# Checking the Print Head Nozzles

> Using the Nozzle Check utility
> Using the control panel buttons

If you find that the printout is unexpectedly faint or that dots are missing, you may be able to identify the problem by checking the print head nozzles.

You can check the print head nozzles from your computer using the Nozzle Check utility in the printer software or from the printer itself by using the printer's control panel buttons.
