from the printer control panel to clean the printhead.
Never turn off the printer when ink cartridges are not installed. To avoid issues that require cleaning the printhead or that can damage the ink system, always replace ink cartridges as soon as possible, and always turn off the printer using the Power button.
From the printer control panel, open the Setup menu.
Open the Printer Maintenance menu.
If necessary, open the Tools menu, and then touch Clean Printhead.
A test page prints.
Examine the test page.
If the print quality is unacceptable, touch Clean Again to continue the next level of cleaning. If necessary, repeat these steps for the third cleaning cycle.
If the printhead is badly clogged, it might require another cleaning cycle. If so, wait 30 minutes before you perform all three levels of cleaning again.
