How to Refill a Dell 7Y743 Ink Cartridge
The Dell 7Y743 ink cartridge works with Dell All-in-One Printers A940 and A960. Because buying a new cartridge is expensive, you could use refill kits to reuse your ink cartridge when the ink runs out. When purchasing, check that the refill kit is specifically labeled for use with a Dell 7Y743 ink cartridge. The manufacturer might label the black inkjet refill kit for use with other ink cartridge types as well, and that is fine.

Use the small suction syringe supplied with your refill kit to poke through the rubber hole at the bottom of the refill clip.
