Product: HP OfficeJet Pro 7720 Wide Format All-in-One Printer
Operating System: Microsoft Windows 10 (64-bit)

Hi All,

 

How can I perform an ink color test on the 7720 Officejet pro? I think it mixes up my colors. Green comes out as purple licht blue as dark greyish blue, yellow as red, etc.

I thought it was because the cartridges were old and replaced them by new ones but the problem remains.

 

Kind regards,

Yann

You will need to replace the printhead. You have a mixed colours in printhead chambers.
