Yes, a standard yield cartridge and a high yield cartridge can be installed together and used in your printer at the same time. Most standard yield cartridges and high yield cartridges are the same size and install the same way in your printer. The only difference between the two is that the high yield cartridge contains more ink.
Check out our video below to see how to install both a standard yield cartridge and a high yield cartridge. The HP 65 (standard yield) and the HP 65XL (high yield) cartridges we feature are identical in size!
