Inserting and replacing the print cartridges
Preparing the printer and cartridges
1 Make sure the power is on and you
have removed the cardboard from
inside the device.
2 Raise the top cover of the printer.
3 Remove the bright pink tape from
the cartridges.
Do not touch the ink nozzles or the
copper-colored contacts, and do not re-
tape the cartridges.
Inserting the cartridges
1 If you are replacing a Black or
Photo cartridge, push down and pull
outward on the cartridge in the right
stall to remove it.
2 Hold the new Black or Photo
cartridge with the label on top. Slide
the cartridge at a slight upward
angle into the right stall so the
copper-colored contacts go in first.
Push the cartridge until it snaps into
place.
