, I've manually wiped, I've turn on and off, I've reset

The cartridges are genuine HP.

I've tried several brand new genuine cartridges and each time same thing - Cyan does not print.

It is only Cyan the other colours work perfectly - how can this be ??

Need a solution.

Greetings and noted your input.

Because it is only Cyan, it could be related to the electrical contacts. I am hoping you have cleaned the contacts as well.

if the issue persists, you may need to get the unit serviced by an authorized service center.
