The printer will normally perform an alignment automatically
whenever any printhead is replaced.
However, you can turn off this automatic alignment
by choosing the icon,
then Internal RIP Settings > Align Calibration > Off.
You can also request a printhead alignment from the front panel
at any time by choosing the icon,
then Utilities > Calibrations > Printhead Alignment.
In this case the printer will align the printheads immediately;
or, if an image is being printed, as soon as the current print job is finished.
The alignment procedure requires a minimum paper size of A1/D-size (24 inches).
You can use this feature if the image quality print
indicates an alignment error.
When the front panel displays Ready, you are ready to print.
Make sure the printer window and the right door are closed after you replace the HP supplies.
The printer will not print while these are open.
