Sometimes when you refill a HP or Lexmark cartridge you get
dreaded message "Cartridge Not Recognized". What does this mean? It recognized
cartridge before I refilled it! HP and Lexmark have
print heads right on
cartridge and if you'll notice there is some circuitry on
side which also has electrical contacts that connect
print head to
printer. There are many contact points that must be made between
cartridge and
printer. If
connection isn't perfect you will get
error message.
There are a couple of things you can do to rectify this. First try snapping
cartridge in and out a few times. If that doesn't work remove
cartridge and clean off
foil contacts with a Q-Tip dampened with alcohol.
Be careful not to wipe
nozzles, where
ink comes out, or you might contaminate
ink inside
cartridge.
Before you put
cartridge back in use another Q-Tip dampened with alcohol and clean off
contacts inside your printer where
cartridge connects.
