To refill your HP 45 black ink cartridge, first gather a refill kit with black ink and a syringe. Remove the cartridge from the printer and locate the fill holes, which may be covered by a label. Use the syringe to slowly inject the ink into the cartridge, ensuring not to overfill, and then reseal the holes and reinstall the cartridge into the printer.
