How To Perform Printhead Maintenance
[124] Swipe Printhead
7. Wipe the suction-head on a clean piece of new lint-free wipe before proceeding to the next
printhead.
IMPORTANT
During maintenance, be careful not to touch the nozzles or the nozzle plate as this can damage
the printhead.
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).
