Use all the ink in the cartridge !! Save Money
Continue to print even when your printer light comes on or you get a warning saying that your ink is low. Check the ink level in the cartridge and if it appears that there is some ink left, keep using it instead of changing the cartridge immediately. There is likely quite a bit of ink left in the cartridge; remember that the ink comes out in a spray so it doesn’t take much per page. Use it all and then shake the ink cartridge to break up any ink clogs.
You may get hundreds of extra pages out of a cartridge by doing this. Keep printing until the ink is almost completely gone (but be careful that you don’t run the printer with an empty cartridge).
