Cartridges are micro-chipped. The chip stores a record of how much ink has been used. If you install a non-chipped cartridge, or refill an empty one (without resetting the chip's record) it won't work.
Third party cartridges are usually recycled cartridges, where the chip has been reset. If the job has been done properly the cartridge will work (because the printer sees it as a new 'official' cartridge) but it sometimes seems to go wrong.

This is done by switching on the printer, opening the drop-down door so that the cartridges move to the centre and are ready for removing. At this point pull the mains plug for the printer out of the socket, remove the cartridges, refill as necessary and then replace cartridges in the printer.
Now you can replace the mains plug in the socket and close the drop-down door.
The printer will still occasionally tell you that the ink levels are low but this is just ignored as you should now be fully aware of how full/empty the cartridges are. I check mine every couple of months to make certain that they are never, ever run too close to being empty.
I thought other people with HP printers who wished to re-fill and were being foiled by the in-built microchips might be interested in this.
