HP DeskJet 3630 Ink Cartridge Safe Handling Precautions
Leave Cartridges in Bags Until you are Ready to Install Them
Do not remove the cartridges from their anti-static bags until moments before installing them into the printer. Why? Because these units contain sensitive electronic parts, keep them bagged until ready to install. Indeed, static charges could destroy them when left outside of the bag too long before installing. So do not remove them from bags until ready to use them.
Keep the Ink Nozzles Covered!
Also, do not remove the protective tape on the ink nozzles until you can install them right then. Leaving them open for too long can dry out the ink inside, and clog the nozzles. So, it’s best not to remove these tape strips, as pictured next, until you’ve already removed the old cartridges.
Never Force Cartridge into the Printer
During installation, they should easily snap into place with light pressure from a single index finger. If you must apply more force, then remove it and try again.

When buying these cartridges, ask for an HP 63 cartridge set.
