If the printing quality is still unsatisfactory, you must
manually clean the cartridges:
1
Open the machine and take the cartridges out of
the holder (see also Changing Cartridges). Clean
the contacts (A) with a dry, lint-free cloth.
2
Lay a lint-free cloth on a flat surface. Moisten half
the cloth (A). Hold the cloth firmly to prevent it
from wrinkling. Place the "nose" (= nozzle side) of
the cartridges against the moistened area (A) and
pull the cartridge a single time in the direction in-
dicated by the arrow (B) into the dry area (C).
Æ
Be sure to hold the cartridge in the correct po-
sition according to the figure above to prevent
damaging the nozzles!
Never touch the nozzles and contacts with bare
fingers and do not shake the cartridges.
