This consists of two test patterns designed to highlight printhead reliability problems. It helps you to check the performance of the printhead that is currently installed in your printer, and whether it suffers from clogging or alignment problems.
Check the performance of the printhead that is currently installed in your printer, and whether it suffers from clogging or alignment problems.
It takes about two minutes to print the Print Quality Diagnostic Report.
If you have an issue with the diagnostic page, there are steps you can take, depending on the problem.
If the lines in Test Pattern 1 are not straight and connected, align the printhead (see Align the printhead).
If any of the colored blocks in Test Pattern 2 show white lines, or are faded or completely missing, clean the printhead (see Clean the printhead). Follow the front-panel prompts and perform all three levels of cleaning if necessary.
If the problem remains, clean the printhead again.
If the problem remains, replace the ink cartridge (see Replace an ink cartridge) corresponding to the streaked, faded, or missing color block in Test Pattern 2.
If the problem remains, replace the printhead (see Replace the printhead). If the printhead is still in warranty, contact HP Support (see Contact HP Support).
