The inside surface of the Protective Part (a) and Protective Part (b) is coated with ink to protect the
nozzles. Be careful not to touch these surfaces when removing the caps.

•
The Printhead contains ink to protect the nozzles. We recommend removing Protective Part (b) as you
hold it over the Printhead package or safely out of the way to avoid spilling ink and staining your clothes
or the surrounding area. If ink accidentally spills, wipe off the ink with a dry cloth.
•
If you need to put a Printhead somewhere temporarily before installation, do not keep the nozzles and
metal contacts facing down. If the nozzles or metal contacts are damaged, it may affect the printing
quality.
•
Do not reattach the removed Protective Part. Dispose of these materials in accordance with local regula-
tions.
