HP Photosmart Pro B9180 Photo Printer - Manual (Page 40)

To replace printheads
1.
Open the top door.
2. Press and hold OK until the printhead assembly moves to the left side of the printer
and stops.
3. Raise the blue printhead assembly cover. Before you begin, notice the metal bar
that holds down the cover. Pull the cover forward by the handle so that it unclips
from the metal bar, then raise it up out of the way.
4. Remove the faulty printhead. To do this, raise the fold-down blue handle on the
printhead, and use it to pull the printhead straight out of its slot.
5. Shake the new printhead vigorously, at least six times, before opening the package.
6. Lift out the printhead. Be careful not to touch the gold-colored contacts on the
printhead. In particular, guard against scratching the contacts with your fingernails.
