HP Black and Color Cartridge
15, 40, 45

PLEASE NOTE: If you have tried printing with your cartridge completely out of ink, you may have damaged the printhead. Inkjet printers work by heating a resistor inside the printhead which heats the ink before it is sprayed onto the paper. If there is no ink to keep the resistors cool, you stand the chance of frying them.

Always refill before you are completely out of ink.

1. Turn the cartridge upside down. Scrape off the plastic film and push the steel ballbearing in with a ball point pen.
2. Screw the needle on to the syringe and draw some ink into it. Fill the cartridge with about 30 ml of ink, or until it starts to come out of the fill hole.
3. Squeeze the sides of the cartridge and push the green plug into the fill hole. This can be removed and replaced each time you refill.
4. Set the cartridge on something (ie: block of wood) that will allow the printhead to hang off the edge, allowing any excess ink to drip onto a paper towel. Let it sit until the vacuum stabilizes and the cartridge stops dripping. Do not allow the printhead to touch the paper towel because the ink will be wicked out.

Replace the cartridge and run 1-3 cleaning cycles as per printer instructions.
Or print the following page: Black  Color

If necessary, leave the cartridge in the printer for up to 24 hours.
