Printhead alignment icon
The Number Counter shows an A or a blinking A, or a “racecourse animation”.
Cause Solution
The printer is doing printhead alignment.
A racecourse animation appears on the display when the
printer is printing a printhead alignment page.
A solid "A" appears when the alignment page is printed.
A blinking "A" appears when the printer is scanning the
alignment page.
"A" disappears after the scan when printhead alignment is
complete.
After the alignment page is printed and the Open Lid
light blinks, place the printed page print-side down
on the scanner glass, close the scanner lid, and then press
the blinking Copy button to scan the page.
Printhead alignment is complete after the scan.
The Number Counter shows a blinking A. The Attention light and Resume light are blinking.
