Note:
Swab one printhead at a time to reduce ink waste during the purge and also to minimize
ink spill on your hand and arm. 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.

it immediately with a clean lint-free cloth.
