Align Printheads
Align printheads performs a maintenance function with the printheads. Proper alignment insures correct registration between ink colors while printing. This is only recommended if you are experiencing problems with print quality.
Before you continue, please verify that three sheets of paper are loaded in the default tray. If the printhead alignment fails on the first attempt, the printer will retry the alignment twice.
Do not power off the printer during this operation. The printer display will indicate busy until the operation is finished.
