If the color of any of the bars is not uniform, follow these steps:
1.If the printer was recently transported at a high altitude, try a printhead cleaning.
2.If the printer was not recently transported, try printing another Print Quality Diagnostic report. This will use less ink than a printhead cleaning, but if it is not effective, try a cleaning.
3.Retry the Print Quality Diagnostic report. If the colors seem to be improving, continue cleaning. If the colors get worse, contact HP - the printhead may need to be replaced.
