container, then grasp the print
cartridge by the green top and remove
the cartridge from the container.
Gently remove both pieces of
tape-blue and white-covering the ink
nozzles and vent hole.
CAUTIONS: 1) If you don't remove
the white tape, you deplete the ink in
the cartridge prematurely. 2) Be
careful not to touch the ink nozzles or
the copper contacts. Fingerprints may
damage them.
Remove both
pieces of tape!
