Printhead Maintenance - Maintenance for Select Printheads
Procedure
1. On the top of the carriage there are 4 or 5 purge valves. If you have performed a printhead
maintenance and find that one or more printheads require additional maintenance, turn off the
valves of all the other colors.
2. Perform all of the steps for printhead maintenance again, but only on the affected printheads.
NOTE
Isolating individual colors to purge does not perform a stronger purge, but it does
conserve ink.

3. Remember to open any purge valves that were closed for this procedure.
NOTE
If a purge valve is left closed, there is no vacuum pressure to hold the ink and it will
drip out of the printhead. Drops of ink will appear on the media if you print with purge
valves closed.
4. If problems still persist, perform the swab procedure on the affected printhead.
