Swab Printheads
Flush (3010106646 Flush UV 1Liter) or Isopropyl alcohol (99% pure)
Bottle-HDPE 125ml for flush (3010105433)
Nitrile Gloves
Safety Glasses with side guards
IMPORTANT
Never "scrub" the printhead with a swab as this will drag debris into other nozzles.
Always move the swab across the printhead nozzles from back to front (minimum of 8 seconds
per printhead).
Do not allow swabs to be contaminated with any dust or dirt prior to use.
Note that the swab has a seam that can damage the printhead nozzles; use only the semi-curved
foam sides of the swab.
CAUTION
Use appropriate safety equipment — nitrile gloves, an apron, and safety glasses with side
shields to protect your eyes.

NOTE
Perform Printhead Maintenance before and after you swab the printheads. This ensures that the
swabbing is more effective at cleaning the printheads as any debris in the ink is first sucked out of
the nozzles and then any residual flush or alcohol left on the nozzles after maintenance is also
sucked away.
Procedure
1.
Perform Printhead Maintenance (see previous section). This also eliminates the need for a purge
before you swab.
