Printhead Maintenance
b) Suction-head was not kept level during travel across the nozzle plate;
c) Suction-head was pulled too quickly or unevenly across the nozzle plate.
[133] Swipe Printhead
6. Wipe the suction-head on a clean piece of new lint-free wipe before proceeding to the next
printhead.
NOTE
During maintenance, be careful not to touch the nozzle plates as this can damage the
printhead.
7. Repeat steps 5 and 6 until are printheads are done.
8. Use a dry swab to pick up any excess ink from around the edge of the printhead opening in the
pan (see the white line with arrows in the image below). Take special care to remove any excess
ink, flush or alcohol on the metal plate between the pan and the printhead (see the area covered
by the two ellipses in the picture below). A single swab can be used for each color channel or use
it until the swab becomes saturated with ink.
9. Slide the maintenance station drawer back to its closed position. The carriage will move back to
its previous print-ready height.
IMPORTANT
Close the drawer gently to avoid disturbing the ink vacuum. A hard bump can break the
meniscus vacuum in the ink lines and thus allow air into the lines, which blocks the
nozzle until a purge is performed
10. Print a Nozzle Check to evaluate print quality.
NOTE
If the Nozzle Check print shows that a printhead still has a few nozzles out you can slide
the suction-head over that printhead again. Then print another Nozzle Check and if
there are still nozzles out, you can perform printhead maintenance on the printhead of
the same color only (See Maintenance for Select Printheads below).
