How do I perform a printhead alignment on the HP Smart Tank 6000?

When the printer displays the letter 'A' on the Number Counter icon, it is performing printhead alignment and will print an alignment page. After the page prints and the Open Lid light blinks, place the printed page print-side down on the scanner glass, close the scanner lid, and press the blinking copy button to scan the page. Alignment is complete after the scan. (Page 10)
