Note:
It is important to ensure the flush-soaked swab contacts only the nozzle face of the
printhead.
[170] Swab the Yellow Printhead
7. Rotate the swab by 180 degrees and repeat the previous step.
8.
Discard the swab and repeat Steps 2 to 6 for all the other printheads (if needed).
9.
Perform Printhead Maintenance.
10.
Once finished, all residual flush and ink in the gaps around the head should be carefully
wiped away with a clean swab.
11. Run a Nozzle Check print or an image test print and verify that all nozzles are firing
properly.
Note:
If the problem persists, you can swab multiple times. Use a new clean side of the swab
each time (this means a maximum of two swipes per swab). It is possible that as many as
ten swipes can be required. If purging and swabbing does not recover a blocked nozzle,
holding a flush-soaked swab against the blocked nozzle on the printhead for at least ten
seconds is an effective way of clearing the blockage.
12.
Run another nozzle check, if necessary. When the Nozzle Check print does not show any
nozzles out, the printer is ready to produce quality images.
