Procedure
NOTE
Swab one printhead at a time to reduce ink waste during the purge and
also to minimize ink spill on your hand. In order to achieve the most
effective swab, it is best to swab immediately after a purge while the ink
is still dripping from the printheads. Close the ink valve so that the ink is
under slight pressure to help clear debris from around the nozzles.
1.
Slide open the maintenance station drawer.
2.
Close the ink purge valves of the other colors, but leave open the valve for
the color you will swab.
3. Dip a swab in a small container of flush.
NOTE
Use 1 swab per printhead. Do not re-dip a swab into the flush. Also note
that flush is an aggressive solvent and should not be splashed or sprayed
around the printheads.
4.
Press the Purge button to initiate a purge.
5.
Within 3 seconds of pressing the purge button, close the remaining purge
valves. The carriage will lower to its purge height (4mm above the table
surface) and the ink will continue to drip from the printheads.
6.
While the ink is still dripping, position the swab at the far end of the
printhead perpendicular to the nozzles and slowly draw it towards you. Do
not let the seam in the foam touch the nozzles or the nozzle plate.
NOTE
It is important to ensure the flush-soaked swab contacts only the nozzle
face of the printhead. Also if there is any residual ink left on the plate after
swabbing, use a lint-free cloth soaked with flush to remove it (but be
careful not to touch the nozzles).
