Print Quality Diagnostic Report

When you encounter a printing problem you need to perform a Print diagnostic Image test.

1. Use the same paper type that you were using when you detected a problem. The test patterns are easiest to evaluate on plain white paper.

2. Check that the selected paper type is the same as the paper type loaded into the printer. See .

3. At the printer's front panel, tap , then Image Quality Maintenance > Print diagnostic image.

   Note:

   The report can also be requested from the Embedded Web Server.

It takes about two minutes to print the Print Quality Diagnostic Report.

The following steps provide the complete procedure for this topic.

1. If the lines in Test Pattern 1 are not straight and connected, align the printhead (see Align the printhead).

2. 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.

3. If the problem remains, clean the printhead again.

4. 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.

5. If the problem remains, replace the printhead (see Replace the printhead). If the printhead is still in warranty, contact HP Support (see HP Support Center).
