Removing and Installing Ink Cartridges
Make sure you have your replacement cartridges handy before you begin. You must install new
cartridges immediately after removing the old ones.
Caution: Leave your old cartridges in the printer until you are ready to replace them to prevent the print
head nozzles from drying out. Do not open ink cartridge packages until you are ready to install the ink.
Cartridges are vacuum packed to maintain reliability.
