Hello, Your fix says to go to: Setup menu > tools > Restore factory defaults.
I can't even get to the 'Setup menu' on my HP6520 printer screen. What I have is the Settings icon, which is a wrench, then when I press that I get to a screen that has 'Tools' as an option. Then when I press on Tools, I get another menu none of which say 'Restore factory defaults.' The options are: Estimated ink levels, Print status report,print quality report, and Clean printhead.
