Replacing the Printhead
Important
The inside surface protective cap 2 (g) is covered with
ink to protect the nozzles. Do not touch this area of the
cap or drop it. Doing so may stain the surrounding
area.
When handling the printhead, always hold it by the
grips (e) on the left and right sides.
Never touch the nozzles (a) or the electrical contacts
(b). Doing so may damage the printhead, or cause
printing problems.
Never try to re-attach the protective cap or packing
material removed from the printhead.
