Swab Printheads
Attention:
Never "scrub" the printhead with a swab as this will drag debris into other nozzles.
Always slowly move the swab across the printhead with the swab at a slight angle and not
perpendicular to the printhead.
Never use Isopropyl alcohol to clean the printheads.
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.
