[105] Proper Swab Orientation
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.
• You may use either
isopropyl alcohol (99%) or flush when swabbing the printheads. Flush is
still the preferred cleaner for daily use, but alcohol can help when nozzles are difficult to
recover.
• Do NOT perform a purge before you swab the printheads.
NOTE
Tip: To help locate nozzles that need recovering remove the nozzle check print from the vacuum
table and place it on the floor under the carriage in the maintenance area. Make sure it is in the
correct orientation so the colors are aligned. The print represents a projection of the jetting
performance of each printhead. This makes it easier to trace a nozzle or group of nozzle outs
back to the area on the actual printhead nozzle plate that requires swabbing.
Procedure
1. Slide open the maintenance station drawer.
2. Dip a swab in a small container of flush or alcohol.
IMPORTANT
Swab one printhead at a time and use 1 swab per printhead. Do not re-dip a swab into
the flush or alcohol. Also note that flush is a solvent and should not be splashed or
sprayed around the printheads.
3. Position the swab at the far end of the printhead perpendicular to the nozzles and slowly draw it
towards you (minimum of 8 seconds per printhead). Hold the swab at an angle to limit dragging
