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.
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.
