Installing the Printhead
The printhead is sensitive to electrostatic discharge (ESD). Use ESD protection when
handling the printhead.
Do not touch the printhead cartridge ink couplings, nozzle surface, or the electrical
contacts when installing the printhead cartridge. Hold the printhead cartridge ONLY by
the handles.
To avoid drying out the printhead, do not open the printhead packaging until you are
ready to use it.
Open the printhead packaging over an appropriate receptacle to safely capture any
excess shipping fluid.
1. Ensure the printer is powered on and the ink cartridges have been installed.
2. Open the top cover.
3. Make sure the printhead latch [1] is in the open (vertical) position. Remove the cap
protectors [2] from the two fluidic couplings.
Note: The printhead latch will be in the open position. Do not close the latch before
installing the printhead. If the latch is accidentally closed, do not pry it open. Turn the printer
off and back on again. The latch automatically opens during power up if no printhead is
installed.
4. Remove the printhead from the packaging.
Note: If the foil packing is damaged, report the issue to Technical Support or your reseller.
Do not place the unprotected printhead cartridge on any surface. Protect the
printhead cartridge at all times from contamination such as dust or fibers.
5. Wipe any excess shipping fluid from the printhead cartridge with a clean, lint-free cloth.
