Put an empty cart in the inkslot that is giving the trouble. At the other
end disconnect the tube from the damper. Take a syringe filled with a
cleaning fluid (Windex should be alright) and press the fluid through the
tube into the empty cart. Remove that cart and use another cart half filled
with cleaning fluid now. Fill the syringe again with cleaning fluid and now
press and suck the cleaning fluid through the inkline several times. Then
take the cart out and suck the rest of the cleaning fluid out of the
inkline. Put the original inkcart back in and suck the ink till the end of
the inkline and a bit more to get rid of air and some cleaner/ink mix.
Attach the tube again to the damper. A KK2 cleaning to get everything
alright again.

One way to detect a blocked needle is by pulling at the syringe when
connected to the tube, if there's more force needed on one inkline than the
other it must be the needle as no thinner part of the inkline exists between
cart and damper. Of course a nearly empty cart is the other possibility but
that one should be excluded from the start.
