Replacing Ink System Components 3-23
Caution
Always fill an empty ink tube with ink before con-
necting it to a printhead. Attempting to print with an
empty ink tube connected to a printhead will result
in enough air to be introduced to cause the print-
head to fail. This condition may be recoverable by
purging the cartridge of air (see “Purging the Print-
heads” on page 5-11 for instructions).
12. Connect the other end of the tube to the drain bottle, and
place the bottle on the printer platen or floor.
As ink begins to move through the ink tube from the ink
reservoir, the air in the tube is displaced with ink. The
greater the distance between the drain bottle and the ink
reservoir, the faster the ink will flow.
Tip
If the ink does not begin flowing, try disconnecting
and reconnecting the ink tube to the ink reservoir,
and reposition the drain tube needle within the ink
tube nozzle.
13. When ink has reached the end of the ink tube and begins
dripping into the drain bottle, remove the supply tube from
the drain bottle.
The ink tube automatically seals in the ink.
14. Label the new ink tube with the ink color on the connector to
the ink reservoir, and with the tube number (1 through 12)
on the connector at both ends.
Proper labeling will help ensure that the tubes are always
connected to the right ink reservoirs and printheads. This
will help reduce the possibility of reconnecting tubes to the
wrong printheads.
15. Connect the new ink tube to the printhead.
16. Swing the printhead assembly down into the printing posi-
tion, and push the printhead assembly down into position
until it engages the lock levers with a click.
17. Close the printer top cover.
18. On the control panel Front Page screen, press the B (Proceed)
key to park the printhead carriage into the service station.
