Example of Bad Color Bars

The top black bar is ragged on one end.

If any of the bars are ragged, irregularly streaked, or faded, follow these steps:

1.Make sure the ink cartridges have ink.

2.Remove the cartridge corresponding to the streaked bar and make sure it is properly vented. For more information, see Replace the ink cartridges.

3.Reinstall the cartridge and make sure all the cartridges are properly latched. For more information, see Replace the ink cartridges

4.Clean the printhead. For more information, see Clean the printhead

5.Try another print or reprint the Print Quality Diagnostic report. If the problem still occurs, but cleaning seems to have helped, clean again.

6.If cleaning does not solve the problem, replace the cartridge that corresponds to the ragged bar.

7.If replacing the ink cartridge does not help, contact HP - the printhead may need to be replaced.

Preventing the problem that causes ragged bars on the Print Quality Diagnostic report:

•Avoid leaving opened ink cartridges outside of the printer for an extended period of time.

•Wait until a new cartridge is ready to be installed before removing an old ink cartridge.
