Checking and Cleaning the Print Head

If your printed image shows a color shift or horizontal lines, you should
check the print head to see if any nozzles are clogged or deflected. If
necessary, the printer will automatically run a cleaning cycle to clear the
nozzles.
You can also turn on Auto Nozzle Check from the printer's control panel.
The printer will then check the nozzles before each print job and clean them
if necessary.
