Doing so may stain your hands with ink or break the ink tubes.

5.1.3 Cleaning the Purge Unit

(1) Unplug the power cord from the wall socket.
(2) Plug the power cord again. After you hear the carriage moving out of the home position for
initialization, unplug the power cord again. The carriage will stop at the middle of the rail.
(3) Open the scanner unit.
(4) Clean the two head caps and wiper of the purge unit with a "Rubycel" stick that is a head
cleaner stick provided as a spare part.
NOTE: Do not use a cotton swab that may leave lint on the cleaned sections. Lint left on the
purge unit will affect the print performance.
NOTE: Use a new Rubycel stick and do not use the used one for any other purge units.
NOTE: During the cleaning jobs, take care not to touch the head caps or wiper directly by
hand or scratch their surfaces. Do not remove them from the head cap holder.
