8.5. Bleeding air out of the ink filters

When suddenly an increase of the under pressure is needed to hold the ink properly in the
nozzles without pooling, there is a big chance that an air-bubble is sitting into the ink
tank; This can be caused by a previous low ink level in the main ink tank, by having
poured ink into the main tank that contained a lot of air or just an accumulation over time
of small air bubbles in the ink.
At that time, the user has to bleed the air out of the ink filters. Only then, an accurate ink
supply can occur.
