3. Maintenance Routines.
Before you start printing, you should perform a noz-
zle check to see if all nozzles are present and firing.
After loading the media, follow the head gap proce-
dure (p.24) so the head height is correctly set.
Check the condition of the print heads by performing
a prime test. Press F1 in the main menu of the con-
trol panel (p.29). If one or more nozzles are missing,
you will have to clean the heads with one of the fol-
lowing procedures:
3.1
Purging, Flushing, Bleeding.
Purge (using ink).
If you purge the printheads, you are going
to apply air pressure in your subink tanks.
By doing this, you will force ink through the
nozzles. You can purge one or more heads at
the same time.
Make sure that the valves of the print heads
which you want to purge are set to “I”. The
other valves have to be switched to “S” (solu-
tion valve : “I”). Push the purge button to ap-
ply pressure. Use short intervals or one longer
push.
A quick purge is an impulsive purge (press and release the purge button very
quick). You press the purge button no longer than one second.
With a long purge, you press the purge button for up to
seconds. This is done to ensure that there is enough
ink in the print heads.
If you purge too long, the ink refill system will not
be able to keep up. This may result in air being intro-
duced in your system. You can check the condition of
the subink tanks in the main window of the control
panel. On the right top of the panel, you can read out
the different colors. If the color is mentioned with a
capital letter, the sub ink tank is full. If it is a lower
case letter, ink is being pumped to the sub ink tank.
When you purged the heads with ink, wipe the heads with a fiber free cloth to
remove the excess ink. Turn all the ink valves back into the “I” position and redo
the prime test.

The black and cyan print head will be purged when pressure is applied.
Cyan and yellow are displayed with a lower case letter
(c,y). This means that the level of the subink tanks is
too low and ink is being pumped to the subink tanks.
Do NOT use aceton to clean the
print heads. It will damage the
printheads unrepairably !
