Cleaning Ink Jets 3-13
Filling Depleted
Cartridges and Resetting
Vacuum
Occasionally, you may find that the cartridge does not fill from
the Big Ink pack supply. The primary cause of this is failure to
open the clip on the ink pack tube after installing an ink pack. If
a cartridge leaks ink, it may have lost vacuum. To correct these
conditions:
1. Have a paper towel ready to catch any leaking ink during this
procedure.
This procedure may cause ink to drop on the floor.
2. Remove the ink tube from the routing clips on the track.
3. Remove the cartridge from the print head carriage. Do not
close the ink tube clip.
4. Move the cartridge, with the ink jets pointed up, below the
level of the ink pack (close to the floor), until ink and air bub-
bles begin to flow out of the ink jets.
5. Hold the cartridge in this position, and sharply squeeze the
sides of the cartridge repeatedly until no more air bubbles
emerge from the jets (when ink begins to flow from the jets).
6. To reset the vacuum, hold the cartridge, with the ink jets
pointed down (as when the cartridge is installed in the
printer), approximately three feet (90 cm) above the level of
the ink pack for exactly 10 seconds.
7. Reinstall the cartridge into the print head carriage.
