How to install compatible ink cartridges in the HP Deskjet 3721
What you need to know before the installation:
- Do not touch the chip or the ink nozzles. This can result in clogs, ink failure and poor electrical connections.
- Avoid mixing cartridges from different suppliers simultaneously – the printer may not recognize them properly.
- The Smart Ink team strongly recommends using only high-quality ink from one producer to extend printer life.
- Remove the plastic protective cap from the ink cartridge.
- Use the pink pull tab to remove the protective tape.
Attention: Do not remove copper-colored contacts from the ink cartridge. - Install the cartridge into the corresponding slot, and push it forward until the cartridge firmly locks into place.
Note: The color ink cartridge should be installed in the left slot. The black ink cartridge should be installed in the right slot.
