6 side streams in ARIA?!?

Hi,

My department recently bought an Aria and I was among the first ones to go
through operator's training for it. So, although I have previous flow
experience, I am largely a beginner in the sort world.

Today I tried to sort some cells using 100u nozzle and LOW sort mode (for
the first time; most of the time we use 70u nozzle and HIGH sort mode). The
stream looked OK but, when I applied the voltage and used TEST SORT button,
I got 6 side streams instead of 4!??! (I will try to attach a picture but
I've never seen any attachment going through) Is there a simple explanation
to this phenomenon and how can I resolve this? When I move the sliders used
to adjust the position of side streams, the outer two side streams on each
side respond. But, the center stream splits/gets 2 side streams of its own
after applying a voltage, and they are inresposive to the movement of any
sliders. These two are not too much apart but are clearly visible as
separate streams in camera window...

Any comment is more than welcome.

Sincerely,
Vinko
