Filling these refillable cartridges is extremely simple. Simply remove the plug, simply inject the ink, simply replace the plug. That's all there is to it!
The cartridges come with permanent chips. Although accurate ink levels will not be displayed by the printer, the cartridges are transparent, so you can refill whenever you see that a cartridge needs it, at your full convenience.
*NOTE* The cartridges are provided empty. In order to use them, you will also need to purchase an InkOwl inkjet refill kit compatible with these cartridges. It is essential that you use an ink specifically formulated to work in HP printers. You can find them using our search engine.
