KK2's like Robert suggests. If that doesn't work and you have
made a bypass along the waste pad system to bottles at the base
of the printer(highly recommended anyway) then you cam apply a
vacuum at one or two of the waste ink tubes while they are in a
cleaning mode. That gets all nozzles open usually. A bit of a
mess in the capping station afterwards but by printing a paper
with broad stripes of all the colours that is usually gone in
some minutes.

The Eboni is the hardest to get right after an ink change. It
reacts with dye inks or whatever. Once it flows well you will not
have much problems later on. The 9500 firmware has some extra
cleaning modes that probably are better for the new quad inks.
Wonder how many of the Ultratone users are using the X500 models
instead of the X000 models.

With the vacuum system that I have I could pull out the
Generations ink in my 9000, spool the system with cleaner fluid,
water, emptied it again and draw the Ultratone in without using
any purge or initial fill, the heads were no used at all. It
printed well right away but the next day the black head was also
clogged. I had to use the vacuum again with a KK2 if I recall it
correctly. There was probably still some residue of the old inks
left.
