Ink communication error

[Jessica1106]

I have the exact problem with my envy pro 6420.

I went and bought new cartridges from officeworks and same error. I did ALL the fault finding steps. 

I reinstalled my printer fresh and it worked for 2 pages. 

What is going on?

Hi @Jessica1106,

Welcome to the HP Support Community

I'd like to help!

I understand you are facing a cartridge communication error.

Try the single-cartridge mode 

The printer you own can work in single-cartridge mode, wherein the printer will be able to print with one cartridge in the printer. This will help us identify if its a cartridge issue or a printhead issue 

To try single-cartridge mode follow the below steps:

• remove the black ink from the printer, leave the color in and try printing 
• then remove the color ink, insert the black  in and try printing 

Hope this helps! Keep me posted.
