Printhead Maintenance - Maintenance for Select Printheads
Procedure
1.
On the top of the carriage there are manual purge valves. If you have
performed printhead maintenance and find that one or more printheads
require additional maintenance, turn off the valves of all the other colors,
and leave open the one you want to clean (yellow in this example).
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 (see the next section).
