How to Swab a Single Printhead
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 im-
mediately 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.
Slide open the maintenance station drawer.
1.
Close the ink purge valves of the other colors, but leave open the valve for the color you
2.
will swab.
Dip a swab in a small container of flush.
3.
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.
Press the Purge button to initiate a purge.
4.
Within 3 seconds of pressing the purge button, close the remaining purge valves. The
5.
carriage will lower to its purge height (4mm above the table surface) and the ink will
continue to drip from the printheads.
While the ink is still dripping, position the swab at the far end of the printhead and
6.
slowly draw the swab towards you. Hold the swab at an angle to limit dragging debris
from one nozzle to the next. Do not let the seam in the foam touch the nozzles or the
nozzle plate.
