Identifying the printheads
Warning: Do not loosen or remove all printheads at the same time. If all printheads are loosened or removed,
your reference to readjust will be lost.
Notes:
• Whenever a printhead is removed, it is necessary to perform the “Mechanical alignment” on page 4-73,
the “Black printhead electronic alignment” on page 4-78 (if necessary), and the “Color printhead
electronic alignment” on page 4-79.
• The front cover assembly must be installed and closed before any printhead alignment can be performed.
It is not necessary to remove the cover to access the printheads.
• If there is a protective lens cover on the new printhead, it must be removed before installing the
replacement printhead.
